Dark Mode Rant

What you see above is what I see after a few seconds of viewing a web site in ‘dark mode’.

Web sites are traditionally shown with dark text on a light background. Which is reminiscent of something… (checks notes)… that’s right, books! Why change something that’s worked fine for literally millennia? Apparently because a lot of people think light text on a dark background looks cool. And, to be fair, some people claim that using dark view is easier on their eyes.

So now we have a ton of web sites, apps, and other assorted crap showing up on our computer screens that is almost entirely illegible to a large proportion of the population (well, me for sure, and I’m guessing I’m not the only one).

When I look at white text on a dark background, after about five seconds, all the lines start to blur together (see image above), and I’m unable to continue. If I persist, I just end up with a headache. For the record, I’ve had my eyes checked, and aside from needing to update the prescription for my reading glasses, my eyes are fine.

Here are a few links to web sites that default to dark mode:

A request to web designers and developers: if you can’t resist making your web site dark mode by default, please, please at least provide some method for viewing it in light mode.

Some browsers have built-in features that allow viewing dark sites in light mode. But they’re inconsistent. Firefox has Reader View, which reformats a web page to show it like a book, with less clutter and — more importantly — dark text on a light background. Sadly, the Reader View button, which normally appears at the right end of the address bar, doesn’t always show up. That’s apparently because it’s only able to handle individual posts/articles, not other types of pages.

There are many Firefox plugins for showing web pages in dark mode, but initially I wasn’t able to find one that does the opposite. I had been struggling with a plugin called Dark Reader, which sort of worked, but only with a lot of fiddling, presumably because it was designed to do the opposite of what I want.

Recently, however, I discovered a Firefox plugin called Tranquility Reader. This one does exactly what I want, forcing page text to black and page background to white. So far, it’s worked perfectly on every page I’ve tried.

When installed in Firefox, Tranquility Reader adds an icon to Firefox’s toolbar. Click it once to view the current page as black text on a white background. Click it again to go back to the page’s default colour scheme. Simple!

If you ever find yourself struggling to read dark mode web pages, try Firefox with Tranquility Reader. It may save you from a headache or two.

Patch Tuesday for July 2021

It could be argued that Microsoft has done us all a favour in making Windows 10’s updates unavoidable. Certainly, as long as nothing goes wrong, it’s less work than futzing around with Windows Update on every computer. And forced updates mean that Windows computers used by less tech-savvy folks stay up to date with security fixes, which makes everyone safer.

It’s also true that increasingly, software and firmware updates for all our devices happen whether we want them or not. By default, mobile devices update themselves. Other electronic equipment, like smart televisions, digital video recorders, amplifiers, and even some network equipment are now doing the same.

But I just can’t shake the feeling of discomfort I get when I think about my computer being messed with at the whim of some Microsoft flunky. Perhaps some day I’ll be more comfortable with it. In the meantime, as long as Microsoft continues to screw up updates, sometimes breaking thousands of computers worldwide, I’ll continue to feel this way.

This month’s Microsoft updates

According to my analysis of the data available from Microsoft’s Security Update Guide, we’ve got updates for Edge, Office, Exchange Server, SharePoint, Visual Studio Code, Windows (7, 8.1, and 10), and Windows Server, addressing a whopping one hundred and thirty-three vulnerabilities in all.

As usual, Windows 10 updates will be installed automatically over the next few days, although you may — depending on your version of Windows 10 — be able to delay them for about a month. You can check for available updates and install them right away by heading to Start > Settings > Update & Security > Windows Update.

Windows 8.1 users also have the option of using automatic updates, but if that’s disabled, you’ll need to go to Start > PC Settings > Update & Recovery > Windows Update.

There seem to be one or two updates that are freely available for all Windows 7 computers, so it’s worth checking Windows Update. When Microsoft releases free updates for Windows 7, you know they’re important. Go to Start > Control Panel > Windows Update to check.

Adobe Updates

Adobe joins the fun again this month, with an updated version of the free and still ubiquitous Adobe Acrobat Reader. Version 2021.005.20058 of Reader includes fixes for thirteen security bugs.

