I am not able to load any websites with Firefox on my PC despite having an internet connection. I went on Reddit and found other people complaining of the exact same issue, so it appears to be a problem with firefox: https://www.reddit.com/r/firefox/comments/s2u7eg/is_firefox_down/

My phone’s firefox browser works fine.

What can cause a browser to fail this way?

    Stickied your post for visibility.
    Edit: It’s been fixed already.

    Firefox has witnessed outages and we are sorry for that. We believe it’s fixed and a restart of Firefox should restore normal behaviour. We will provide more information shortly.

    Also, disabling telemetry doesn’t fix this issue anymore, the telemetry servers weren’t the root cause and have been adjusted already.

    Our current suspicion is that Google Cloud Load Balancer (or a similar CloudFlare service) that fronts one of our own servers got an update that triggers an existing HTTP3 bug. Telemetry was first implicated because it’s one of the first services a normal Firefox configuration will connect first, but presumably the bug will trigger with any other connection to such a server. Our current plan is to disable HTTP3 to mitigate until we can locate the exact bug in the networking stack.
