I have a massive tab problem, and had to build a personal SOP to manage it. I have 400+ tabs open on Chrome right now, on my mobile. Every now and then, I use chrome on my laptop to open all tabs from my mobile (tabs from other devices show in History), save them to one tab (browser extension), and save it as a HTML, and close all tabs on my mobile. It doesn't take more than a week to build up to more than 100 again.

I believe my record has been 1100+ tabs on Chrome, and 5000+ tabs on Opera Mobile.

The desktop version of these apps can't handle these amounts nearly as well..
