If it is the 3 dash line then you can't remove it.

Can you attach a screenshot to show what button this is about?

I want to the remove the Menu Button from the toolbar on FF Quantum. When I right click on it "remove from toolbar" is greyed out. I do not use it and would like it gone. Thank you.

If you are talking about the '3-bar' menu (Firefox menu) - the three horizontal lines right under the closing 'X' - you should be absolutely sure that that's what you want to do, cause after that, the only way to access 'Options' is to press the Alt key => Tools.

If that is what you are talking about, and you are sure, please take a look at how to do this using userChrome.css :

Thanks. I should've have mentioned that I'm on a mac, so the bolded part of your answer doesn't apply in my case. On a mac, you can access all of the options from the drop down menus at the top of the screen. That's what I've been doing ever since I started using FF (long, long ago) and I'm really not interested in having the menu on off to the side.

No, my bad - I should have realized that maybe on Mac this works differently (your system details show that you're on Mac .... ).

I'm glad this works for you, though  !
