An outage currently seems to affect all Firefox users. Unable to access any website.
The problem seems to be related to HTTP3 support in the browser. It’s not yet known exactly what Mozilla has done wrong, but if you’re currently having the problem, here’s a way to fix it.
Edit2 : The problem seems to have been solved by Mozilla.
Edit1 : A ticket has just been created on Bugzilla . It seems to be related to data collection. To deactivate it:
Type in the URL bar:
about:preferences
or go to preferences -> Privacy and security and disable data collection:
Otherwise, another workaround:
Type in URL bar
about:config
Click the blue warning button, then find the key
network.http.http3.enabled
Set it to ” False ” by double clicking on it.
Then restart your browser.
Good luck. I’ll edit this article when we can all re-enable HTTP3.
