Tabs make lots of sense, windows let me organise them into groups of things I'm currently working on. That's all sensible. Anything I come across that I think might be useful to my future self, I bookmark it. Again, working with the provided functionality. Sensible.
When people have 200 tabs open and can't remember what's where, that's what puzzles me. I've seen people flick through dozens of tabs looking for a piece of documentation they saw yesterday afternoon.
We already have the tools that make browsing and researching efficient. People just need to learn to use them.
The problem with bookmarks for most of us is that users don’t typically manage their bookmarks and delete the links they don’t need.
