Every time I launch Firefox and go visiting some websites, I notice it freezes for about 10 seconds. Not always in the same websites, but it always happens sometime in the first 2 or 3 minutes of running. I can see the hard disk led is ON all the time the browser is hung.
My operating system is Linux and I don't currently have any extension/plugin installed here.
I have no form completion, no history and have no more than 20-30 bookmarks.
Has somebody noticed something similar, or know how can I debug this to find out what Firefox is doing or trying to do?
