Oops or 'what is the maximum number of Firefox tabs I should have open at any one time?'

It would seem that 140 Firefox tabs is too many to have open. Last night Firefox crashed taking Windows Explorer with it. Oddly it asked me if I wanted to save the 140 tabs for when I restarted Firefox, I said yes but Firefox was only teasing me as when it restarted I had just the start up page.

So this morning I have a faster laptop and Firefox is simply zooming along but I have lost the basis of at least 10 articles... As a result I am not happy and blogging may be light today.
