I gave up on bookmarks in normal web browsers. (I still use them on my phone.)
I have five or six permanent tab-pins in each of Firefox and Chrome, and about two hundred open tabs at any given time. Add in search engines and history suggestions, and I'm covered.
It would be nice if unused tabs gradually migrated to a bookmark list, I suppose, but we're already most of the way there with late-loading tabs.
Wait... you mention Chrome... and two hundred tabs open. Given that Chrome (very intentionally) becomes unusable before you get to 15 tabs even on gigantic widescreen monitors, how does Chrome manage to remain in your stable of browsers? I'm in the many-tabs crowd, but not so much to replace bookmarks. Bookmarks to me are 'this is a resource I will probably need later... likely much later'. Open tabs are 'I want to read this soon', and soon might be weeks later (though I usually get time to read on the weekends).
I gave up on Chrome when they took their perfectly usable vertical tabs implementation (which was an experimental feature you had to enable manually through the about:config page at the time) and just tore it out one day for no reason better than 'eh, we dont think that was a good design'. There weren't any problems with it. It wasn't holding back the development of anything else. Just some random dude at Google got a bug up his ass and decided to destroy Chromes usability for a few thousand users. And, of course, thanks to the whole invisible upgrade 'feature', the application just became unusable overnight with no mention.
Personally, I want the solution I've wanted for a very long time - tabs that remain open. Forever. At least, that is how it should LOOK, with the intelligent swapping and like going on in the background. When Firefox came out with the fullscreen tab manager with tab groups and everything I was so psyched.... and then I found out that Firefox actually keeps ALL of those tabs in memory. And you can't close a group and come back to it later. Useless.
I don't push 200, but 80 isn't rare for me (going by TooManyTabs extension count). IME, Firefox slows down much faster than Chrome when browsing this way (on Win7-64 w/ 4-8GB of RAM).
Do you know about the 'load tabs on demand' feature shipped in firefox 13?
I usually leave tabs to read later open and restart my browser each morning. This way only tabs I visit that day will be in memory.
Maybe there should be a dormant tab-space, like on the left side of the browser. If you drag a tab there, it disappears in. Then, you can drag-move or drag-copy (to not lose its place in the bookmark space) back to the live tabs. Maybe give it multiple rows, which you can label (or not).
