Firefox Community Forum

I signed onto my parents computer that was assigned to a school district and now everytime I open firefox on any of my devices their website keeps popping up. I've signed out of their computer and have tried deleting and reopening my account, and nothing seems to work.

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

For a week my pinned tabs are lost every time I open Firefox. I have checked my settings, they were the same as always. I have de-selected them, closed and re-opened firefox, selected them again, closed and re-opened again, pinned my tabs again. Then closed and re-opened firefox and still they are not there. I have done this multiple time with the same results. This seems to have started after the last update.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

This is not the first time you have sent an email to me indicating I should "View all sites where your info is exposed", and each time I receive your emails the sites you suggest are sites I have never seen before, let alone logged into with a password.

I use a Password Organizer Book, with all of my logins and passwords for each site I use. I do not use a password app, and have NEVER used a password app. Each time I go to the website you suggest, It's always a site I have never seen before so it would be impossible to login and change the password. I always check my Password Organizer Book to make sure.

I don't know what you want me to do since I cannot login to the website you are suggesting. Is there action I should be taking? I don't know what it would be, but if you know please let me know.

The AI tab thing is a problem for me for multiple reasons. I found various articles about how to turn it off. They pointed to the following setting: In about:config set the setting "browser.tabs.groups.smart.enabled" to false, and then restart Firefox.

However, when I do that, and then immediately go back to about:Config to check the setting, it has changed itself back to "true".

Other settings accept and keep permanent changes. This means that I'm not forgetting to save the change or anything. Just this one setting (which turns off something causing me problems) refuses to actually stay set.

I see the answer to this question https://support.mozilla.org/en-US/questions/1509077 and tried looking there. There is a completed study called "Smart Tab Groups Rollout", but since it is in the "Completed Studies" group, I cannot remove it.

I updated to Firefox 141.0 and now Google Maps is not working correctly. When I look for directions the map does not show the route. If I go to street view I get a black screen. Google maps is working fine on Edge or Google on the same pc.

Whenever I use Google Meet in the Firefox browser, it works well at first people can hear me. However, for a few seconds, my microphone suddenly cuts out, and I have to raise my voice for it to work again. My microphone remains enabled and does not disconnect when the audio cuts out, but people are still unable to hear me. I have already set my microphone to 'Always Allow' instead of 'Allow Temporarily, but the problem persists.Can anyone help me with this

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

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.

I'm currently using version version 141.0.3. Every time I've upgraded the version, there's been other problems with video playback on certain websites. Regardless, I can't read a number of pages of interesting articles because of this browser versions' adblocker which I can't lower or allow social media posts if I want to. My harddrive is almost maxxed out as Windows 10 occupied the majority.

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

I am trying to preserve my POCKET data before it all goes away. Mozilla responded to my email requesting data but when I opened the link I got this message that "the provided token has expired : despite it being less than 24 hours. Plus a lot of other characters meaningless to me. What can I do now?

This XML file does not appear to have any style information associated with it. The document tree is shown below. <Error> ExpiredToken <Message>The provided token has expired.</Message> <Token-0>

The issue is very simple. When loading into the roblox website, the page becomes almost completely empty aside from the buttons at the top like Charts, Marketplace and the roblox icon at the top left. All of which do nothing when pressed.

The weird thing is that it works completely fine on an incognito tab..? Now I noticed something similar happening with other roblox's websites, where some parts of the site would break in very similar ways, but I thought nothing of it cause it didn't affect me too much. But after the new update, it extends to everything, not just one sub-page of roblox, the entire website is like this.

I removed my extensions and restarted my browser to see if that would fix anything but it didn't help.
