It would be very useful for tech support if Portable Firefox could run from a non-writable media like a CDR, writing its settings to %temp% (don't keeping them).
Thanks for the good work!

I haven't moved it to the new site yet. It's also going to have a major update soon adding in compatibilty for Win9x and ditching the batch file.
Sometimes, the impossible can become possible, if you're awesome!
Thanks! also, running from Win9X is very useful.
Keep the good work!
