Both together

Hey.

I discovered, and I want to share, a way to start simultaneously two firefox (Regardless of the version or profile).

For example, I have the third beta for surfing, and the second version with Firebug , LiveHTTPHeaders , Operator , FireFTP , Web Developer Toolbar - for special needs.

Write the following in a baht file :
@echo off
set MOZ_NO_REMOTE=1
start "" "C:\Program Files\Mozilla Firefox\firefox.exe" -p
set MOZ_NO_REMOTE=0
