Followed unstall and trying to remove remaining folders, data from computer.

I cannot del these folders, etc despite being admin mode or from command line.

whats next.

I want to do a fresh install of Firefox but wont install firefox again if I have to an computer reimage.

When I watch videos (reels) on Facebook, and sometimes on YouTube, I share a video either to messenger or my page, the whole string of videos I have already watched goes back to the beginning of the string everytime. Only Firefox does this. I have 3 other browsers that work fine, but I prefer Firefox of course.

I'd appreciate a fix for this, Thanks

Anyone use LastPass? Do YOU have any hair left? How do I put that extension up at the top. Where my red arrow points? ALSO......

Hi,

On the "Your Firefox has updated" page, I recently found out that in addition to Firefox Sync, you can also create a backup in the form of a local file. When I try to follow the instructions on the support page for the function (here I get stuck. For some reason I am only allowed to choose a file to restore my data, but I am not allowed to create a new backup. I have tried refreshing Firefox and even creating a new profile, but both have the same issue. I am not seeing a "manage backup" button either (see screenshot).

It's not the end of the world thanks to Firefox Sync, but I would like to get it working as a nice backup :)

Thanks in advance for any help you guys can give me!

How do I get rid of it? I have closed it but it returns the next time I try to enter firefox

On updating to linux mint 22.3 - cannot type anything in firefox in address box, search and primary password or anywhere else within firefox - have uninstalled & reinstalled but nothing happens

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.

Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

Something's wrong with my Tumblr. When Firefox crashed before it updated, my Tumblr has completely broke (It won't show any notifcations that someone posted, the activity is stuck at 2 and community at 6). PLEASE HELP

Hi I just saw the new info on backing up my Firefox data. It sounded good, so I tried it. However I do not see 'Manage Backup'. Instead it asks 'Choose backup file'. I have never knowingly backed up Firefox, so I do not know where this backupfile is located... How can I find it? How do I create a new backup file? Many thanks An

I hover over bookmark folder, they expand, and the links the folder contains work. (Or) now 80 percent of the time, I hover over the bookmark folder, they don't expand, so I click on the folder to expand it, and 90 percent of the time, the links in the folder do nothing when clicked on. They won't even get highlighted, (selected) I restart firefox, and all works again, for about 10 seconds, and problem occurs again. It goes without saying it gets real frustrating restarting firefox over and over and over again to use another bookmark. I've never experienced this before. This only happens for me on firefox for Linux Mint 22.1. Firefox on windows 11 does not exhibit this problem. Please help, thanks. Cheers...

I went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

I moved some old folders to Trash but they won't delete. I've changed the retention policy, tried to delete individual emails, repaired the folders, restarted FireFox many times, but they're still in Trash. How can I permanently get rid of them? Thanks

Ever since Firefox updated (to 147.0, I assume), I can no longer get ChatGPT to work. It does nothing when I click on "Log in" (I have a ChatGPT account), and the up arrow that you hit (or enter button) after asking a question does nothing (and the up arrow stays greyed out even while you are typing the question). I can use ChatGPT just fine on my Safari browser and iPhone. I used my iPhone ChatGPT to take me through steps to help, and it had me do several things (all of which did not work). These included: 1) refreshing the page/restarting; 2) open chat.openai.com, clicked lock icon and clicked "clear cookies and site data" and reloaded the page; 3) did same and clicked on the shield icon and toggled off "enhanced tracking protection"; 4) Went to file and "new private window", then chat.openai.com; 5) went to "about:support" in Firefox and clicked "refresh Firefox"; 6) Went to Firefox Settings, then Privacy & Security, then Permissions, then Block pop-up windows, then clicked exceptions and added "https://chat.openai.com"; 7) Then to Firefox Settings, then Privacy & Security, then Cookies and Site data, then manage exceptions, then added also "https://openai.com"; 8) Then changed enhanced tracking protection to Custom and unchecked cookies (cross-site tracking cookies) and restarted Firefox (I have since rechecked the box); 9) When I log into Firefox, it was showing a banner that read "Your privacy matters. Firefox now securely routes your DNS requests whenever possible to a partner service to protect you while you browse." Chat said to click "Disable" for this.; 10) After refreshing Firefox I chose (the 2nd time) "Restore only the ones you want" and opened a new tab. 11) At one point, I hit "Log in" for ChatGPT and the screen went slightly blurry and a new small rounded rectangular box (about 3 inches long) popped up, and Chat told me to hit the "X" to close that box, it then said to right-click on "Log In', and to choose "open link in new tab", but that option was not available. Chat says Firefox is still failing to load the embedded login frame, even after refresh. 12) I logged into "https://chat.openai.com/auth/login, and that still didn't work in Firefox, either. 13) Finally, I changed to Safari and successfully logged in. But I prefer Firefox as my main browser and want ChatGPT to work! I've even tried adding it to my sidebar (the new feature), and the same problems are occurring. It won't let me log in, and I can't ask it any questions. Help!  :)
