Is it possible to hide the buttons but still use the addons

I want to be able to use my themes to the maximum but to do so I would need to remove some of my add-ons if not all of them. I just installed a really cute theme and I can only see about half of it thank to the add-ons I use everyday. I don’t want to remove the add-ons just hide there buttons. Is it possible to put all the buttons into one button or a way to hide them until you hover over them or something like this. If this is possible to do in firefox please let me know thank you.

Right click on the toolbar → Customize… and then you can drag the icons wherever you want them.

You can also right click on a specific icon and then select “Pin to Overflow Menu”.

If you are interesting in pursuing some kind of hover magic, this is a good subreddit to seek custom style rules (to put in a userChrome.css file):
