I am experiencing weird problems with Firefox however, how do I reset Firefox completely, deleting everything I once did with it, so when I open it, it is like I just installed Firefox for the first time?
 
Drag the app and all associated folders into the trash, then do a reinstall. Save your bookmarks first, though.
 
The associated files other than the app itself:
  • ~/Library/Application Support/Firefox/
  • ~/Library/Preferences/org.mozilla.firefox.plist
The ~ refers to your home directory.
