Firefox just updated to version 89.0. I find the enlarged bookmarks names in the bookmarks tab, the new coloration, and the new floating tabs to be a hindrance. To elaborate, I have a form of red-green colorblindness and find the floating tabs and lighter coloration make it harder for me to use the interface, enough so that I am considering switching browsers. Is there a way to revert these visual elements to the older version?

Thank you.
