If you're proposing that bookmarks are the equivalent of tidy drawers (and a tidy mind), then I wonder, why you think tabs are not.
In Firefox, Bookmarks and Tabs seem quite similar apart from the UI for handling them. However Bookmarks record only the page title and URL, and organising them is so much work that picking up a group of tasks with them is a pain. Whereas Tabs record where you were on the page as well (scroll position), and automatically product a track of grouped, time-ordered tasks that were spawned, which can then be pruned.
(Neither is ideal; I would like to be able to highlight text on a page or a region, to attach a note to remind me what task I've set the page aside to resume later, and to have a fast, sleek UI for reorganising later in a pruning phase. Neither Bookmarks or Tabs provide these things unfortunately, and neither does any extension I've tried so far.)
When a comment above asks what sort of workflow, my answer is that at least there is a workflow. Bookmark land is where tasks go to die because too much context is lost, and not enough is captured automatically.
