At the moment I'm using FireFox 3.6, but have tried Google Chrome beta. The thing that I like about FireFox is that I can set it to clear cookies/history/etc. on exit. I've tried to do the same thing in Chrome, but ran into a problem - It appears that Chrome stores its add-on settings in history/cache somewhere, so each time I exit, some of the add-ons lose their settings, and I have to reconfigure them when I open the application. Is there any way around this?
