Deleting Cookies from Firefox on OS X?
How do I delete cookies from Firefox on Os X? My boyfriend re-installed Firefox on my mac book pro, and previously every time I ended Firefox, I was given a checklist of options that I wanted cleared.
I read on Firefox’s site to go the Task Menu, however, I don’t have that option on mine. I understand that under Tools, there is an option that says, “Clear Private Data,” does this include cookies, if so, is there a way to customize it to include cookie deletion for future reference?
Thank you!
Haha, nevermind!! I got it, I went to the Firefox Tab> Preferences> Privacy. : )
im not quite sure for mac but if you click Clear Private Data than it (for PC) comes up with a little box that has a list and check boxes so you can choose what you want erased. thats how it is for PC
as i said im not sure how it exactly works for mac
