Rofi + Firefox, inconsistent behavior

[gorg86]

Hello,

I use Rofi (rofi -show run) regularly with command line options for all kinds of programs, and they always get passed on except for "firefox -P" or "firefox -ProfileManager", lower case p does not work either.
"firefox -P" does not get written in the history either and when I check the command line arguments with ps, it shows me that it did not get passed on, so there seems to be a problem with Rofi.
When I use other arguments like "firefox -url google.com" it works though...
