Comment Re:Multiple Profiles are More Functional (Score 1) 186
I do this on ubuntu, and it seems to work:
firefox -no-remote --ProfileManager
It's useful for me because I like to use non-standard color settings, but there are sites that are unusable if you don't let them set their own colors. (It'd be nice if there were a better solution, but switching profiles as necessary is what I've been living with.)
