The latest Firefox fixes a few bugs that caused crashes and hangs in relation to Flash, bookmarks, and Facebook. There are no security-related changes in this release.

The version 41.0.1 release notes provide additional detail.

It looks like Mozilla finally decided to stop putting all previous release notes for the associated major version on every release notes page. Instead, they’re adding a link to the major version’s release notes at the top of the What’s New list. Unfortunately, they managed to mess that up with this release, because the Reference: Release notes for Firefox 41.0 link actually points to the notes for Firefox 40.0. Here’s a link to the Firefox 41 notes.
