But why open so many tabs when you can just search history or bookmark (in FF you can also tag by double clicking the star icon)

Usually I find everything I needed by time, data, keyword, tag, or bookmark in a few seconds at most by opening history or bookmark by keyboard shortcut.

In my case I think I got used to have specific ff windows for specific stuff, and having the tabs "opened" feels quicker for me. But I guess I could get used to and switch to tags and bookmarking as you said.
