Diễn đàn hỗ trợ Firefox

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

firefox doesnt start and gives me this error If i uninstall the have a fresh, install, everything will work normally until i restart my pc

In my org - ever since the release of Firefox 146 - each time an update is rolled out on a WIndows 11 endpoint - Firefox is no longer able to launch.

This is resolved by uninstalling and reinstalling the client. We've had no issues with the ESR release in my testing.

What changed? Anyone else experiencing this?

I had our security team take a look at the antivirus - they've confirmed we aren't blocking Firefox and they did not see any block reports.

No relevant policy changes have gone through around the time of the incident. Initially I suspected users were installing Firefox ESR from the Company Portal alongside the standard release - but confirmed this is not the case. Also ruled out browser extensions - error persisted across a config without any extensions.

Please let me know if there is troubleshooting info I can collect. I included info from my own browser, but I reinstalled on the 27th and it has been working since. However, it has broke specifically on the days new releases have come out.

Thank you for any suggestions!

i downloaded the installer on windows 11 and it would not go up. it just stayed at 0%. and i wet t the fallback download and that worked but the download downloaded Firefox but yet it opened for 2 seconds and closed. and refused to open from that point! what do I do?
