Firefox 87 and 78.9 ESR fixes several security holes and improves privacy [changelog]

On: March 23, 2021

Briefly informed: Tomorrow Mozilla will distribute the updated Firefox 87.0 and 78.9 ESR via the update function. Both can be installed today.

We will of course deliver the list of updates later. There will certainly be resolved security problems there. A new function was tried out in the beta. "Find in Page" can now display markers next to the scroll bar that corresponds to the position of the hits.

Changelog Firefox 87

New

  • With private browsing and the rigorously enhanced tracking protection with SmartBlock, which provides backup scripts to ensure that web pages load properly, you will have fewer problems with web pages.
  • Starting with Firefox 87, we set the standard referrer policy to "strict-origin-when-cross-origin", which cleans up the sensitive information of the user-accessible in the URL. With this new, stricter referrer policy, the information for requests sent from HTTPS to HTTP are reduced. Also the path and query information for all cross-origin queries.
  • The “Show all” function of the “Find in page” function now shows checkmarks next to the scroll bar that corresponds to the position of the hits on the page.
  • We're proud to announce full support for the VoiceOver screen reader built into macOS.

Fixed issues:

  • Mozilla fixes nine security vulnerabilities, three of which have been rated as "High".
  • We fixed several key accessibility issues:
  • Video controls now have visible focus styling, and video and audio controls are now keyboard navigable are now read by screen.
  • HTML readers.
  • Firefox is now using a useful first focus in the Add-ons Manager.
  • Firefox now runs a name / description change event when the content of aria-labeled by / described by changes.
  • The backspace key has also been deactivated as a navigation shortcut for the back navigation key when filling out forms. “To re-enable the backspace key combination, you can change the about: config setting browser.backspace_action to 0. You can also use the recommended keyboard shortcut Alt + Left Arrow (Command + Left Arrow on Mac) instead. "
  • Removed some elements from the library button that were not used often or that have other access options in the browser.
  • We have simplified the Help menu by reducing some superfluous entries or entries that refer to support pages that can also be reached via the entry "Get help".
  • We have greatly simplified the "Web Developer" menu.

With the launch of Firefox 87 as the final version, Firefox 88 will also be pushed into beta and Firefox 89 into nightly.
