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 134.0
New
- Firefox now supports touchpad hold gestures on Linux. This means that kinetic (momentum) scrolling can now be interrupted by placing two fingers on the touchpad.
- HEVC hardware support is implemented for Windows users.
Fixed
- Fixed an issue that started with macOS Sonoma where the emoji picker would open and immediately close when opened with the Cmd+Ctrl+Space shortcut.
- Thanks to research by Carlos Duarte do Nascimento (Chester) and :bintoro, and a patch by Carlos Duarte do Nascimento (Chester), we have been able to fix this universally for this shortcut and similar shortcuts going forward.
- Fixed an issue that started with macOS Sonoma where the emoji picker would also insert the character "e" in the selected text field/box when opening the emoji picker using the Fn+e shortcut.
- We have also fixed this for similar shortcuts using the Fn key.
Changed
- Firefox follows now the model HTML specification for transient user activation more closely. This change makes popup blocking less strict in cases where previous versions of Firefox were overly aggressive, reducing erroneous blocking prompts.

Version: 62.0
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.

Version: 44.0a2
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.
