All in all I am happy with using Raindrop.io, but recently the add-on won't work anymore. It gives me 404 error. The web version and the native desktop version work though.
Edit: Nice that it's working again!

一直用，非常好

love it! it keeps getting better and better!

Con una interfaz supremamente cuidada, y caracterìsticas gratuitas razonables. Me ha encantado la extensión.

The best bookmarking tool except for pocket that costs considerably more. ☻ No joke.

Bdah

This is an incredible application! I love it at the first time I tried. Please don't stop keeping it stable and adding more rad features in the future.

easy to use

how to link with firefox Android app

Good job, guys!

I love this extension! I was looking for it for a while to have my bookmarks in all of my browsers and devices.
I don't know why "Speed Dial" does not work on Firefox.

This add-on is outstanding. After trying many script/memory/disk space heavy alternatives to simple bookmarking - happening upon Raindrop.io was very satisfying. As a business operator with countless resources to monitor from economics, law/regulatory changes, supplier websites and everything in between - Raindrop.io has made bookmarking as simple as the classic NetScape implementation of "bookmarks" and added a visually elegant UI with low requirements, and easy navigation/functionality.

I can't recommend Raindrop.io enough! The price is reasonable as well - and there is nothing that makes you itch for the paid version - although people with many, many websites to keep up with will find the subscription to be a great productivity asset. In any case it's always nice to support open source software with a donation!

Very Nice Work, Rustem Mussabekov!

I was looking for something like this really long time. I tried many other solutions, commercial or open source, but now I am happy. There are some very small problems in rendering under some conditions but it does not matter.
