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 always use Firefox, but lately it's been acting funky; that is, about every 5-10 seconds it pauses (the cursor spins, so I cannot use it), and even when scrolling it does that. Driving me insane. So I thought I would try Internet Explorer, and it was fine. So, I went to my downloads, and I noticed two Firefox's. When I clicked on them, one was Firefox, the other Firefox 2. I have no idea why, but I must have been upgraded, or downloaded new version, who knows. Anyway, Firefox was the culprit, and Firefox2 is my old, regular friend. So, if you are having this problem, that might answer it for you.

Hi all. Seems like after updates, my computer slows down. It has become so recognizable, I know when the registry errors appear, as my computer performance falls off. I must use Reginout Registry cleaner, and CC Cleaner to restore performance. Along with any FireFox updates, my bookmarks have all been deleted many times over. I no longer attempt to re-install, as they continually get deleted, and so simple fix is available to me that I can understand. Thank you.

Hello.

A couple of days ago, I was having problems with Firefox crashing when I opened it--no window would open at all. Prior to that I was having problems for a few hours with Firefox being extremely slow and getting stuck. This is with a MacBook Air with Catalina installed.

I did what I thought was clean reinstall and restored by profile from a backup. I had to try a couple of different times to get it to work. I did wind up losing my previous session.

Things seem to be working fine, but in the Firefox Windows menu it shows a window I can't access, close, etc. The tab open in the window has the title "Firefox protects your privacy automatically." I tried the "Show All Windows" command and only the other window "Google" can be seen. See the two screenshots.

I tried restarting Firefox in Safe Mode, restarting my computer, etc. and that has not helped.

During the reinstallation, I think I remember briefly seeing a different window with a tab from Firefox with this name, but I might be incorrect.

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.

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.
