Another Windows update, another instance of Firefox bookmarks being inaccessible :-( "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." Now what? What are we supposed to do? Is Firefox doing anything about this problem, since it's become a regular occurrence? Help, please!

When the YouTube shorts tab is open, if I want to open another tab, it immediately starts scrolling. When a shorts show starts, I click the "plus" button and it immediately scrolls down. I hope you get the idea.

Hey there,

Whenever I use the picture in picture feature on Firefox to watch something while doing other things,it has randomly gained these black bars on the side of the image and I can't work out what is different? If this is a quick fix, I haven't been able to find it, sorry!

Thank you in advance!

Can one remove the green dot update notification on pinned tabs without having to create an bespoke css file? Think some sites spoof this to get you to click on them.

As I said in the subject, my sidebar moved to the right side of the screen, and now takes up over half of the entire screen. I think this can be fixed in settings, but I don't know how to do that. Can anyone help me with this problem?

I updated to version 146 today on Windows 10 and had to use administrator credentials. I have Mozilla Maintenance Service previously installed. I tried uninstalling MMS and then re-installed FF using full installer and selecting the custom option to install MMS. I cannot see the option in Settings..General 'Use a background service to install updates' (Screenshot attached) How can I fix this issue which has been present for some time?

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?

I have an old Laptop which works perfectly for what I need, and I use Firefox for my Browser.

I had to shutdown my Laptop and everything seemed Ok on reboot. However, I can no longer access my Gmail account as I apparently "need Chrome" to get access...?

Do I? If so - how do I get it installed on my system?

Thank you

I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?

Hello, I just updated to Firefox version 146, and now the bookmarks and history in the sidebar are no longer visible because the background is yellow-green and the text is white...so, invisible!

I hope you will fix this quickly with a new update, as it's a real problem.

Thank you in advance. Sincerely,

The last couple of weeks or so (as of 121025), using Firefox is very slow. Is this another Firefox update issue, or Microsoft update issue, Norton update issue or a combination of different updates that aren't working together as has happened many times over the last few years.

Any known solutions to this new problem?

Thanks

Ron

I need step by step instructions in order to make the changes that Mozilla/Firefox wants me to do. I have also been having medical issues which is affecting me mentally. Right now I am totally confused, and I don't know what to do.
