Awesome extension! Actually works (unlike official Wikimedia firefox extension) and gives you feedback with a little bookmark icon if you've already added an item to a Reading List before.

This extension lets you edit Reading List names which I was struggling to do in the iOS app itself. Very powerful tool that seems to be updated regularly, looks like the developer updated yesterday, dope. Highly recommend this for people trying to add items to their reading list on Android/iOS from Desktop!
