Firefox dropping out?

[harm_less]

Are there any other Firefox users out there who have had this browser totally drop all tabs including logging out of those websites that require a log in? This has happened every couple of days to me over the past couple of weeks for no apparent reason. This evening it was a couple of times while relisting Trade Me items.

only thing I noticed was it has asked me recently to enable "total cookie protection" - maybe that is causing it for you...
I don't really use FF for much at the moment, so can't really speak to the impact of it when logged in anywhere.
In the settings search for cookies, it's listed under "Test pilot our most powerful privacy feature ever"
