What I'd like to do is be able to use both at once, by isolating the tab's cookies from each other.
I tried using the IE-Tab extension, which acheives this seperation by embedding the other application's viewport while keeping it's runtime environment seperate.
But Internet Explorer doesn't use a master password, or implement any sort of password security for that matter- so it's not an option.
The best I can come up with is to open 2 seperate Firefox windows, each using different profiles, but then I couldn't just change tabs to move between accounts.
Does anyone know how to implement a solution to this?
Preferably to work with Firefox 4 beta 7, which is what I'm running at the moment.
