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?

It shouldn't be a big difference, but additional window is an additional memory overhead.

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.

You can check the about:memory and about:processes pages for info about all processes. See also the about:unloads page for info about the tabs.
