Almost every site is broken in Firefox 77

I just upgraded to Firefox 77, x64, Windows 10 2004.

Firefox 76 already broke LockWise - https://support.mozilla.org/en-US/questions/1287008

Now Firefox 77 breaks 99% of all websites. (See attached screenshot.) www.example.com www.google.com www.wikipedia.org etc

Somehow, support.mozilla.org works, UNTIL I try to log in.

I've tried incognito mode, safe mode, etc. When I change charset of the page, the text displays differently, but it's still a useless mishmash.

--- BUT --- when I open developer tools, click the HTML request and click the Response tab, the HTML renders correctly there.

Since updating Firefox to 78.01 (I haven't updated recently so have skipped a few versions) a basic HTML5 website no longer works, the page based on a Uniflip brouchre doesn't load correctly http://www.tmlcnc.com I have tried safe mode, disabling addons, updating addons etc, but no difference at all.

Website works fine in IE 11.09600

Not had this sort of problem before, websites normally work in FireFox but not IE !

Any ideas ?

When I try to load the sleepiq web site I get this: https://sleepiq.sleepnumber.com/#/ and a blue screen. When I load the same website from Chrome I get this: https://sleepiq.sleepnumber.com/#/dashboard/sleep, and the page loads. Safari is the same as Chrome, I get the information I'm looking for. As Firefox is my default browser I'd like to be able to fix this problem.

The Doki Doki Live site won't load any live stream. I've tried Chrome, the old Edge, the new Edge and Brave. They all load everything with no problem, but that particular site on Firefox won't load up the live broadcasts, but will load a video there. I've refreshed the browser, uninstalled and reinstalled it and nothing works. I am using the latest version of 78.0.2

Hi, Since I've updated to Firefox 79 beta I can't access my university campus website. It worked until Firefox 78 and it works with latest Chrome and Edge, but not in Firefox 79 beta and nightly.

The error is: "Website will not allow Firefox to display the page if another site has embedded it": https://support.mozilla.org/ca/kb/xframe-neterror-page?as=u&utm_source=inproduct

Is it a bug or a "feature"? UOC is one of the biggest online university of Spain, it will be a "disaster" if students can't access it with Firefox.

I can explain you how to reproduce it because it's the private area and you need student credentials to enter, but the login website is: http://cv.uoc.edu

In the console I can see some errors like this: Cookie “example” will be soon treated as cross-site cookie against “http://cv.uoc.edu/rb/inici/plin/fonts/icons.woff?cc152853f8bb07259fb3eb89b6fbfee7” because the scheme does not match.
