i am a beginner in computer science, and i am facing a problem with firefox cookies..

I am trying to create a cookie with sqlite but it doesn't work. This is what i did:

sqlite3 .mozilla/firefox/profile.default/cookies.sqlite

//then, i create the cookie//
sqlite> INSERT INTO moz_cookies VALUES (NULL,"test","blablablabla",

//lets see if it worked//
sqlite> SELECT * FROM moz_cookies;

//yes it works//

BUT ! the problem is that when I lunch firefox and when I try to see the different cookies for .remote-exploit.org, nothing. No cookies have been created ???

If someone could help me, this would be grate !
