I had firefox open. Then the program collapsed. The program was closed. I am asking if there is any solution for finding sessions. I already tried restore previous session and it does not work. Thanx for answer.
Not even with some software. I know they are some software that can sometimes regenerate files, even when you delete them. Is here absolutely no chances?
Yeah it's gone. Nothing you can do. As Beers said the file is stored in your RAM when in use. Depending on how the program manages it's memory it will most likely release the RAM it was holding once the program was closed and thus "forget" where you were. Restarting your machine also clears your RAM.
Also it will be in your browsing history unless you clear it or have it set up to not keep track of what you do. If there was stuff that was previously filled out on the page you were on and that's what you needed back then the website MIGHT have autosaved it for you upon leaving and if you navigate back to the page it will still be there. I wouldn't bet on it though as this isn't that common.
