(Of course, that may or may not be the case with the page(s) giving you problems.)
</p><p>I assume you've done the standard troubleshooting for the problem site(s), e.g., clearing cache and site-specific cookies, trying Firefox's Safe Mode?

Is that helpful at all in resolving this?

</p><p>When i said im not sure that bug started with 20.0.1 i meant it was fine in 20.0 but then again i think i installed new fonts between both releases so that might have caused it rather than the update.
</p><p>edit: is it normal that about:telemetry says "no data collected" at "browser freezes" (not sure if thats the correct word, my firefox is in german) even after experiencing several freezes already?

</p><p>A possibly similar bug was filed for Firefox 19: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=853626" rel="nofollow">853626 – Firefox hangs when accessing battlelog.battlefield.com due to slow Font Loading</a>. However, that doesn't seem to be going anywhere due to lack of data, and the reporter said it only affects the site if it is the first site loaded during a session, which I think is different than your issue.

</p><p>Perhaps before downloading, however, Firefox has to search for a font on the system to use temporarily, or compares metrics? With so many installed fonts, I suspect you have surfaced something very inefficient that no one noticed before. There may be some profiling tools to test that theory, but it's well beyond my expertise.
</p>Thank you jscher2000, that fixed it and i can also guess why now that you brought fonts into play.

</p><p>I got around 12.000 Fonts in my Windows Folder (yes i know that's alot but i typeset alot of stuff), does Firefox look through them or cache the downloadable fonts in there or something?
</p><p>Is there a way to keep both my current Windows fonts and see downloadable fonts by websites (like disabling that firefox does whatever it does)?

</p><p>I tried using the web console but other than the processing times it doesn't tell me much of what is happening. I attached a image, in there you can see how it hangs up. The file takes 185 MS to load yet the browser doesn't get the next file until a good 1 minute and 15 seconds after (thats the time it hangs). Loading the File alone in a single tab takes around 44 MS.
