Where are firefox cookies in Linux?

I want to find out where are firefox cookies getting stored in Linux. there is a similar old question here which says that the cookies are stored at ~.mozilla/firefox//cookies.sqlite but i think this is not true anymore because i remove this file but i still have cookies in firefox itself. also i tested the entire ~.mozilla/firefox folder with inotifywait using the following command:

$ inotifywait -mr .mozilla/firefox -e open -e access -e modify

and got nothing!. not even an access event occur when i open firefox and search or open any sites.
