> That and the fact bookmark may ends up in a removed page, orphan link.

Except in the immediate short-term, keeping a tab open doesn't really fully help in that regard, though – even if the browser doesn't autonomously unloads tabs, sooner or later most people will eventually need to restart the browser and/or computer for updates, old pages are eventually evicted from the browser cache, and so tabs suffer from link rot just the same as bookmarks do.

For me the benefit of using tabs over bookmarks is that from the order of the tabs you can figure out what you were doing at the time. With tabs it's also quicker to go back later and close what you no longer need.
