Firefox 140 - Now have issues with background colors in Sideview bookmarks

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

I am currently using Windows 11 and Firefox 145.0.2 on my desktop computer. Firefox is set as my default browser. Since the latest Firefox upgrade, the "Downsize/Minimize/Exit" toolbar does not appear upon opening and the only way I can close the program is to go to File<Exit, but I still have no way to downsize to share my screen with other applications. I sometimes have to open and close the program a couple of times before the Minimize toolbar appears. I already tried Firefox "Refresh" but the issue is still happening. </p>

How can I get all Firefox settings as a simple table? I am sure that is how they are kept by the program, somewhere outside the Firefox UI. Are they kept in the System Registry? It would sure make troubleshooting & continuity easier when moving to new devices/CPUs.

Clicking those options fixes nothing! How do I go back to the previous version, please?

I noticed recently, that you cannot copy and paste with the right click mouse buttons and seems to want me to use the Cntrl C and Cntrl V. Is there some way to re enable that on the mouse? It works in every other application except firefox, and I would prefer to use the mouse, as I am the most comfortable with that.

I installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.
