With last update, I couldn't open Firefox and Firefox Developer at the same time. I've already seperated profiles enabled, I've already checked the "Allow Firefox Developer Edition and Firefox to run at the same time" but nothing changed.

See if this command makes any difference; firefox.exe -no-remote -new-instance (on each program) Also, make sure each is using its own profile.
