To be fair, Firefox starts up quickly even with hundreds of tabs saved, because only the pinned and current tabs are loaded on start. I used to think it was awesome how it kept memory use efficient by leaving unused tabs unloaded, but it has gotten too good. I use Sidebery to classify my dozens of dormant tabs, but the net weekly balance is a few tabs positive because I've become less selective with this power.
