Dear mozilla community,

I cannot get firefox to start, and I need help to troubleshoot this. What I already did:

  • remove and reinstall (apt)
  • rename ~/.mozilla to trigger recreation
  • start using the command line
  • start in safe mode

The only symptoms are <defunct> processes (see screenshot).

I need more information to find out what went wrong. Where can I find this?


Details

  • apt
  • firefox_78.0+build2-0ubuntu0.16.04.1~mt1_amd64.deb
  • Linux Mint 18.3 Sylvia

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.

Alright, I use Firefox like normal, but sometime today it stopped working, I get "Your Firefox profile cannot be loaded. It may be missing or inaccessible" error, I looked it up using safari, followed every possible interpretation of the instructions to no avail, I deleted the profiles folder and file, in both cache, and application support, on both my user folder and global HDD folder, no fix whatsoever, I don't know why this isn't working (yes I checked the hidden files, I searched my entire HDD and found no results for anything remotely named "Profile"/"Profiles" and I don't know what else to say.

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.

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

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.

How it happened: 1. I installed Anaconda(python3.7) and Visual Studio 2015 (to get the required C++ for TensorFlow) 2. Decided to uninstall Anaconda and Visual Studio 2015 and restarted which is when firefox gave the error vcruntime140_1. dll was not found. 3. I downloaded and installed vc_redist.x64 and restarted 4. Firefox does not give an error anymore but no websites appear (just bank screen). I can see the firefox dropdown tab for options, but clicking options does nothing


What I've tried: 1. Uninstalled firefox using an uninstaller that removes residual files 2. Re-installing firefox 3. Running firefox in safemode and clicking 'restore' as well as trying it in safemode


Chrome is working with no issues, but I prefer firefox.

73.0.1 (32-bit)

This HP Elitebook 840 G3 running Windows 10 v 1903 64-bit. Have to be careful re-installing as FF wants to make my extensions in GERMAN! Are OK now (see attachment). Have test-removed AdGuard, NO difference, so added it back.

NOTE: screenshot is long out-of-date: AdNauseum removed long before this issue started

Hi. I use Firefox from many years. Today I was trying to inspect a my web page which looks strange in my Firefox for Android but I just can't. In my desktop I have Firefox 73.0.1 and in my Android phone I have Firefox 68.5.0. If I try to connect I get a message which tells to update Firefox from 68.5 to 71.0 (minimum supported version) but I can't find this version anywhere. I have installed Firefox Nightly for Developer in my phone but now the problem is that the version is too recent... What should I do?

The installation progress bar stops at about 75% and then a message appears saying, ‘Hmm. For some reason, we could not install Firefox. Choose OK to start again’. BUT it won’t start again and if I try to download from your website, the whole process happens again. This is very frustrating as many of the websites I use, are linked to Firefox. Please advise.

Hi all

For security reasons, all new FF distributions are tested. When checking the distribution kit version 68.5.0esr (exe for x86 and x64) - the antivirus software "VirusTotal" detected Trojan.Inject.bcbj. FortiSandbox also scolded the distribution on x86 - saying that it deleted the file "% programfiles (x86)% \ google \ update \ 1.3.33.17 \ googlecrachhandler.exe" - its installation is undesirable in the ESR version.

Hi,

I have spent hours dealing with this issue. I hope someone is able to assist me.

I ran into some issues with Firefox so I went to reinstall it but I am unable to open it. I noticed even after uninstalling it it was still showing up when I do control/alt/del. I have tried to close it but it won't close. I have tried almost every option I can find online to force close it.

My issue is when trying to open my new version of Firefox I am told I have a version running and must close it.

I have tried to delete it I don't know how many times.

I am running Windows 10.

Is someone able to assist me? It would greatly be appreciated.

I hope someone can help me as this is getting very frustrating.

Thank you .

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.
