Impossible. ?!
Portable Firefox 2.0 is a stuff-up:
1. None of the ini files are the same
2. Everything's different.
3. You can't run PFF while another instance of firefox is running.
I ask you then: WHAT IS THE POINT?
Why not code a batch file that copies your profile over everytime you run it, on whatever computer, wherever?!
PFF2 should have it's own forum, if it's so different. It is so utterly frustrating to see an application with so much potential so stuffed up due to shortsighted planning. The do-gooders coding it should just all die.
I have one simple requirement: I need to launch as many independent instances of firefox 2 as possible, without any interference between them.
