I started tabbed browsing with Opera 5. It was amazing then back when I could do 50 tabs, and it's amazing now with firefox forks when I can do 500 tabs with less than 3GB of ram used (with Noscript on for most websites not whitelisted). But don't try this in a multi-process browser, not even modern Firefox can handle truly large session files like Palemoon or Seamonkey classic can. I have saved my Opera->Firefox->Palemoon session files at least every month since 2003. I have a little perl script for converting any of their session file formats to a number of tabs (http://superkuh.com/opera-sessions-to-tab-number.pl.txt http://superkuh.com/opera-sessions-to-tab-number.pl.txt). Using it I can plot the number of tabs in my browser over 20 years. But that's just trivial visualization. I still find my old session files valuable in other ways.
