I'm glad to find Firefox Portable. I believed something like that must exist. I would like to take my Firefox with my bookmarks and saved passwords everywhere with me on a USB flash disc. It will come in really handy especially on vacation, surfing the net in NetCafes.
I'm going to buy a USB flash disc on which I'll be using my Firefox Portable. I'd like to buy this one: http://www.westerndigital.com/en/products/Products.asp?DriveID=226
6GB USB flash / external disc and I can have it for as low as ~$40 only (I think it's a great price for a 6GB flash disc). However, this flash (external) drive has only 3,600 RPM (nominal) rotational speed. Won't it slow down my Firefox Portable?
Shall I rather buy a standard Corsair or A-Data flash drive? But these are more expensive.
