I'm proud to have been a Firefox user for over 20 years, and I've always managed to overcome any obstacles I've encountered.

My only request is that you allow the built-in browser VPN to be activated on desktop computers in Egypt.

Thank you very much for your efforts!

I'm now making Firefox my default browser because Safaari keeps crashing immediately after opening. That means I can't get into Safari to initiate importing my passwords into Firefox. How can I import them directly from within Firefox ?

Thanks Marty

I got a notice that an upgrade was available. I choose it and it wiped out all my bookmarks, my bookmark bar and all. Nothing works to recover, I tired going to previous version. That did not restore my system. I will quit using your product forever if you do not restore my settings.

Hi everyone, I am using a MacBook Air M3 with 8GB of RAM. Due to my workflow, I heavily utilize multiple windows simultaneously across both Brave and Firefox. Unfortunately, this heavy usage has caused my CPU and RAM demand to go through the roof.After doing some research, I was advised to switch back to Safari as my default browser to conserve system resources, and to use other browsers only as secondary tools.

To make this transition work, I need to prevent Firefox from automatically launching every time I start up my laptop. I do not want Firefox to open until I explicitly choose to launch it myself. I have searched through every conceivable setting, option menu, and help file, but I cannot find a solution to this basic issue. If I cannot find a way to stop this auto-start behavior, I will be forced to uninstall Firefox altogether, which I would prefer to avoid.How can I definitively stop Firefox from opening automatically on system boot?

Thank you for your help.

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.

I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```

I am using Firefox Developer Edition version 154.0b5 (latest according to settings) and when I try double clicking or use ctrl + A, the url won't be selected (or parts of it if I try something selecting something specific). Double clicking doesn't work at all.

Is this a bug?
