cache i know how to clear them..
but stored file ? how ?

Firefox -> Options -> Advanced -> Network
here you can clear saved webconten (cache) and you can clear offline webconten (stored files)

i already do that
but same problem
i Open FF as Private, working..
is there any option to remove all my things from FF(emails, passwords,sites, etc etc.. )

^ removing all those things from firefox browser is not required.
just try hard refreshing browser a couple of times (eg. press CTRL + F5)

and / or clear forum cookies through link available at forum help section
close browser, reopen it and try again login process

No not working like that
the thing that will solve my problem is to remove everything from ff..
how to do that between ? :v

You can completly reinstall it with a new profile and hold your old profile as backup:

Open
%APPDATA%
And then rename the Mozilla folder to OldMozilla (I suggest renaming instead of deleting so you can dig out anything essential you need later)
Then edit the "Roaming" in the Windows Explorer address bar to "Local" and rename the Mozilla folder there the same way.
Then when you run the installer, Firefox should not detect your old settings and should instead set up new folders.

install it again!! nah i wont do that..
i want only something to remove DATA Saved...
