Hi, my Machine updated from 140.0.4 to 141.0 since then I cannot start up Firefox anymore. On startup after a short pause the Crash Reporter shows up - interestingly the Crash Reporter may enter a endless loop and opens up multiple times. While that the CPU load is at 100%. I tried
as well, for those I get the same behavior. I tried downgrading to 140.0.4 - after that a profile dialog shows up which tells me that a new profile needs to be created due to a downgrade. After that Firefox comes up fine with the new vanilla profile. IF Firefox updates to 141.0 (in background) the next startup with the vanilla profile doesn't work gain. Which brings me back to the initial problem.
Workaround for now:
My environment:

Firefox has been working fine, but today when I clicked to start, I received an error message. "The file or directory is corrupted or unreadable." When trying to uninstall Firefox, Windows cannot find the uninstall helper. When I try to download a new version, I receive an error message: "Couldn't download - virus scan failed." Windows Security reports are all good. A scan found no viruses. Firefox will not open at all.

When opening Firefox version 147 it asked if I wanted to install updates and after answering affirmative, then it gave "Error: Platform version '147.03' is not compatible with minversion >=147.02 maxversion <=147.02. Maybe try to reinstall Firefox?" The browser will not open. What is the workaround??
Is there any update on this issue. Do I just need to download a different browser and stop using Firefox?
Thank you.

Firefox has begun to instantly crash after opening. This occurs constantly, even though fresh installs, even if I run as administrator. It is the only application doing this, which is beyond weird. It seems to have begun happening after I opened a notepad file. Which seems ridiculous to me but that's when it initially crashed. If more information is required, please let me know, but I cannot even access say, crash logs.

Dell installed a command update and immediately afterwards, Firefox would no longer open, either from the taskbar icon or from settings/apps. I just get a couple of seconds of the blue cycle icon and then nothing, no error message, just nothing. I did download/install repeatedly but I don't get beyond the download screen - as soon as it's 100% downloaded, that's it, no welcome window, nothing. Thanks

When I first open Firefox from the icon in my taskbar the opening window says the following:
'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'
However this is only the first window, after that I can open a new tab in the same window without any problems.

Here is what the message says: "Firefox is trying to install a new helper tool. Enter your password to allow this" I tried to install but Firefox won't open. Firefox icon just bounces around, I have to force quit to stop it. I DO NOT WANT THIS TOOL BUT I WANT TO USE FIREFOX. By the way this is sent from my other user, as the problem is on my admin. user and I can't open Firefox to do anything!
I can't start my Firefox
