I'm having a similar problem. Whenever I create a new tab and then pick my home button, which is set to iGoogle, I get the "Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page." message.

Below this message, the table shows a list with 'Window 1' and a Monster.com webpage. I assume this is 1 Window and 1 tab. Below the table are buttons for 'Restore' or 'Start New Session' options.

This also happens after I try creating a new Window with Firefox.

I've tried restoring and starting a new session and this just won't go away. Every time I pick my home button or create a new window it comes back.

My firefox is taking too long to open altogether. Why is that? I can't seem to get to other websites. I'm in my mailbox and if anything that requires another tab, it's stuck. I'm all of ready to throw firefox off my computer.
