After firefox updated all the addons some of them opened a new tab after restarting. That tab reported that each addon had been updated. But those tabs keep opening at startup, hiding my homepage and getting annoying. I have solved many of them downgrading to an older version, but i can't fix the Tabmix plus tab that keeps leading here: http://tmp.garyr.net/version_update2.htm?version=0.4.1.1pre.130722a Even downgrading it, which makes it lead to a different page that explains about a different version (the one i had downgraded to)
