I use bookmarks too. The way it works is that while I read I open up links and make notes as I work my way through a page, by the time I'm done there is a few lines added to the notebook and maybe a few new tabs open. Little by little I exhaust the subject and at some point all the links on the subject are already visited. A bit like a human crawler. But the peaks in the middle are easily in the 100's of tabs. This is the most efficient way that I've found, bookmarking works but then you will still need to open those bookmarks later, much easier to just open the tab right away.

It's very much a paper analogy, highlight the interesting bits, add new stuff to the 'to read' stack, and when the 'to read' stack is empty you're done and the notes file contains the extracted information.

The note taking extension I use is called scrapbook and I couldn't live without it. I also use vertical tabs which makes it much easier to work with large numbers of tabs.

If I put them in a bookmark I'll likely never look at them again.

If you use both tree style tabs (which, apart from stacking tabs vertically, lets you collapse tab trees if you desire, and the trees are naturally topic-oriented) and tab groups (a built-in feature, good for splitting tabs by topic), you can easily have hundreds of tabs on the go.

Tabs are sort of a halfway house to bookmarks for me. They persist across browser restarts, but the fact that they are still open increases the chances that I'll consume the information in them.

bookmarks have been broken for quite a number of years now. UX is terrible and irrelevant to my workflow. I use two browsers with 100-150 tabs each and session management is lacking in web browsers. I use the sidebar and tab grouping to keep track.

My solution was to add a 8GB stick of RAM with the usual disabling of javascript by default, no iframes allowed and no flash installed with adblock and fanboy's lists.