Reader normally updates itself, but you can make sure, by navigating its menu to Help > Check for updates...

Firefox 90

Perhaps coincidentally, there’s also a new version of Firefox today. Firefox 90 addresses nine security vulnerabilities in earlier versions.

By default, Firefox will update itself, but you can encourage it by clicking its ‘hamburger’ menu at the top right, and navigating to Help > About Firefox.

Changes coming to Chromium and Firefox

There’s interesting news from the world of web browser software. And when I say ‘interesting’, I mean possibly extremely annoying, depending on which browsers you use, and how you use them.

First up, there’s been an interesting debate in the Firefox bug list, since 2014, about whether to change the behaviour of the Backspace key.

It’s possible that you weren’t even aware that you could use your keyboard’s Backspace key to navigate to the previous page in Firefox. This functionality has existed in most browsers at one time or another, but it was removed in Google Chrome version 52 in July 2016. It’s a convenient shortcut for doing the most common thing you can do in a web browser, and I have personally used it for years.

The problem is that some users apparently run into trouble when they try to use Backspace to erase the previous character in a text box on a web page, such as in a form, only to find that they have navigated to the previous page instead. This can result in the loss of form data, and I imagine that could be very annoying.

Because of the debate about this, Mozilla software engineers went so far as to track the usage of the Backspace key in Firefox. And while I applaud their methods, I don’t necessarily agree with their analysis. For example, they found that the Backspace key is the most pressed keyboard shortcut in Firefox, with forty million users pressing the key and triggering a ‘previous page’ navigation every month.

By comparison, the next most common keypress is Ctrl-F, which is the browser-universal key combination for searching within the current page. That keypress is used by about sixteen million users per month. Fifteen million users per month use F5 and Ctrl-R to reload the current page.

So far so good, but the Mozilla engineers somehow used this information to conclude that many of the Backspace presses (and subsequent navigation to the previous page) were unintentional. I don’t follow their reasoning, frankly. Isn’t it just as likely that that people frequently use the Backspace key to go to the previous page?

Regardless, Mozilla is changing the behaviour of the Backspace key in Firefox from version 86 onwards. That version is scheduled for release on February 23, 2021. There will be workarounds, so this isn’t likely to be a huge problem for most people, but there will clearly be a bit of fumbling as people get used to the change.


Meanwhile, Google is planning to cut off access to several of its services for Chromium-based web browser software, on March 15, 2021. This won’t affect Google’s own Chrome browser, but any browser built on the Chromium browser engine that isn’t Chrome will lose access on March 15.

The Google services involved include bookmark synchronization, the ‘safe browsing’ feature, search suggestions, spell checking, and others. It’s important to recognize that these functions are not necessary for basic browser use, and their loss likely won’t affect many users. Losing search suggestions and spell checking seem like minor annoyances at worst. Loss of the safe browsing feature is unfortunate, but other safeguards exist. Anyone who uses bookmark sync is going to be annoyed at losing that feature.

At the same time, it’s interesting to note that people who are using a non-Chrome Chromium browser to avoid using Google software never really accompished their goal if they used any of the soon-to-be-disabled features. They might as well have been using Chrome all along.

Google maintains that it was never their intention to make these services available to non-Chrome browsers. Which is why, despite having frequently expressed annoyance at Google for discontinuing software and services that they had strenuously promoted, this change doesn’t bother me.

Firefox 78

Mozilla released Firefox 78.0 on June 30th, and followed up with Firefox 78.0.1 the next day, to fix a specific issue which “could cause installed search engines to not be visible when upgrading from a previous release.”

Changes in Firefox 78

The new Protections Dashboard, accessible from the Firefox menu or by browsing to about:protections, provides a summary of various protections provided by the browser. If Enhanced Tracking Protection is enabled, you’ll see the number of times Firefox has blocked social media trackers, cross-site tracking cookies, fingerprinters, and crypto-miners. If you’re using Firefox’s password manager, Lockwise, and you’ve signed up for breach alerts, those alerts will be shown here, along with references to exposed passwords.

