75+ tabs are only feasible if you have an extension like Tree Tabs for Firefox. Of course, no more than ten (at the most) are ever loaded into memory at any one time.
The true shame is that trees of tabs aren’t natively implemented by the browsers because all the extensions that enable tree functionality have glitches caused by the native tab ordering.
I beg to differ. I have, in a vanilla firefox UI, about 100 tabs, in a single window.
I group them (loosely) by their themes, in the bar. It's... manageable.
