This is basically a copy of what I put in the Ubuntu forum. The problem is the same, no matter where I post it.

Originally I was using Ubuntu 18.04 LTS.

I thought it would be good to update to GG (20.10) though I did briefly try FF (20.04).

As the install was done on an existing 18.04 version things remained the same for programs, book marks, etc.

Ok, now the crunch: I USE Firefox ""A LOT"". When it loads, there are...... 8 x 6 windows of FireFox and each of those have anywhere from one to ""THIRTY"" tabs loading.

Believe me: ""It worked!!""

I could use it, also run other tasks as well - though a VM was pushing it with the RAM. But the entire machine worked.

Now, I am lucky if FireFox loads at all. Let alone let me browse.

When it loads some of the window's tops are flashing. A screen shot does not really show this. (I tried)

All that has changed is the O/S from 18.04 and Firefox from (what ever it was) to 83.0

I don't want this to be a finger pointing exercise between Mozilla and Ubuntu. I would prefer it is helpful to all.

What have I tried? I've tried starting FireFox with all addons disabled. Still happens.

I am going to try to remember to (next time) launch FireFox from a Terminal and pipe the output to a file to look for things.

The machine I am using has shown it is well up to being able to have this running. I have had it working for a few years like this.

This post is (for now) to establish there is a problem. I will post more information when I get it, rather than waiting to get it then post, as I feel there are a lot of people who have very similar problems and I want it known: ""You are not alone!""


Now a bit of extra stuff.

Other things which are weird: When I am watching stuff - youtube for example - the playback is/WAS jerky. I hadn't touched anything in the settings.

After digging around, I discovered that I had to turn ""OFF"" the hardware acceleration for the graphics. Question: How did it get turned on? (Semi rhetorical)

I have a lot of local pages I open with passwords. When I load them the CPU load goes through the roof and nearly invariably the program just exits. No crash report.

Which is a good 50% of how it happens. The other 50% is the machine just locks up and I have to power it down.

I work in IT and multiple users are having this same issue. It seems to have started at the same time about a week ago. When clicking on Firefox, no window opens and the cursor begins to rapidly flicker or spin. There is no error message given. When checking Task Manager, there are multiple instances of Firefox running. Trying to "End Task" on each instance proves futile because it seems that they are constantly refreshing (which is probably why the cursor flickers). Trying to run the command "taskkill /f /im /firefox.exe" sometimes works and sometimes doesn't, even in Administrative mode. The only sure fire ways to get the cursor to stop flickering and/or close the program is to restart the machine or uninstall Firefox. However, if Firefox is clicked on again after restarting, it goes back to flickering and no window ever opens.

Things I've tried:

1. Using "End Task" in Task Manager

2. Running CMD and using taskkill /f /im /firefox.exe multiple times.

3. Restarting the machine.

4. Clearing ALL temp files from the machine.

5. Uninstalling and Reinstalling Firefox

6. Uninstalling, deleting Mozilla folders from Program Files, Program Files (x86), and Reinstalling

7. Checking to make sure Firefox is not blocked by the firewall or anti-virus.

8. Uninstalling, deleting Mozilla folders from Program Files and Program Files (x86), Deleting Profile data from AppData\Local\Mozilla\Firefox, then Reinstalling

Nothing seems to be working. Any ideas?

Firefox has opened successfully for years. Today, I double clicked on the icon, and it will not launch. I uninstalled and reinstalled it two three times and no luck. So I then tried performing the profile creation and got the following result.

Profile couldn’t be created. Probably the chosen folder isn’t writable. [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIToolkitProfileService.createProfile]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: chrome://mozapps/content/profile/createProfileWizard.js :: onFinish :: line 181" data: no]

Not sure how to solve this.

No matter how I close Firefox, (X, File->Exit, Menu->Exit), if I start it again it doesn't automatically restore the previous session.

If I click on "Menu->restore previous session" it does restore it.

Of course "Restore previous session" is enabled.

Why did it stop working, what changed?

this morning, I get the above error message when attempting to open ff. I was able to open ff from the start menu(windows 7 enterprise), but all of my bookmarks have disappeared. I had the system administrator attempt to restore my computer, with no results, then reinstalling ff. upon reinstall, I was able to open ff, but bookmarks were still missing. then, a ff update "esr" was run, and now I get the error msg above trying to open ff from anywhere. I cannot open ff at all to restore defaults or run in safe mode to fix.

I set google.com as my homepage and haven't had problems until today. When I opened Firefox, The Microsoft homepage opened. I tried refreshing Firefox, checked the URL in Properties, and looked for add-ons--no fixes. The refresh had no effect, there was no URL added to the firefox.exe in properties, and I have no add-ons that would cause this. I thought it could be a virus but the page seems to be a legitimate Microsoft site. If I click the home icon on the tool bar, I get to the correct page. I'd appreciate any suggestions you might have. Thanks

Firefox crashed on me yesterday (2 Dec 2018) and does not open at all now, so Safe Mode is not an option.

Have tried: (1) closing and restarting Firefox; (2) restarting computer (MacBook Pro, Mid 2014, OSX 10.13.6); and (3) trashing Firefox, emptying trash, and restarting computer again. No luck. Continue to get the same, "We're sorry. Firefox had a problem and crashed," error prompt.

Per the instructions at https://support.mozilla.org/en-US/kb/firefox-crashes-troubleshoot-prevent..., I am pasting my most recent Submitted Crash Report here: Crash ID: bp-550e8b76-0c74-487f-a901-7abc70181203

Any help would be appreciated.

Firefox won't open and only gives me the crash reporting window. I'm on a mac with mojave (this started about a week after that was installed). I have tried starting in safe mode, creating a new profile, and multiple fresh downloads and installs. Nothing works. This has been going on for a few weeks.

The last crash report only says "1543632621". Previous crash reports are similarly empty with only a number.
