On certain websites , the audio and video still auto play even though the option, "AutoPlay" is blocked for both audio and video.

Please see the attached screenshot which shows that auto play is blocked, it is circled in red. While the video has auto played, circled in orange with a timestamp of 17 seconds being played prior to it being manually stopped.

Please fix this issue.

The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?

After last upgrade, I restored an earlier profile to RESTORE my bookmarks and passwords.

I set my old profile as DEFAULT.

YET NOW, I have the highly annoying problem that when I open a link from my email, it opens in the profile-release new version.... I then again do not have access to passwords and bookmarks.

Mozilla Firefox should address these issues, rather than have MILLIONS of people individually trying to fix the problems that the latest release caused.

I'm afraid to close my browser windows or even restart PC like I often do; I'm afraid I'll have to waste another 6 hours (like yesterday) trying to restore the profile, bookmarks and passwords.

Firefox just introduced a cool feature that lets us set custom wallpapers on the home screen—love it! But whenever I try using pictures from my personal library, they don’t fit properly and end up getting cropped. Resizing doesn’t help either, since making the image smaller just ruins the quality.

So, is there a specific format I should be using? Like, does it need to be JPEG only, or will any file type work? And if any format is fine, what’s the ideal one for the best results? I couldn’t find anything in the settings or help pages about this.

Firefox 139.0.4 changed behavior of text search (find-in-page). It now opens closed accordions and finds text in the <details> text (which it did not do prior to this update). This really breaks my webpage. I think this was changed for compatibility with Chromium.

Is there a config setting to change this behavior? Alternatively, can I change the accordion html so that Firefox will not search the <details>? (These are my private webpages, so I can edit them.)

This problem just began today on my Win 11 laptop. Firefox is current - 139.0.4. Win 11 is current. No new software has been installed. Firefox hangs up and will not move. Task manager shows FF is consuming more than 90% of my 16GB memory. I must end the FF task to get up and running again.

1.The browser is closed 2.Looking at the task manager, there are still two browser processes (firefox.exe) present and they together take up about 3GB of memory 3.These two processes have no I/O reads and writes. 4.These two processes cannot be concluded. I've tried CMD, Powshell, XueTr, etc., but none of them can free up the memory space occupied by these two processes.

Hello! I wanted to see if there was a way to have sent tabs be automatically opened on Firefox mobile. Searching "Automatically open sent tabs on Firefox mobile" gives help guides on syncing and not how to automatically open links sent through the feature.

Instead of having to open any number of notifications I would much prefer the tabs automatically populating the tabs browser. I currently send from PC/iOS-mobile to Android-mobile but will be switching to a second iOS-mobile device soon.

Thank you
