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.

I've been experiencing too much crashes on Firefox 75.0, downloaded from Mozilla, not the one that comes with Linux. I'm running on debian9 on Qubes OS but I also experienced crashes on Ubuntu 19.

It happens mainly when I switch tabs. I'm asked to restart. I already submitted hundreads of crash reports, hope you guys are taking a look. However this have been happening since january I guess. And it's getting worse.

Sometimes the crash will happen again and again if I try to reload the tab. I have to close the tab and open it again so it won't crash.

Please help, I love firefox, don't want to use another browser.

Here are a few ones:

I opened Firefox this morning and used it for about half an hour. I can't remember why I closed it (or IF I closed it) but when I attempted to reopen I got a blank screen attempting to open my Yahoo homepage, but nothing happened. I force quit and attempted to reopen and nothing happened. I'm on a iMac and the icon on the deck just keeps bouncing. I haven't changed anything and it worked fine earlier. Is there a system problem? Thanks.

I have downloaded the "latest version" of Firefox to my Mac which is running macOS Catalina Version 10.15.3. After 7-10 days Firefox will not "open". I then uninstall it, and reinstall it. Again it works for 7-10 days then will not open at all. I have gone through these install / uninstall processes at least 10 times. Yet after 7-10 days Firefox will not open. What is causing this, and how can I keep Firefox working continuously on my Mac? Thank You. WA

P.S. - I am sending this question from a Windows 10 computer because I cannot open Firefox on my Mac.

Hello, The day before Firefox just stopped working, I can start the program but its completely disfunctional. Menu bars roll down, but if I click on anything, nothing happens, like if the buttons were dead. External buttons like "open file", "save page" do pop up, but not internal ones, like Troubleshooting info, probably because they would also open as a Tab, which doesnt function. I can type into the search bar, shows the url, even seems to have access to search suggestion from Google, but nothing happens at all. I tried everything I could find, reset Firefox through safe mode (also doesnt work better), completely deleted and reinstalled everything, including all data folders, checked my Antivirus (Norton... yes, could be bad), but I even deinstalled antivirus. Also tried "netsh winsock reset" https://support.mozilla.org/en-US/questions/1021896 Im out of options. Thanks for Help!

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.

Every time I open Firefox it brings up a screen as if I am a brand new user starting out for the very first time. The disk image in my downloads folder has long since been deleted, so I'm pretty sure it's not running from that. I went and looked at "application binary" and it gave me a headache, plus there was no indication in the prior "support" replies of what the changes I might or might not observe therein would mean, so I was unmotivated to keep turning Firefox off and on and then checking to see if any of the characters in the very long text string had changed. I seem to have about 10 profiles, none of which have been created by me on purpose. I tried opening a couple of them, and got messages about various updates Firefox wanted to perform, but none of the opening screens had my information loaded. I've just lost a half hour of my life down this rathole this morning, and I still haven't gotten around to completing the search which was the reason I opened Firefox this morning in the first place. Imma have to go back and use Safari I guess, since Safari isn't suffering from "Susan Amnesia"

Dear All, my Firefox is broken. It starts and shows a blank tab, but I cannot open any site, not even about:config or the options pane. Typing anything in the address bar or the search bar and pressing Return does nothing.

The only things I can do is opening new tabs (which will remain blank), and clicking on menu items in the main menu. None of the items that would open any dialog works, though.

So far I have tried:

  • Starting Firefox in safe mode
  • Creating and using a new profile (firefox.exe /p)
  • Uninstall FF and re-installing the latest version
  • Uninstalling FF and installing a previous version (downgrade), using a new profile
  • Deleting all mozilla and firefox entries in the registry in an uninstall / reinstall cycle

Now I am out of ideas. Any help is welcome. Thanks!

Flash plugin is not the problem- it was installed during this whole mess.
