Hi,
I don't have the technical knowledge to confirm this issue but I'll add product and component so the team can make some research on it. Hopefully, someone with a more deep understanding of this matter can help. Feel free to route this ticket to the corresponding team.

Regards,
Jerónimo.

I don't think DOM:Events is the right place.
Hi Gijs, can you suggest to which Firefox component we should move this bug so the right folks can take a look? Thanks!

Are there any errors in the browser console (open with ctrl-shift-j - Note: this is not the same as the regular developer console) when opening the about firefox window?

Note that I can use Firefox 78.0.1 (64-bit) on the same OS platform to browse any site, with multiple tabs opened.

With Firefox Developer, there appears to be a process that's taking 25% CPU or more (on a 4-core CPU) that appears to be blocking any HTTP GET/POST request.

Thanks for the info.

That does sound like it would also be causing the update problem (because checking for updates requires making a GET request). Does starting your Dev Edition in safe mode help with either updates or with other requests?

Comment 9

[Chua Chee Wee]

I started in safe mode, and Dev Edition still can't retrieve any sites.
I've got a Firefox account, so my settings in Firefox 78.0.1 (64-bit) are sync'd with my Dev Edition's.
At the moment, Firefox 78 works, but Dev and Nightly can't retrieve sites.

Thanks for checking.

That puts this problem a little over my head, I'm afraid. I think we've established that whatever is going on is bigger than updates not working though, so I'm moving the bug back out of this component and changing the title.

Comment 11

[Mike Conley (:mconley) (:⚙️)]

Sounds to me like this might be a networking issue, so moving over to that component.

Do you have network.http.http3.enabled set o true? (http3 is experimental and still not ready. the http3 version in 79 does not wok well)

If answer is no can you make a http log?

It's enabled in the about:support data (see attachment), so this is probably it...

Ah sorry, I missed the attachment somehow.

Comment 15

[Chua Chee Wee]

Yes, I have http3 enabled. I'm gonna try turning it off on Dev and Nightly, and see if that works.
Will this cause 78.0.2 (64-bit)'s http3 setting to be disabled as well?

How does the sync work if there are conflicting settings between different editions of Firefox?

Comment 16

[Chua Chee Wee]

Ok, it now works on 79.0b6.
I'm gonna close this.
