Genuinely, I cannot reproduce the issue. I ensured that both DoH (set to Cloudflare) and H3 are enabled but didn't hit the snag, so either Cloudflare has a buggy deployment or the hunch ( https://bugzilla.mozilla.org/show_bug.cgi?id=1749908#c6 ) that it's telemetry activating H3. Update: using Google's ( the horror ) DoH, and I didn't notice problems. Might just be CF having a bad H3 deployment, but I want to know wh…

I think it has been fixed, I didn't do any fixing on my own and it just worked after 20-30 minutes again

I had the issue earlier today, then after a restart it went away. Not 3 minutes ago it started happening again. A restart then didn't work, but disabling http3 got me up and running.

Earlier quoted context omitted.

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.

Which wasn't present in previous versions. So this is still a consequence of updates. But now, to make it extra hard to troubleshoot we put in timebombs in your automatic updates that will go off some fine Thursday morning without any warning or indication that something has just changed. Idiots.

Looks like HTTP/3 has been in Firefox for around a year

Disabling DoH and properly closing Firefox most certainly works (for me). However, if you had enabled DoH then you probably do not want to turn it off, in which case disabling HTTP/3 as mentioned is the only proper solution.

> However, if you had enabled DoH then you probably do not want to turn it off Or you simply didn't know that Firefox made it the default a while ago. I had it intentionally disabled on one machine but forgot that it's enabled on others, which made troubleshooting even more "interesting"... Why do things work on one machine but not the other?

Oh, interesting! I did not know it is a default now. I can imagine why they would enable it by default, but when Cloudflare (which I assume is the default DoH provider) has a problem at some point everyone is doomed.

Really wish they also could make it so the data collection part is opt-in instead of opt-out (which at this point in time appears to be the actual cause of this problem).

EDIT: FIX worked temporarily.. had to go the network.http.http3.enabled route, sorry folks I literally just fixed this problem by installing that microsoft visual redistributable https://support.mozilla.org/en-US/questions/1326304 It just started happening to me after i updated firefox.. I installe that VC runtime, restarded, and now it works.. didn't have to disable anything in the browser.. this has been happening…

I can confirm this on Windows. Just installed the latest VC++ redistributable and now FF works even with network.http.http3.enabled set to true.

The problem came back :( had to disable network.http.http3.enabled

I know it's a rant for which I may get downvoted, but I've grown really tired with Firefox.

It's only my laziness (having to recreate all the setup, find equivalent extensions etc.) that keeps me from switching to another browser.

Crashing tabs, losing pinned tabs, having to restart the browser when I switch to another wi-fi (eg. return home from the office), or otherwise all I'm getting is SEC_ERROR_BAD_SIGNATURE errors (not a problem for any other browser somehow!)... or even those silly dialogs that inform me "Firefox is already running, just not responding" when I close and try to reopen it, because apparently it lingers in memory, sometimes for like half a minute, when I'm only trying to get stuff done. These little slaps in the face really add up over time.
