Firefox Temp files

Question

I am in the middle of creating a CCleaner like application for unix based/styled systems.

I am having trouble finding out exactly where Firefox holds its temporary files, and those in the Firefox dev community don't seem to willing to help me find out where.

I know atleast in Linux(which is my focus now), the temp files are held in

/home/user/.mozilla/firefox/*.default/

Most of the temp files are held in the Cache directory, but not all. So do any of you have any tips or documentation of where extacly the temp files are stored.

Answer 1

Usually, you have ~/.mozilla/firefox/profile.default/Cache to hold your cache, but you can also check the location set by browser.cache.disk.parent_directory.

You can find the user.js or/and prefs.js in the user's current directory (~/.mozilla/firefox/profile.default/).

Answer 2

Firefox on windows use SQLLite to store history and such like and i use code to kill the FireFox process and then it deletes all but one of the sqllite files so that you don't losse bookmarks.
