Emulates the Windows 10 context menus in Firefox.Project mention: Make Bookmark Toolbar Drop-down and Selection Match Theme | reddit.com/r/FirefoxCSS | 2021-03-11
if you wanna save some time styling this stuff, I'd suggest just reading through the stylesheet I just sent you and testing the rules to see how they affect it. keep in mind there are variables in there for colors and stuff, the variables are set in uc-variables.css on the same repo. I'd just replace them unless you're gonna use the whole thing. you can also do the same kinda thing with this stylesheet, it's of a similar scope to mine but with a different style. I think it might be missing a couple of the newer context menus though, so if you're going to use the selectors from one of these, I would suggest using my selectors. I update this repo pretty frequently and new context menu stuff gets added to firefox pretty frequently too.
