Mozilla Firefox

Mozilla Firefox 66.0 was released two days ago. Now it’s available in main repositories of Ubuntu 16.04, Ubuntu 18.04, Ubuntu 18.10.

Firefox 66.0 release highlights:

  • Block sound auto-play. You can add exceptions, or turn the feature off.
  • Easier search via a redesigned new tab in Private Windows
  • Basic support for macOS Touch Bar
  • Title bar is hidden by default in Linux (Unfortunately I still see it in Ubuntu build).
  • Search from the tab overflow menu
  • Scroll anchoring keeps content from jumping as images and ads load at the top of the page
  • Redesigned certificate error pages
  • Improved extensions to load web page faster
  • Enabled AV1 support on 32-bit Windows and MacOS.

Upgrade to Firefox 66 in Ubuntu:

For all current Ubuntu releases, simply open Software Updater and install the updates after checking for updates.

If you don’t see the Firefox updates, go to Software & Updates and make sure the security and updates repositories are enabled in Updates tab.
