Why firefox do this??

why firefox is reopening continuosly this site (http://aos.avast.com/upgrade/2006) on every startup???
If I disable AOS plug-in this doesn’t happens.

It does it every time I clear my browser history.

That’s because AOS stores settings in a cookie. By deleting history you also clear that cookie. Add it to exception list if possible.

Thanks for reply RejZoR. Can you tell me how can i do this in firefox?

Storing your addon data in a Cooky is a realy bad solution. I prefer to delete everything unnecessary when I close my browser. So to fix this I got the options to not delete cookies at the end at all, to install a third plugin to handle cookies oder to disable your plugin.

Well done, realy.

How is it that other plugins work fine without issues like that!?!?! Sorry but in this way I won’t use AOS.
