Firefox stopped working
Hello My Firefox browser stopped working suddenly. I used it this morning (11/12/21) without issue but when I tried it around 6PM CST US I got PR_CONNECT_RESET_ERROR on everything I tried to load. There was no updates that I am aware of and I tried all of the solutions provided on sites I visited up to and including disabling anti-virus with no success. For now I've uninstalled the product until a solution has been found. Thank you to anyone who may be able to assist in this problem. All other browsers I've tried work as expected.
(System Windows 11, Anti-virus Kaspersky Total security)

I found the issue. It was Kaspersky. As per a post on the Kaspersky forum, I completely uninstalled Kaspersky without saving any settings as https://community.kaspersky.com/kaspe.../firefox-94-0-1-unable-to-connect-to-any-website-showing-pr-connect-reset-error-21416 after a complete reinstall Firefox is now working as it should. Thank to all for the help.

Don't disable Kaspersky, turn it off and try again. Also, you do not have the current version of Firefox. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Web search; https://www.bing.com/search?q=PR_CONNECT_RESET_ERROR This simply means, that the peer or some middlebox in between (firewall) is terminating the connection.
There is security software like Avast, Kaspersky, BitDefender and ESET that
intercept secure connection certificates and send their own.

I have tried everything listed here still not working I even turned off Kaspersky completely still not working. Thank you for the help.
Start Firefox using Troubleshoot(Safe) Mode {web link}
A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

As a test, disable your protection programs.
