The way people use tabs is bizarre to me. My ex would have so many open that it was really difficult to navigate between them. Seems like a better idea to use features like bookmarks or reading list.
I do programming and I need access to project management sites, communication sites, documetations (language and library) and tools sites opened.
When I am researching the topics I am not very familiar I usually read 4 or 5 sources. So in the middle of developing a feature I have at least tens of tabs.
When it combined with home lab servers, entainments, side readings and related readings I usually tends to end up with hundreds.
I used to have 20-30 open at a time when I was doing the same things, but I can't imagine building up to hundreds. Maybe I'd leave them open for the next day, but generally I try to stay more organized than that. When you have hundreds of tabs open you can't even see the titles so I find it a lot more difficult to navigate between them.
