User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0
Steps to reproduce:
My Windows 10 PC has downloaded security update : Version: 1.355.1825.0
Actual results:
No Internet, Firefox was waiting for ever, while other browser where working fine
Expected results:
I had to manually unlock Firefox in Windows 10 Firewall.
This is not a FireFox bug, but it is the only way to inform you with this issue.
It might impact a lot of people (Windows 10, using default Firewall)

Is it still broken today, if you re-enable the firewall? Firefox was broken for everyone yesterday, at the time you posted your bug.
Hi Francesco, no I fixed it from Windows 10 Firewall. Strange because I have not disabled http3 nor data collection
I made two experiments :
- upgrade from 95.02 to 96 : Firefox still working fine
- removed Firefox exception from firewall : it is still working fine. I noticed that I had two exception, one with FireFox only, the second on with full path of firefox. I removed one of them and disabled the other.
I have used this article, even if it is outdated : https://support.mozilla.org/en-US/kb/configure-windows-firewall-allow-firefox-access
