For years, portableapps and firefox has been such an amazing combination, I've been using it for years across linux and windows - working perfectly, and then oneday I had to use windows vista - crash bang!
My portable flash drive works perfectly on XP and linux, but not vista.
I launch from a batch file with a simple [firefox -P] command and then have a profile in a directory called [NuFox]
Out of habit, I always make my flash drive as [E:] So when I get to a windows machine I do this
And then choose my profile on
I'm guessing there's a vista permission issue here or something ...
when I launch from vista - it just loads a plain firefox, with no extensions ... it seems to be creating *another* blank profile inside the existing profile directory ... so what I get is
If you can work this out, you're a better person than me for sure!
