When I custom installed to a different path,I didn't have the service installed,and when I encountered an update,I manually updated and restarted Firefox Brower,and I saw two uninstall lists in the control panel uninstall list.

When I forward or backward a video on Youtube, using J, L keys, arrow keys or mouse click, or pause & unpause, there is this fade in effect on the sound. The volume isn't constant. Volume starts at low and it gradually increases. I don't have this issue on any other browser or application.

Hi all, I'm using Firefox 140.0.4 (64-bit) on Debian Trixie and I'm getting a weird behavior with the auto-complete functionality of the address bar.

If I type the first character the address gets auto filled (see 20250711_First-character-auto-fill-working.png attachment), then if I type the second character the auto filled result disappears (see 20250711_Second-character-auto-fill-NOT-working.png).

I've tried any search option combination, but results doesn't change. At the moment I'm using for the address bar just "Browsing history" (see 20250711_Address-bar-settings.png).

The correct behavior would be, as in the past, that new characters confirming the address would leave things as they are. Do you have any suggestion on how to restore the original behavior?

Many thanks,

Raoul

I signed up & paid for Mozilla Monitoring Premium. I get monthly reports from then, but when I click on "automatically delete data from brokers," I'm asked to sign up for Premium again. Please help.

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

Recently switched from Chrome and in Chrome I would open my "Other Bookmarks" folder and middle click a bunch of bookmarks which would open them up in a new tab without switching to that tab or closing the "Other bookmarks" folder.

Is there a way I can replicate this on Firefox? Because at the moment, middle clicking the bookmarks does nothing. This is not about the bookmarks bar at the top.

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

I used to use Firefox as my standard browser until this issue occurred some years ago. I can no longer add, edit, or see any bookmarks I previously had. When I start the browser, I'm met with an error message (see below), which then sends me to the site in the image below. The title roughly translates to: "The System for Bookmarks and Browser History is Non-Functional". I've tried following these steps in the past with no change regarding this issue, and I've had to switch back to Chrome. I've also tried uninstalling and reinstalling Firefox, but the issue persists.

Has anyone else encountered this?

Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

I have loaded Messenger onto my new computer as well as Firefox. When I go to Messenger the Voice and Video icons at the top right are greyed and when hovering over the icons, I get a message that video calling etc is not supported. i had no trouble on my other computer but am not sure how to activate the video and voice options. Can you please help me solve this issue. Thank you

Summary - Firefox crashes repeatedly. yesterday, I decided to switch to Firefox after using Chrome for a while. it worked fine and I synced my data from Chrome. today, at some point I noticed Firefox is no longer open in my taskbar. I decided to reopen it - it crashed. since that moment it has never worked again. I tried launching it in safe mode (firefox.exe -safe-mode), didn't work. tried reinstalling it, didn't work. manually deleted the files from C:\Program Files and AppData, installed Firefox again, didn't work. reinstalled gpu drivers, didn't work. sfc /scannow-ed, you guessed it - still crashes. what else could I possibly try? please help.
