Menu font change in FF for Mac

Looking for an add-on to increase font size in menus and tabs for FF 124 for Mac.
There was Font and Size Changer, no longer working since many years.
Is there another add-on?

To my knowledge it’s no longer possible for an add-on to change the size of text in Firefox menus. I tried a few web searches and I couldn’t find a direct solution for your issue. This Mozilla Connect thread looks like it may be relevant; you may want to give it an upvote.
