I currently have 753 tabs open on this computer alone :p But as you say, it's not a problem at all because there are not loaded until I go back to them.

The only issue I have with massive number of tabs, is the start-up time of the browser, which increase dramatically with the number of tabs (it's at least quadratic).

The only solution to this would be effective treatment for ADHD I think

Did you count them? How can you be so exact?

If you try and close the window, firefox will be default warn you and tell you how many tabs you have.
