Re: Ask HN: Firefox connection problems after enabling DoH?

i just got this. From one moment to the next it seemed my internet or DNS was down. Chrome worked fine however, no issues at all while firefox couldn't even load https://1.1.1.1

I rebooted my PC and it seems fixed. Weird how this bug suddenly pops up. I don't even use DOH. I had to kill the process on Linux to even restart Firefox, but I needed a full reboot to get connections again.

I'm typing this from my rarely-used Chrome install. Firefox just broke for me, and killing all the processes and / or restarting isn't helping. Edit: I am on Firefox 91.4.1esr, so clearly it isn't just the latest versions that are affected.

Heck, I'm running 88.0.1 and still get this. Probably some unintended timebomb bug in the HTTP3 code...

What worked for me was disabling HTTP3 support with the 'network.http.http3.enabled' key in about:config and then restarting Firefox. Seems like it's stuck in the 'SocketThread', repeatedly doing this: 2022-01-13 08:20:53.075936 UTC - [Parent 4106991: Socket Thread]: V/nsHttp Http3Stream::OnReadSegment count=333 state=4 [this=7f6e295623a0]

Thank you very much! Saved me a lot of time.

I will have your babies, and that’s coming from a straight male.

It is time for Mozilla to stop messing around. They are losing user trust extremely fast. A silent FireFox update that cripples the browser? No active update was done since yesterday and this morning: a broken browser. Please stop non-browser development and let me pay a monthly fee for a decent browser! I don’t want a VPN service, bookmark readers or other crap. I want Mozilla to defend the open web and create an op…

It was not an update, started happening to me on arch linux, where Firefox does not automatically update. Seems like some kind of timed enabling of https3 support.

It seems like it has nothing to do with the version, so it's not an update from Mozilla's end. Still bad though.

I really hope the auto-update component doesn't have the same issue, otherwise Firefox is essentially dead on millions of computers owned by non-techies.

I fear not. With http3 enabled, the auto-updater never returns a result. It keeps saying "checking...". Looks like the auto-updater itself will work only when http3 is disabled through about:config which non-technical people may not be able to do.

However I do recall Mozilla having another backdoor channel which they used sometime ago to push an emergency update. I hope that works.

Oh wow, thank you so much for this. I've been trying to troubleshoot this for hours but because my browser didn't work I never thought of checking HN to see if other people had this as well.

Another score for automatic updates I guess.

Manual install on aging Ubuntu refused to load pages and pegged CPU.

Manually reverted, and launching my older version (92!) demanded I either create a new profile or quit.

This would have been a disaster except I tried it out on a spare profile in the first place, so I recommend this to anyone making a similar experiment.

I haven't set DOH (!) that I can remember.

Running through the initial ff setup a couple of times is a sad reminder of the progressive influx of crapware into my sill favourite browser.
