As an example: suppose you have 100 tabs open. Does Firefox use more memory if 50 are open in 1 window and 50 in another or if all are open in just 1 window? Does it make any difference?

Thanks for your reply but "additional window is an additional memory overhead" was assumed. Hoped someone would be able to be more specific ei. percentages, etc.
