I expect that the browser takes more memory resources, but my impression is that Firefox doesn't set up a page/tab until I look at it. Until then, it's (mostly) just a potential page, I think. When I close Firefox, it remembers all of the tabs, and lists them when I restart, but I think it doesn't do anything with a tab until I switch to it. Now, I have a number of ad-blockers, script-blockers, and so forth, and when I enable a site which was disabled, I've noticed that Firefox reloads all of the pages that have content from that site. So if, when I restart Firefox, I don't have content from wikia.com enabled, I might have a couple of dozen wikia tabs in my browser. But they don't use resources until I switch to them  If I then enable content from wikia.com, only the tabs that I've looked at are reloaded to reflect the newly-accessible content. I think. I need to check that.
