 Yes. It's not *Tor*-related but related to the above mentioned browser
 settings which are still active even if you configure a different proxy or
 none at all. We need #14952 sorted out first, to solve this problem which
 is supposed to happen soon.

 It indeed **does help** - facebook loads instantly.

 > Maybe bugs like these can be simulated with a `firejail
 --bandwidth=torbrowser set eth0 5 6` or worse, I don't know, but it seems
 like this is due to static.xx.fbcdn.net being overloaded by exits, and it
 took time to load up and something weird happened. If I recall trac.tp.o
 had also some overloading issues at the time, maybe that's why gk was
 experiencing a similar bug at the time.

 Good idea, but I think it's something different here. OP: does it help if
 you flip `network.http.spdy.enabled` and `network.http.spdy.enabled.http2`
 to `true` (just for testing purposes)?

Comment (by cypherpunks):

 I wonder whether this is a duplicate of/related to #21924, gk says there:

 > **This change e.g. if I go to Trac in a new tab. Suddenly the icon on
 the former tab stops spinning and all is fine.** This happens at least
 with a 64bit Linux.
 >
 > (Sorry for the vague bug report :) )

 Which seems to be the same case here (except the bug report is more
 precise :) ).

 In the meantime you can use the Facebook onion service
 `https://facebookcorewwwi.onion/` which doesn't have this issue
 (hopefully).

Comment:

 Hm, I wonder what's up here. Do you have some antivirus/firewall tool that
 could be interfering? If so, could you uninstall it for a test (disabling
 is often not enough) and see if that fixes your issue?

 Problem:
 After opening the Tor Browser and typing in facebook.com, page loading
 hangs, status bar showing "Waiting for static.xx.fbcdn.net"

 HTTP GET requests for small images from static.xx.fbcdn.net stall in the
 "Blocked" state for minutes - viewed in Developer tools / Network /
 request / Timing (see attached screenshot Step2.png).

 When a different website is opened in a new tab, HTTP requests continue
 loading successfully - seems to be some livelock within the browser.

 This is **not a network issue**, connectivity in the browser works fine,
 also verifed without a SOCKS proxy (direct connection without Tor).

 Reproducibility: nearly 100%

 Environment:
 - Windows 10 Pro, 64bit
 - Tor Browser 7.5.3 for Windows, english
 - Tor Browser 8.0a5 for Windows, english
