I don't think so, unless they mean that the individual profiles themselves can't be bookmarked. I certainly have about:profiles bookmarked only to make it appear in the URL bar slightly faster when I start typing, but it also does open through the bookmarks menu.

OH! this is super clever after a decade of me typing about:config and other that I never remember completely ! this is so much easier ;p

Yeah, that's become my main use for bookmarks. I prefer to treat the URL bar like a CLI as much as I can, and to not have the bookmarks bar take up space.

Actually, it would be kind of awesome if the URL bar really could act more like a command line for the browser. Hmmm.

interesting maybe this could be done with an extension using the omnibox api...

Seems I was thoroughly misremembering. I guess I was thinking it nice to be able to pin it to New Tab or make it a toolbar button or something, and my brain just compacted that beyond recognition. Sorry for that.
