Question

Is it possible to set session variables or cookies that will exist across all tabs?

I thought firefox kept session across all existing tabs, however im testing and finding that only the current tab where the session was originally set is the session available.

Thanks!

EDIT:

Tab 1:

setcookie("testcookie", "something", time()+(60*60*24*365));

Tab 2:

print_r($_COOKIE['testcookie']);

Tab 2 only prints an empty array. If I move this to tab 1, it will print out the cookie.

Answer 1

Cookies are always sent to the server providing that:

• The domain matches (including sub-domain).
• The path matches (cookies can be assigned to specific path — assigning them to root means the entire domain).
• The port matches.
• The protocol (http/https) matches if you set the cookie as secure.

As long as all those things are true, you should have your cookie / cookie based session on all tabs. You will need to refresh the tab in order to see any effects of the cookie (including seeing it in Javascript of Firefox extensions).

If all those are true and you are still not seeing your cookie on all tabs then you have a lot of debugging to do… that is not standard behavior.
