Two column addon display not compact enough.

I too was disappointed in Mozilla continually adding more mouse clicks, more white space and additional display of unwanted or unnecessary information. I have posted compact four column addons display scripts on Aris-t2's Github site. Go Here! Aris-t2 scripts for buttons required. I will definitely look for inspiration in your other Firefox css-hacks.

I'm not sure what exactly it is you are asking here.

At any rate, I created two additional styles affecting addons-manager.

compact_addons_manager.css makes installed addons list more compact. Not quite to the extent seen in your screenshot but a lot more than two_column_addons.css

addons_manage_button_without_popup.css does pretty much what the name says. It works on it's own but is also compatible with both two_column_addons.css and with compact_addons_manager.css though you may want to use a compatibility rules found inside addons_manage_button_without_popup.css depending on how wide your window is (commented out by defult)

@MrOtherGuy I noticed your recent posting of the grid based addons manager. Thanks & Bravo! My column based addons manager has a conflict with Nightly & Aris's buttons, so I gave yours a try, I have a bad habit of tinkering and ended up with a hybrid of your manager and Aris-t2 system. It still needs some polish but is workable with Firefox Nightly 72. To view properly, I set about:addons to display at 80%. Grid_addons.zip

So, there isn't any remaining issues I guess? At any rate, you may have better luck with my manage buttons without popoup than with aris's version, not saying aris' one is bad, just that it may not be compatible with the multi-column stylesheet from this repo.
