Hello, I decided to post here instead of seeking help/assistance on the Firefox reddit.

About a week or so ago I was using Firefox fine, no issue and out of the blue it just stops wanting to launch, or if it does launch it's stuck on a dark window, I was using the dark theme, that looks like it has a loading bar on the page tabs and in the url bar. It just hangs here indefinitely, the only way that I can close down Firefox is by opening up ProcessExplorer64 and killing it that way; it does not respond to task manager at all.

What I've done:

Uninstalled / Reinstalled firefox; Updated my drivers; Turned my computer on and off again; Completely turned off, unplugged and power cycled my computer; Made it a firewall exception; Ensured my internet is connected and my computer has it (I use Discord and Chrome, in fact I have to post this in Chrome.)

What I do not have:

Anti-Virus; My computer is clean, if I could I would eat off the data and suffer no infection from it. Norton/Comodo/Avast; There is no anti-virus. There is no adware, malware, trojans, viruses or spyware on my machine. Going to the same three websites since 1997, no malicious programs are downloaded.

What I have tried related to Firefox:

Running in Safe Mode: Can't access safemode, browser does not launch far enough to have the menu interactable. Trying to launch the profile manager yields nothing. Uninstalling and Reinstalling Firefox yields no result. The only error that I have gotten is a XPRCOM error or something and the solutions for that have not worked for me as I do not have multiple installations of Firefox on my machine.

I would attach a screenshot of how Firefox looks, but I am unable to as of this post it has devolved to launching as a background process and crashing immediately.

Help?

App is broken; something is wrong. I'd like to use a Browser that is not Chrome.

Chosen solution

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.


Download Firefox For All languages And Systems {web link}

Firefox ESR; Extended Support Release {web link}

Beta, Developer, Nightly versions https://www.mozilla.org/en-US/firefox/channel/desktop/

Install Older Version Of Firefox {web link}


Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

  1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
  2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

I have no access to this as Firefox is unable to load at all.

It's black/grey and the moment I click on or interact with it it crashes.

Is there a folder somewhere the crashes log to?

Attached is a screenshot of how far Firefox loads when I launch it.

Yes, but in this situation I'm not sure if they're being submitted to our server. You can use the following steps to find out:

  1. On the keyboard, press [Windows] Windows key + [R]. This should bring up a Run window that contains a text field.
  2. In that text field, type %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID with bp- into the reply window on the forums.

Do you recall that another program has been uninstalled recently?

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

Install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads

You may not need the latter (32-bit version) if you use 64-bit Firefox. You may have to reboot the computer.

There's only two in the submitted folder.

As for the Visual Studio update, I have that update downloaded already. Another program I used three weeks ago needed that installed to function properly.

Okay, I spent today running scanning software, including the ones listed and all that was found was tracking cookies and a pup; there's no malware on my machine.

sfc did find one file wrong... I misread the text block.

Update:

After completing all the steps from running malware scanners to doing dism/scannow a few things happened;

1.) Tracking adware cookies were found and one pup was found. 2.) sfc /scannow found one corrupted file and replaced it; dism had no issue. 3.) After doing a hard reboot my computer has loaded up faster, but Firefox still does not load.

I've been launching firefox for a bit now, hoping it pops up with the crash report window so I can submit another crash report. Alas, no luck.

Thank you for the assistance.

This was a mix of two things, invalid installation for Firefox; in fact I didn't notice when I ran the installer I was just refreshing my installation. Also unbeknownst to me at the time the drive I was installing to was starting to show signs of crashing/corruption, so after uninstalling and reinstalling to a new drive all problems have been alleviated.

I've installed the enterprise version of Firefox, it sounded more secure than standard.

Thank you both for assistance. This was a weird, strange trip through user error and hardware degradation.
