I used this extension for a few months. It worked well enough. However, one day I opened my browser and all my collections were gone. I lost everything that I had saved. Look for something else if you that worries you.
I may be dense, but I don't see how to use this. There's nothing in the hamburder menu nor when you click the ext icon.
