Is this normal for a browser?

I know Chrome would be a lot more.

Not sure about a lot more but it would be somewhat higher on Chrome.

Looks pretty normal considering the number of youtube tabs you have open (if we're talking about memory usage here).

Yes I am talking about memory usage.

Depends on what extra addons/mods you have installed in FireFox.