The Firefox uninstaller will now offer an alternative to uninstalling Firefox when it’s not working properly: a Refresh button. “Refreshing Firefox can fix many issues by restoring Firefox to its default state, while saving your essential information like bookmarks, and passwords.”

The new version also includes improvements to video calls and videoconferencing, as well as graphics performance.

Firefox 78 addresses thirteen security vulnerabilities in earlier versions.

Firefox updates itself automatically by default. If you’ve disabled that option, or just want to get the new version right away, navigate the browser’s ‘hamburger’ menu at the top right to Help > About Firefox. You’ll see an update button if a newer version is available.

Firefox 76 and 76.0.1

Announced on May 5, Firefox 76 tightens up password management and related security in several ways:

  • Lockwise, the password manager built into Firefox, now prompts for your Lockwise master password when you try to show or copy a password. If you’re not using a master password, Lockwise will prompt for your device’s password. Previously, Lockwise only prompted for the master password once, on Firefox startup.
  • Firefox now checks all your saved passwords against records from known breaches. Any password known to have been revealed in any breach will show in your Logins & Passwords list with a special icon. A different icon is shown if the associated site was breached since you last changed your password for that site.
  • Firefox can now generate secure, complex passwords for you.

Other changes in Firefox 76 include improvements to the Picture-In-Picture feature, and native support for more complex audio applications, including Zoom. There are also some minor cosmetic tweaks to the address bar and bookmarks bar.

There are eleven security fixes in Firefox 76 as well.

Default installations of Firefox keep themselves up to date, but you can hurry the process along by navigating its ‘hamburger’ menu to Help > About Firefox.

Firefox 76.0.1

The release of Firefox 76 was followed up quickly by Firefox 76.0.1, which fixes two bugs, neither of which are security-related.

Firefox 75.0

April 7’s announcement of Firefox 75.0 came just a few days after the release of Firefox 74.0.1, a special version that addresses two critical security vulnerabilities.

Firefox 75.0 features a reworked address bar, and includes fixes for another six security bugs.

The new address bar functionality may trip up some users initially, but it does appear to be an overall improvement. The changes are as follows:

  • Searching using the address bar on smaller screens is now optimized, and should be less confusing.
  • Clicking the empty address bar, or clicking on an address in the address bar, will now show a list of ‘top sites’. These are the sites you visit most often.
  • The address bar is now slightly larger, and expands slightly when clicked. The font is also larger, and suggested URLs are shortened to provide more useful context.
  • When entering search terms, Firefox will now suggest additional terms it thinks may be relevant.
  • If you start entering a URL that is already open in another tab, Firefox will show a ‘Switch to Tab’ entry in the suggestions.

Depending on your configuration, Firefox will typically update itself in the days following a new release. If you prefer to do this yourself, or you’re not sure which version you have, navigate Firefox’s ‘hamburger’ menu (at the top right) to Help > About Firefox. If a newver version is available, you’ll be given the opportunity to install it.

Firefox 74.0

A new version of Firefox fixes some annoying problems with pinned tabs, improves password management, adds the ability to import bookmarks from the new Chromium-based Edge, resolves some long-standing issues with add-on management, introduces Facebook Container, and addresses several bugs, including twelve security vulnerabilities.

The release notes for Firefox 74.0 provide the details.

Starting with Firefox 74.0, it is no longer possible for add-ons to be installed programmatically. In other words, add-ons cannot be added by software; it can only be done manually by the user. Add-ons that were added by software in previous versions of Firefox can now be removed via the Add-ons manager, something that was previously not possible.

Facebook Container is a new Firefox add-on that “works by isolating your Facebook identity into a separate container that makes it harder for Facebook to track your visits to other websites with third-party cookies.” People who are concerned about Facebook’s ability to track their activity across browser sessions and tabs can use this add-on to limit that tracking, without having to access Facebook in a separate browser.

