After the automatic upgrade to version 91.0, a variety of websites such as GMail, YouTube, MarketWatch are being displayed in a very rudimentary manner (see screen shots). I've refreshed, as well as reinstalled my Firefox instance and there was no change to the websites' display. Viewing the websites on Safari or Chrome yields correctly displayed sites.

Hi Dave, I might be duplicating what Shashank Shekhar is typing, but just in case:

Firefox 91 now automatically enables High Contrast Mode when "Increase Contrast" is checked on MacOS. (release notes).

Is it possible you have that setting?

If so, please try one or both of these two options:

(1) Turn off the system-level setting. This appears to be the most effective workaround.

(2) Disable High Contrast mode in Firefox. See: Disable high contrast mode in Firefox.

For both changes, you might need to Quit Firefox and start it up again to see the normal display.

Any difference?
