Now to test the websites I use multiple virtual machines (VirtualBox) with Web browsers.
I want to make portable versions of browsers (to collect IE, Opera, Safari, FF, Chrome and maybe another). I want that browser have development tool (e.g. like Firebug).
For virtualization apps I found several solutions: BoxedApp,Cameyo,JauntePE
Spoon Studio / Xenocode Virtual Application Studio
MoleBox Virtualization Solution
Tell me what there are and what should I choose for my task?