You can wait for Firefox to update itself, which — assuming that option is enabled — may take a day or so, or you can trigger an update by navigating Firefox’s ‘hamburger’ menu to Help > About Firefox. You’ll see an Update button if a newer version is available.

Firefox 73.0

There’s another new version of Firefox: 73.0. Despite the major version bump, there are no big changes. However, it’s an important update, because it addresses several security vulnerabilities. There are also fixes for a few long-standing annoyances.

According to the security advisory for Firefox 73.0, six security bugs are addressed in the new version. None of them are flagged as having Critical impact, but they all look nasty.

Firefox’s page zoom feature is very handy for viewing web sites with unfortunate font size choices. It’s not new: Firefox has had this feature for years. What is new is that you can now set a global zoom level, which seems likely to be useful for folks with impaired vision.

To zoom the page you’re looking at, hold down the Ctrl key and move your mouse’s scroll wheel up and down. To change the global zoom level, click Firefox’s menu button, and select Options. In the General section, change the Default Zoom setting.

Firefox now shows web page background images with a border when Windows is configured to use high contrast mode. Previously, background images were disabled in high contrast mode.

Firefox will now only prompt to save login credentials if at least one form element has been changed.

To see which version of Firefox you’re using, navigate its menu to Help > About Firefox. If a newer version is available, you should see a button or link to install the update.

Firefox 72.0 and 72.0.1

Security fixes and some welcome changes to notifications and tracking protection were released in the form of Firefox 72.0 on January 7. Firefox 72.0.1 followed the next day, adding one more security fix.

Site notifications are those annoying messages that pop up when you’re browsing web sites, asking — somewhat ironically — whether you want to see notifications for that site. You can still choose to see those, but now Firefox lets you suppress them. To control notifications, navigate Firefox’s Settings to Privacy & Security > Permissions, then click on the Settings button next to Notifications.

Firefox’s already helpful tracking protections were enhanced in version 72 with the addition of fingerprint script blocking. Fingerprinting is a technique used by many companies to better understand you and your online behaviour. While arguably harmless (it’s mostly about providing better ad targeting) fingerprinting is also creepy and a privacy concern. By default, Firefox now blocks scripts that are known to be involved.

Current versions of Firefox default to updating themselves automatically, but you can check for available updates by navigating Firefox’s menu to Help > About Firefox.

Firefox 71.0

Firefox is my current web browser of choice. I use Google Chrome sparingly, because it’s gotten so bloated and resource-intensive that I can’t leave it running. Perhaps that will change; it wasn’t that long ago that Chrome seemed like the best choice.

I still use Opera and Vivaldi for certain specific activities. And while there’s still no way I can stop using Internet Explorer altogether, I only do so when absolutely necessary. I avoid Edge completely, as it seems hopelessly buggy. There are other alternatives, but for now, Firefox is my main browser.

The latest version of Firefox is 71.0. The new version improves some existing features and adds a few more. Several bugs are fixed, including some security vulnerabilities.

New in Firefox 71.0

  • The integrated password manager, which Mozilla calls Lockwise, now differentiates between logins for different subdomains. If you have one login for subdomain1.domain.com and another for subdomain2.domain.com, they will no longer be conflated.
  • Lockwise will also now display a warning if it finds one of your passwords in a list of potentially compromised passwords.
  • The Enhanced Tracking Protection feature will now show a notification when Firefox blocks cryptomining code. You can see what Firefox is blocking by clicking the small shield icon at the far left of the address bar.
  • You can now view video in a floating window using the Picture-in-picture feature. Look for a small blue button () along the right edge of a video and click it to pop out the PiP window.

Security fixes

Eleven security vulnerabilities are addressed in Firefox 71.0. None of them are ranked as critical, and there doesn’t seem to be any evidence that any have been used in actual attacks. Still, it’s best to close those holes before they can be exploited.

How to update Firefox

Check which version of Firefox you’re running by navigating its ‘hamburger’ menu (at the top right) to Help > About Firefox. If you’re not running the latest version, you should see a button that will allow you to upgrade.
