Agreed.
I'd not say that there's no room for improvement WRT bookmarks and tabs, but this has nothing to do with the comment thread I responded to.
> For example adding a Firefox addon to display tabs vertically in a tree structure instead of a horizontal list has changed the way I use the internet
Sounds interesting, which extension would that be?
Could be Tree Style Tabs (https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...) or Tab Tree (https://addons.mozilla.org/en-US/firefox/addon/tab-tree/).
Yes, I'm using Tree Style Tabs.
In the end tabs are just like booksmarks, except that they keep state during a browsing session. I find it very weird that we keep those very similar concepts in completely different UIs. There's a lot of room for improvement in that area.
