I am on the mozila site too because FF-portable suddenly does the weirdest thing. In short: when I click a link in mail or anywhere else a NEW instance of firefox portable seems to start, with a different profile. Same exe, 2 different profiles from 2 different locations on my pc.

Question from the person that has been very helpful on mozila forums:
I didn't think Firefox Portable could run multiple instances, or that it would ever use a profile outside of its own folders. That would be something new compared with their usual builds. Could you check on their forum whether this is the expected behavior or a bug?
Any help is much appreciated.
