That's because the bookmarkers sucks. They do not adapt to what you are doing, you need to do a lot of setup and organize a lot to be able to use it well. It should be more organic, grow with the use you make. I still believe that anyone who makes a better bookmark will dominate more than just the browser war.
Bookmarking always struck me as a 90s solution to just having fulltext search and analytics over your browser history, there have been a few attempts at browsers that addressed this head-on, but they've all died off over time
IMO just one good new tab UI over a user's history/local cache could make a sizeable dent in Google's ad revenue
Opera with its unique cache offered the option to have full text search in history and it was great. Then quarterly profit became a priority for the board and they dropped their browser to become a google chrome advanced skin.
How do you organise tabs then? I've god knows how many bookmarks and I've been blindly Ctrl-D-ing since time immemorial, only tagging very distinct stuff and modifying titles if too stupid. When I need to get at sth. bookmarked, typing stuff into the url field in firefox just works.
Well. I've made a little extension that lists unread links. For linkrot, yes that's an issue I plan to solve, and what I will do is I'll either find or write a program that saves my bookmarks as websaves.
Have you tried pocket? I used to keep a load of bookmarks but the problem was that after a while many of the source urls would die off. So something like pocket is very handy as it takes a copy of the page you're interested in.
Pocket had a great integration with Firefox when it was an extension. Then they decided to integrate it into the browser and ironically it end up being a piece of shit that was not more functional than a bookmarklet. Not only that but they also removed the original extension from add-ons site so you have had to use the half assed built-in implementation.
