Firefox updated automatically. No bookmarks or history??? I cannot find anything. This is my old Windows 10 computer. Have bookmarks on Windows 11 computer. Afraid of updates. any help?

I recently upgraded from Windows 10 to Windows 11. I was under the impression that my bookmarks would be saved to my Mozilla account and I could then log in on the new computer and the bookmarks would come over also. Is this accurate or will I have to go about recovering my bookmarks a different way?

As of now when I log into Mozilla I get a message at the top saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. I clicked Learn more and tried the troubleshooting options, but no luck in fixing the message or issue. Thanks for your help.

Several weeks ago, Mozilla completely reset my Firefox. Removed my addons, reset my settings in about

config. I had previously changed a lot of things, specifically stopped all videos and things moving on my page. I searched the net, and changed a few things, but I still have things moving on my pages. Thanks, Mozilla, Brave is looking better everyday. Win7 115.30 oesr I am not happy. How do I send a message right to Mozilla, Hidden and impossible.

The mailto option for AOL Mail does not produce the correct URL -- it simply opens AOL email but does not create a new mail with the subject link I wish to send like other mail programs. Can this be sent to support to correct please?

Note that I have tried to correct the URL command but have been blocked at all suggest modification points.

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

My desktop (Windows 10) Firefox just updated to 145.0.1 and the right-click menu is defective. It has a bunch of blank lines, the only options listed are search DuckDuckGo, translate, and use AI. This ruins my browsing experience, since I can no longer open links in new tabs which is my favorite way of looking at newspaper home pages.

Hello, I'm using Gitlab. When I open a file, then click to the "copy file contents" button, it copies but even the file designed and filled one under the other, the copied content is side by side. When I do the same thing in Chrome, there is no problem. Could you please fix this? Yours faithfully.

Hi, there.

After performing the most recent Firefox update, I was greeted with the "create a new profile prompt", rather than having it open my old one. When going to "about:profiles", ALL FILES in the Root Directory of my old, default profile have the same date as the update, or after. Not a single file is older than that and all my history and bookmarks are gone. The option "Restore Previous Session" was not shown after the update.

PLEASE HELP!!

Thank you.

PS: This happened on a Macbook Pro. All other profiles are the same as they were before the update, having kept all history and bookmarks.

After trying suggested "fixes" still unable to get bookmarks restored on my Firefox account, and can't add any new ones either. Should I reinstall Firefox?

I am using Pop OS. Videos are not playing in firefox. In youtube it shows loading infinitly. In reddit all videos become green. I tried playing a downloaded video it also become green. These are only happening in integrated mode. If I use hybrid graphics mode all works good. I attached the about:support page and about:config page.

about:config page link about:support page

These files are taken in integrated graphics mode.

I keep getting sporadic crashes, and sometimes a tab crash (particularly on maps.google.com). I have the latest updates to all my software. What can I do to help prevent these crashes?
