What are the best browser extensions for organising & tagging bookmarks?

I will go ahead and shamelessly mention the solution I have been working on. :) We are always working on shipping improvements and making sure our current 6,000+ users are happy with the extension. If you are looking for a bookmark and tabs manager, and you are familiar with boards and columns similar to Trello, Qlearly might be the solution for you!

It's the best one that I've found so far. I used delicious for years and I really liked it. Raindrop seems to be the best replacement. One issue is that I want the default sort to be reverse chronological order and I can't figure out how to do that.

Can’t remember the rebranded name off hand, but I hunted these guys awhile back and it’s amazing. Definitely check them out. Super polished product.

This thing is a gift. I know all of you have 50 tabs open right now of things that you'll be reading later - but you don't know when later is. That's when Toby comes in - you can save things into a session and view them later, whenever you want!

Simple, concise, effective.
