Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

ich bekomme die auforderung in firefox meinen AdBlock zu deinstallieren mein AdBlock ist aber deinstalliert was will mir diese meldung sagen es gibt auch noch einen AdBlock Plus aber den habe ich garnicht installiert

Die blaue Titelleiste inklusive dem X zum Schließen des FF ist ständig weg und kann nur mit 2x FN11 drücken wieder angezeigt werden. Alle Einstellungen sind korrekt und mehrfach überprüft. Auch jetzt, während des Schreibens dieser Frage, ist die Titelleiste weg. Sieht nach einem wirklich nervigen BUG aus.

out of nowhere my firefox bookmarks no longer appear. I am getting the following msg

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.

In an attempt to fix this problem, I have done the following:

• closed the browser and re-opened it
• rebooted my computer
• reinstalled my security software
• uninstalled firefox
• Reinstalled firefox

None of these steps have fixed the problem??????

Any ideas would be appreciated!

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?

This is the message I get when I try to access my Bookmarks: "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." I have already tried to find out from Microsoft if their latest reinstallation of Office Professional could have caused the problem. They say they have nothing to do with Firefox. How can I get my Bookmarks and History back?

I live in Northern Ireland which is part of the United Kingdom. The full name of the UK is as follows "The United Kingdom of Great Britain and Northern Ireland". When I select my country as UK, Firefox changes it to GB. Northern Irland is not in GB. Great Britain consists of England, Scotland and Wales.

bold text I have been given a new firefox and this is so far out of what i need that i am about ready to call it quits -- where is my toolbar? All i have is some bookmark nonsense that has nothing to do with me or what i search for --

I have a rather strange problem and I'm not sure this is the right topic. I generally use my computer on and off all day and I never lock it until the evening when I turn it off. I went out for several hours today and when I came back there was a new version of Firefox installed. When I opened Firefox I realized it was a new version because it would not let me logon until I had completed a profile. My old version never did this. In addition all of my saved passwords had disappeared as well as my bookmarks. I'm using a Dell laptop running Win 11, about 2 years old. I don't understand how this could happen. There was no one here while I was out. I looked to see if there was a saved profile but only the one in use showed up. The current version appears to be 145.0.1. One thing that might have something to do with it. I might have been asked yesterday if I wanted to synch firefox on my computers but I'm not sure how I answered this (I'm almost 90 and my memory is a bit imperfect).

I do have Firefox on a second desktop which is running Win 10. Is it possible to use that profile. That computer has not been turned on since this happebd and is currently asleep. Any help or suggestions will really be appreciated!

Why are all GetResponse redirects causing 404 errors in Firefox but not in Google Chrome?

Here is a primary link that feeds GetResponse https://app.getresponse.com/click.html?x=a62b&co=IfVvoP&lc=hXaPFo&mc=9F&s=B0OSZKW&u=QELup&z=EhPrtjL& if you want to see for yourself.

I have no idea what happened, but i was changing settings on my PC and suddenly i was logged out and all my browser data, bookmarks, passwords etc were gone. I dont know if i clicked the wrong button or what but everything is gone. I still have my data on my phone, and can access my passwords and such but I dont know how to get the browser data from my phone onto my PC

Please, I have many important passwords and bookmarks that I need to be able to recover.

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.
