Running two Firefox profiles simultaneously

In: Browsers|Mozilla

1 Mar 2007

At yesterday’s WebSG meetup, someone asked me how you can have 2 different user sessions in Firefox, and I was unable to answer as I never had the need for 2 different user sessions (though I imagine it’d be nice for testing certain types of interactive web applications).

Anyway, I found the answer today after some Googling – Lifehacker’s “Manage multiple Firefox profiles” article.

Basically, once you have started Firefox in a profile that you want, you can start another profile by passing the ‘-no-remote’ switch together with the name of the profile you want to start with the ‘-P’ switch:

/path/to/firefox -P profile_name -no-remote

It does mean you need 2 different profiles though, for the 2 different user sessions. Oh well.

At first, I was wondering if I was the only one in the room who didn’t know the tricks (I knew about CTRL-T, CTRL-W but that’s about it). Then later I found out you were the author of the book. Alamak! Why didn’t Lucian tell me earlier?! I would have grabbed copies from the library and got you to sign them. Err… the library has them right? (frantically searches for it…) Cheers!
