We have a client that used to run on local computers running the latest ESR version, they recently changed to a terminal server environment and during the setup 59.0.1 made it onto their new setup. Multiple issues have arisen that were not present on the old system and we need to move them back to the ESR version on the terminal server environment. I read online that you cannot just directly import any profile versions 55.0 and up to earlier versions so I am asking if I can instead use a mozilla account to sync over their data instead without causing a catastrophe, and if anyone happens to know what I might expect afterwards if this could potentially work.

Started w/FF 29 something.on Win XP (Home) SP3

Verified w/Task manager and PS that there is no other instance of FF. Occurs only in my profile, administrator and other users do not get this message.

The fix I used last time (uninstalling completely and reinstalling in Safe Mode) ***did not work in this instance***.

Firefox now version 33.1.1, all seems up to date but I still get that message. When I open Help > About it says I am at version 33.1.1 and to restart to upgrade...

Any ideas greatly appreciated.

Since upgrading to the latest version I am trying to find replacements for the newly disabled add-ons. I first tried this on Friday the 8th. The same problem has been happening all weekend including today and I imagine since I installed this version. The exact wording is downloading and verifying add-on.

Overnight (I changed nothing, but microsoft rebooted my computer and I don't see any new files installed or updates) Firefox will not work. I can see it start up in task manager (two processes) but within 1 second both are gone. I've tried uninstalling and reinstalling firefox. Same problem. This is Windows 10 v 1909. Firefox will not start in safe mode. I cannot find any crash files (in the past month).

I just upgraded to Firefox 77, x64, Windows 10 2004.

Firefox 76 already broke LockWise - https://support.mozilla.org/en-US/questions/1287008

Now Firefox 77 breaks 99% of all websites. (See attached screenshot.) www.example.com www.google.com www.wikipedia.org etc

Somehow, support.mozilla.org works, UNTIL I try to log in.

I've tried incognito mode, safe mode, etc. When I change charset of the page, the text displays differently, but it's still a useless mishmash.

--- BUT --- when I open developer tools, click the HTML request and click the Response tab, the HTML renders correctly there.

Recently I've been having trouble with the dropdown menus in Firefox, such as the History and Bookmarks menu in the tool bar and the right-click menu. Intermittently when I open the menus they close within a second or two without me doing anything. This only happens in the Firefox window, all of my other apps and browsers are fine.

I'm running on a Macbook Pro with OSX 10.15.1 and Firefox 70.0.1. I've restarted Firefox and it fixes the problem for a short time then the problem returns. I've cleared my History, including Caches and Cookies, reinstalled Firefox, restarted my computer and tried disabling my add-ons. The issue keeps coming back.

I completely removed Firefox and deleted all folders. After installing Firefox fresh, Firefox sees that it was previously installed?? "Looks like you've reinstalled Firefox. Want us to clean it up for a fresh, like-new experience?"

I uninstalled Firefox (supposedly) "completely" using the guide here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

Why does the new install Firefox recognize that it was previously installed? Uninstall tool needs to uninstall Firefox COMPLETELY. Since it lies, can someone help tell me what is the appropriate steps for COMPLETE removal?

Firefox magically stopped working tonight. Based on reading help files and past forum posts, here are things I've tried with no luck:

Note: Running Windows 7

- Rebooted (of course) - Uninstalled through the task manager and reinstalled. - Uninstalled and deleted the C:/Program Files/Mozilla Firefox directory and reinstalled - Once reinstalled, attempted to start in safe mode via holding down Shift while loading - Attempted to start in safe mode by attempting to type many things in the run window:

        Firefox -safe-mode
        Firefox /safe
        "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

- Attempted to add a new profile by typing in the Run window (after reinstalling):

        "C:\Program Files\Mozilla Firefox\firefox.exe" -P 

None of these solutions have had any results. No matter what I do, no Firefox related windows will come up and I get no error messages of any kind. Most of the time I at least get a busy cursor for a second and a firefox.exe process will start. I've kept the Task Manager open through most of the attempts and killed firefox.exe between all different attempts. Most everything I do will still open a process (I have two of them still running right now) and I kill all of them in between attempts, not to mention shutting down. I even did a hard battery pull on my laptop just to be sure. I'm not making any headway. If I could at least get an error message that would be nice, but I get nothing at all. Any other suggestions?

Ever since Firefox nightly did an update a few days ago, I have been unable to run it from the normal shortcut. I had to make a copy of the exe and rename it and only then would it work from the renamed file. If I click a link in Thunderbird, for example it still looks for Firefox.exe and not the renamed file. If I change the tile to Firefox.exe.bak so that only Firefox1.exe is accessible, I still have to run it manually from that new file name rather than the default. This is a new install of Windows 7 x64 Ultimate and this is the only time I have ever had problems with nightly. Now, when I restart the browser, it downloads a new firefox.exe and the error returns. I would rather try and fix the problem than remove all traces of it then reinstall, that would be like ignoring the problem and starting over which won't 'fix' the error that others might have.

I have a customer who is unable to browse to any websites after version 81.0.2 was installed. They are also unable to open Options and other Menu items. Only Toolbar Menu item that worked was Help > About. I have tried using Firefox in Safe Mode, I have refreshed Firefox, and I have renamed the AppData > Roaming > Mozilla folder forcing it to create a brand new user profile. The only security programs running are Windows Defender. Chrome and Edge work fine, so customer will use one of those until Firefox is fixed.
