Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

I have only one instance of Firefox to run.

How can I correct my installation so it does not think something else is running/updating Firefox?

Thanks,

Craig

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

After the last update a couple days ago Firefox does not come up correctly. Search doesn't work. Duck Duck Go seems to be the default search engine and Google is missing from the selection list when the left mouse button is pushed. I really don't know how to describe the problem. It does come up in troubleshoot mode more-or-less correctly. Something odd happened during the update. A screen came up with some sort of message about having run into some sort of odd problem and that it would have to stop and restart the process, which it did. Hasn't worked properly since.

I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N

I "create a new profile" days ago what I first received the notice to update. It seem to work except when I click on a url to view. I received instead the notice that I am in the old firefox and to "Update". I did again and it seem to work until I clicked a url to view and again received a notice to "update by creating a profile.

It's very frustrating - Now I can't open firefox at all. It wants me to "fix it" or create a new profile"

How should I fix the frozen browser. Firefox updated ok from another user account on this computer, though Firefox has always updated for all accounts on the computer when updated from any of the accounts. The installer tool got caught in a loop to install until it froze the browser on the third retry. What should I do?

Google Play says I need to update Firefox, but whenever I try it says it can't update. My OS and Firefox versions are in the attached screeshots. I'm unsure as to how I should proceed.

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

My computer downloads your updates over and over again, tying up my computer--none of the downloads ever loads This problem is can only be fixed by pull the plug restarts as these downloads will not stop until I do this

I use Firefox on a ASUS Vivobook running Windows 11. On April 1, it tried to update to version 137.0, but failed and led me into a update loop of sorts. I had to re-install Firefox just to force an update on it, and that worked for a bit. Just today, it decided to update... and led me into ANOTHER update loop, and it's saying that the "install failed" when I check the update history.

Is anybody else experiencing this bug, and is there a way to fix it?

I recently updated my wife's computer to an Apple Mac Mini M4 running iOS 15.4. Everything seemed to be working fine including Firefox until yesterday when Firefox update box popped up. She did as she normally has for years of using Firefox and clicked the restart for update button . FF restarted and popped up with 2 dialog boxes one asking to check network for there devices which she click "Don't Allow", she only uses that computer no smart phone etc. Then a second dialog box asking for an admin login and password to install something else I put in my admin login and password clicked continue it doesn't seem to do anything except lock up Firefox to the point I have had to re-install her user from a time machine backup 2 times in 2 days. I tried installing a new copy of Firefox that will launch the issue is she's used Firefox for probably 10 yrs so there are ten years of bookmarks and logins and passwords saved in the original copy of Firefox that will no longer boot unless I do a complete user re-install from a time machine backup.

Please help, how can I fix this problem?
