Not much else to say. Firefox upgraded to v. 91.0.1 when I restarted my iMac this morning. Most of the colors, banners, any graphic elements have disappeared from all websites I access. If there isn't a fix for this (and I can't imagine it was intentional to remove most colors and have no way to restore them), how can I go back to the previous version? Most websites now have just white backgrounds and look nothing like they are supposed to. Also in Google mail and calendars, all label colors have disappeared so everything is just black and white. Please help with this. Thanks.

First image is how Ancestry.com looks in the new Firefox version. Second is on Safari and looks the way it's supposed to.

This could be a problem with High Contrast Mode on Mac.

See "New" in the release notes.

Firefox now automatically enables High Contrast Mode when "Increase Contrast" is checked on MacOS in the Accessibility settings.

Make sure you allow pages to choose their own colors.
