Hey all, What I want to ask is in the title. Customize does not allow this and neither does dragging. I can put the add-ons button somewhere else but I want to get a specific extension to show up on my toolbar (left of the options hamburger menu). How do I do this? I thought there may not have been enough space at first so I removed another extension, but I still can't put it where I want it. The extension I mean is called "Close other tabs", basically I want it to be clickable and that once clicked, it closes all tabs that aren't my currently active one. I use something like this in chrome and it's really useful. Since I switched to Firefox I want the same thing, but it seems this extension only allows using hotkeys, which is a bit annoying (my brain can only take so many hotkeys and a click-and-fix solution is better for what I want to accomplish here I think) Have a nice day, DiaborMagics
