Private browsing means nothing is recorded. Data is stored in the computers RAM during that session. When Firefox is closed, the RAM is flushed.

huh, i didnt know that.

i imagine some things must be stored to the drive, such as flash content? or it would use up all the ram..

That I don't know.

anyone?

I've called the big guys to help you. Good luck.

What plugins are doing is probably not predictable. In PB mode Firefox will try to keep data in memory, but will probably only keep the current part of a file stored in the memory cache requested by a plugin via streaming. Files that are opened in an external application will always be saved to the Windows temp folder.

Note that Windows can decide at any time to page data to the hard drive because that is how virtual memory works when the real physical memory is needed for other tasks or you otherwise run out of physical memory.

so say a user is watching anime on crunchyroll, the videos are streamed to a flash player embedded on the webpage, its likely the data is stored in ram?

but there is a chance it was paged to the drive.

Flash content goes to "temp" files in Windows, Firefox has no control over it in PB mode.
