FF ver. 91 update not loading GMail (no themes, invisible functions/buttons/etc.)

After installing FF ver. 91 for Mac OS (desktop) GMail will no longer load its themes, and only appears as a black and white simple HTML version. Many of the page functions are there, but invisible, and can only be found by hovering the cursor over the general area where these active and regularly used GMail features are on the page. Many page elements also have wire frames around them. Even the GMail log in portal screen is not displaying correctly. The Google Workspace logo also fails to fully animate when navigating to the login page.

Reverting to older versions, FF 89 and 90 proves that the problem is with FF 91. The issue does not affect Safari or Chrome in my experience. Totally clearing all cache, cookies, sync'ed profiles and user accounts in this FF product does not fix this issue with FF 91.

This appears to be an interface bug that needs to be sorted. Can you please help?

Recent release notes say that Firefox automatically enables High Contrast Mode when "Increase Contrast" is checked on MacOS. It can be turned off in FF settings under General -> the Colors... button -> Override the colors specified by the page with your selections above -> Never.

Many thanks for providing this solution!

Prior to this solution, even the Preferences interface was difficult to navigate as dialog boxes layers were transparent and interlaced with page text below them.

I am using Firefox 93.0 on a MacBook using macOS Big Sur 11.6. When logged into my Gmail email, my company logo used to display in the upper right-hand corner. Lately, it has just a gray box with a squiggle line. It shows up just fine in Chrome. I have to go into the settings under Privacy & Security to clear out the cached web content. Then I have to reload the page ("Command + Shift + R" (MAC) ). This works for awhile but I am having to do this many times a day now.
