Firefox Developer Edition overview

Firefox Developer Edition (was Aurora) is the rapid-fire release channel for the next iteration of the Firefox Web browser. The Developer channel is where users can test the latest features and innovations. Users can expect an increase in polish from the raw, cutting edge features in the nightly builds. These releases may not be as stable as beta or final releases.

With Firefox Developer Edition:
  • Experience the newest innovations in an unstable environment that's not for the faint of heart
  • Provide feedback on features and performance to help determine what makes the final release

What’s new in version 126.0

  • A simpler and more unified dialog for clearing user data is now available.
  • In addition to streamlining data categories, the new dialog also provides insights into the site data size corresponding to the selected time range.
  • Enabled AV1 hardware decode acceleration on macOS for M3 Macs.
  • For consistency with Firefox desktop and addons.mozilla.org, Firefox for Android's "add-ons" settings have been renamed to "Extensions".
  • Added "Linux" to Firefox for Android's User-Agent string to fix some website compatibility issues.

I think MacUpdates is very late off the blocks for this one. V. 62.0 came out about two weeks ago, now its up to 62.0.B13 The browser in its current edition has a few faults in rendering pages, but its not bad. There seems to be no way to offer feedback.

"Provide feedback on features and performance to help determine what makes the final release" Oooh, you mean like putting the tabs on top despite complaints from scores of users and refusing to provide a setting to change it because those users are just wrong? Obviously users' opinions are of no concern to the development team.

I don't recommend this. Firefox is supposed to be free and open, and independent. The latest version from Mozilla, for Mac, is 42.0. But Version 44.0a2 (which I downloaded from Macupdate) is something quite different. My Sophos antivirus detected a PUA (potentially unwanted application) associated with it, and this could very well be that automatic Yahoo link, making Yahoo the default browser.. This is sneaky and unpleasant. Avoid Version 44.0a2. 42.0 which I downloaded direct from the Mozilla website, is fine.
