Webpage display problem with v91 for Mac

I've been using Firefox for years but I am stuck with this problem. Firefox just updated to version 91.0 (64-bit) and now webpages are not being rendered correctly as per the attached screenshot. It seems to be a selective CSS issue and it is across all pages.

I have tried restarting the computer, clearing the cache, and changing the theme. This is happening on two different Macs both running macOS v 11.4.

The first image shows the page in Firefox, and the second in Safari (and how it used to look in Firefox before version 91).

Does anyone have any idea why this is happening?

I just realised that this is because Firefox is automatically using high contrast mode when "Increase contrast" is set in the macOS system preferences, and that this can be turned off in FF preferences under General -> Colors -> Override the colors specified by the page with your selections above -> Never

I had to stop using FF yesterday because some webpages were rendered in a strange way and unusable. This trick solved the problem for me, thank you very much!

This is not the only problem.

I have other sites where the CSS is just not recognised. I have now stuck to v90

First I do want the high contrast so turning Firefoxs option off is not a usable option

I use Tree tab Style for tabs and Stylus for altering CSS. Even with the firefox flag not set the tabs are all white and the CSS override does not work.

Can we please revert the code to a working version
