406952 - Session restore should remember cookies

Status: RESOLVED WORKSFORME

(Firefox :: Session Restore, defect)

Description

[Jez]

I actually have the opposite complaint to bug #345345.

I find that the 'restore session' feature of Firefox, offered when Firefox has crashed previously, forgets session cookies that were keeping you logged in to things previously; for example, Squirrelmail will just return to a login screen upon session restore, which is annoying.  Could we add the ability for FF to truly restore the session upon session restore?  If it is remembering cookies, why is it being logged out of Squirrelmail?

After IRC discussion, it would appear that this only happens for sites using HTTPS.  Why?  I don't think it should, as the expectation with this session restore (after FF has crashed) is surely that the user will immediately start FF up again, and logging in to all previous sessions is useful.

The reason is privacy: We wouldn't want people to accidentally remain logged into their bank accounts. So in the same way we write data transmitted via https to the disk cache, we don't write cookies, etc. related to them to disk.

Setting the hidden pref browser.sessionstore.privacy_level to 0 will make Firefox behave as you want, though. -> WORKSFORME

P.S.: Before filing a new bug to have the default value for that pref switched, please discuss the implications over at the mozilla.dev.apps.firefox newsgroup.
