Firefox 59 features performance and user interface improvements, as well as numerous other minor changes. At least eighteen security issues are fixed in the new version.

Particularly welcome are new Privacy and Security settings (Menu > Options > Privacy & Security) that will stop websites from asking to send notifications.

Note: Windows 7 users may have trouble using certain Windows accessibility features, such as the on-screen keyboard, when Firefox 59 is installed. Mozilla is working on a fix for this issue.

Update: Firefox 59.0.1 is also now available. It fixes a single security bug.
