Firefox Community Forum

To preface this, I am on MacOS.

I noticed a small delay before starting videos while I have my AirPods connected. There are a few scenarios where this delay does not exist: - Any other browser - Audio is actively playing elsewhere - Mic is in use (like a zoom meeting in the background, even when muted) - Audio is muted

I have tried safe-mode, reinstalling, and even messing with the config, to no avail. I know for sure this is isolated to Firefox, and I believe it's due to how audio devices are handled. I would rather my videos immediately play rather than wait for a "health" check from my connected device, even if there isn't audio for that time period.

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.

When I copy a post in X from Firefox into a text file, it loses formatting, but when I copy the same post in X from Edge into the text file, it keeps formatting. Why?

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.

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

im using firefox on ubuntu, version 139.0.4. when i browse the internet using firefox, every some time the toolbar and the search bar "freeze" - i am unable to click anything, from the url, to any of the buttons. it takes up to like 1/2 minutes for the search bar and the toolbar to work again. i never had this issue before, neither on ubuntu (and other linux distributions), nor on windows...

I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

can you give us the option to change the hotkeys/shortcuts please? is it possible for this to be an option for the future, I and I believe a lot of others switching from chrome to firefox would like the accessibility to change it as to what they're used to. Thank you very much for your time.

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?

I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

On the Save Page As dialog on Linux, how do I edit the choices of where to save?

The stock options are Home, Desktop, Documents, Downloads, Pictures, Videos, and + Other Locations.

I don't use most of these directories, but I do use two dozen others. Navigating to them using Other Locations is painfully slow; it would be ok if I could then save the location I've navigated to, but I haven't found a way to do that, and clicking one path element at a time for 6 element paths over and over gets old quickly.

Typing the path I want either nukes the default filename, or else it tries to match the filename string from the URL in the target directory, which doesn't show me existing directory contents.

Thanks for any clues...

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?
