Firefox not opening
Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

What security software besides MS Defender are you running? What version of Firefox? If Windows Pro version, try testing in Windows Sandbox (VM) to see if you have the same issue. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/ Could also test with windows in Safe mode with networking
Hello, I have version 140.0.2 of firefox and no antivirus other than windows defender currently installed (looking to change that soon but wanted to fix this first). I am not on w11 pro either, so cannot test in VM. How do i test in safe mode with networking? Many thanks!
