I'm trying to start Firefox with a profile set up for extension development. I can start a copy of Firefox with the dev profile from the command line but I'm stymied as to how to start it from the menus.
The command line command is firefox -no-remote -P "dev" but no matter how I futzed with the menu entry I can't get firefox to come up using the development profile. It always brings up the Profile Manager even though I've passed along the parameter that ought select a profile.
