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 just used pacman to update to the latest Firefox, but the tab crashed each time I open a new web page ( I can open settings, about:xxx and etc... ). I tried Troubleshoot Firefox crashes and it did not crash in troubleshoot mode. Then I tried extensions, themes and hardware acceleration issues to solve common Firefox problems https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems but non of these options solved the problem. I disabled all extensions, themes and hardware acceleration, and it reported the same error.

First, I just had a major system crash, had to re-install Linux Mint and through my own stupidity, relied on the wrong backups for my firefox configuration. So I lost my Firefox 52 install with all of my extensions (that still worked). Now, I'm running v. 57 Quantum, and a few things aren't working correctly.

First, the MAJOR problem: when I open a link from a bookmark, it's clobbering an existing tab that I was using (that's why it was open, obviously). That is completely unsat and can not be allowed to continue. How do I correct this? I can't find the option under settings-->tabs to fix this problem.

Second issue (major annoyance): I can no longer create a bookmark directly in a bookmark folder on the bookmark toolbar. I used to be able to open that bookmark folder, and the first option was to bookmark the currently open tab. That option has vanished, and i use that all the time. How do I restore that?

Actually, one more issue: I have two tabs that are pinned and are supposed to be protected (i.e., nothing can clobber them, and I can't close them without deliberately turning the protection off (context menu right-clicking on tab). I need that back, because for some reason, firefox thinks it's ok to open a bookmark in those tabs, too, when it most definitely is NOT ok.

Hi All, I have only recently installed Firefox for a specific purpose, have no plugins installed, just the basic program with about 3 bookmarks, that's it. Was all working OK until yesterday when it just wont boot. I have tried everything I can think of, so far:

Have tried removing (using app cleaner) and re installing - No joy

Tried going to profile manager through terminal - deleted and created profiles but still no joy

Tried deleting app again with app cleaner and reinstalling previous version - no go

Tried starting app in safe mode (shift key) - no go.

Looking for suggestions as I need to use Firefox for just 1 old website that seems to not work on anything else!

I'm running a Macbook pro Early 2015, Mojave 10.14.6

I have checked: Application support (on every user) & Cache (on every user)

I don't know what's up, I also reinstalled Firefox after deleting everything related to it and I just don't know.

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.

The only security programs running are Windows Defender. Chrome and Edge work fine, so customer will use one of those until Firefox is fixed.

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.

As the question says. I updated my Mac (2018 MacBook Pro) to the most recent OS (Catalina), I've uninstalled and reinstalled Firefox like 6 times, cleared my trash and any and all Firefox files, and deleted all profiles, made a new default one, and then deleted that one when it still wouldn't start, and restarted my laptop more than once. I cannot seem to get it to start no matter what I do! I've tried every fix I can find online. Every time I try to launch Firefox, it appears in the dash for a second and immediately shuts down. Trying to start in Safe Mode doesn't work either. Firefox used to work, but then I force quit it *once* because I was quitting all applications I wasn't using. Now it won't work at all no matter what I do. How do I fix this?

So I generally keep Firefox up to date, letting the system manage itself, but this time I have had to disable this update. When I update, either through the automatic updates, or even from a fresh install of 75 (or beta 76) the browser starts, I see the lovely new address bar, albeit blank, and the browser just hangs right there. I can type in the nifty new bar, but nothing happens, no browsing to a site, no opening configs, nothing.

I have this issue on windows 7, 8 and 10 machines, so it's not an OS issue.

When an update does happen it chews up my profiles too and I have to end up rebuilding those. Only when I go back to 74 does Firefox work again.

I'm at a bit of a loss here.

I have been using firefox for years and am very happy with it. I have a Dell optiplex 7010 desktop. I am running Ubuntu 18.04.4 LTS. I do not have a firewall turned on. Apparently, my desktop browser was updated to Firefox 78.0.1 (64-bit) on 7-1-2020. Since that time, I have been unable to access any websites from Firefox including mozilla.org. I am connected through WiFi. After downloading the Opera browser I have been able to access any website with no problems. I read community troubleshooting on this issue and tried various fixes including turning off IPv6. I read the community article about turning off my personal firewall. I was unaware of using any firewall so I installed Gufw Firewall 18.04.0. Running this program shows my firewall status is "OFF". I checked my AT&T modem and could not find any firewall settings that specifically mentioned Firefox. I would like to continue using Firefox since I use it on my phone and laptop also use it.

My laptop is a Dell Vostro 1520 running Ubuntu 18.04.2 LTS 64 bit. It also accesses the internet through the same WiFi. It currently has no problems loading web sites with Firefox version 78.0.1

Please help.
