The portable Firefox version is merely specially configured to run from a removable device and has the profile folder in its installation folder and not in two locations in AppData\Roaming (main;root) and AppData\Local (caches;temporary). The portable version also doesn't use the disk cache and can thus be slower. I don't know whether the portable version supports local storage as this requires storing data of unknown size in the profile folder.

This version doesn't share data with, it works just like the regular Firefox version apart from configuration differences.

Firefox portable could be the first real step in the legal protection of individuality and intimacy, but Moziulla has messed it up like all programmers. Not the Mozlla gives only the smallest amount of data needed to the Microsoft system, no, Mozilla confuses my security by revealing everything and everyone in Microsoft's environment. So a year ago I came across a massive data theft, until then I didn't know how massive Mozilla was at Microsoft. It would be 100% user-friendly to ask the user first if he wants to leave something or even EVERYTHING with the Gates Company. The crime begins when mobile, flexible collaborations are clueless that Mozilla is wasting data on different Windows computers, always leaving all traces of their own workplace. My demand for Mozilla: 100% portable browser and not the real mess
