I recently switched from FF 116 to ESR. (I wasn't allowing updates until I had video difficulties) I just wanted my browser to work and be simple; I hate changes, especially some of the things Mozilla bombards us with in updates. (I wish I could choose what I want and not be forced to accept all of it.) To solve my video problems, I had done a refresh with extreme trepidation and that didn't help, so I decided to be on a new version of FF/ ESR because I was nervous about the latest FF. I only understand tweaking in config and adding extensions. I don't know anything about CSS, and I don't want to. :) I did change the density setting in config and chose that via 'customize toolbar.' The density is not compact enough for me. Before in regular FF, I had a tight look to my bookmarks as they dropped down. Now the vertical spaces are wider; the density is not enough. I can't find a way to make it 'tighter' like I had it before in regular FF. (I don't feel like switching back. Sigh...) Are there some other settings or an app that can make the change I am looking for?

(I can't take a screen shot because as soon as I touch a place away from the drop down, the drop down disappears.)
