Hi, The attached image explains the problem in 3 steps. 1. I try to add a bookmark, a pop-up window appears. OK. 2. I get a menu with some recent bookmark folders, but I want a different one, so I press "Choose folder". OK. 3. Now I need to browse among numerous folders in my bookmarks, it worked fine before, but I cannot do it anymore because the folder names are not visible! As if they are written with a white font on a white background. I can scroll, choose (blindly) some folder, which is marked by the faint rectangle visible on the image. And the bookmark will be saved to that folder indeed. But scrolling blindly through my hundred folders is obviously not practical. The problem appeared 1-2 weeks ago, probably after a FF update. Now I updated FF to the latest version 97.0.1, it doesn't help. A couple of months ago I did some changes in FF config in particular to make bookmarks appear more dense: newer FF versions introduced huge vertical space between bookmarks. I can't remember what exactly I did (followed some recipe on internet), but it didn't introduce any problems. The problems appeared 1-2 weeks ago. System: Windows 10.
