Really well done. Definitely helped me adjust to the switch from Safari to Firefox!

EDIT 1/13/2021: recently the button in the address bar stopped working, so I exported my data and removed then re-added the add-on to see if it would fix anything. Unfortunately it didn't and the exported data is actually missing some of my URLs when I imported it. Is there a better way to reset this add-on to get it working again?

Sometimes my reading list is empty, but if close FF and reload it's back.

This new update doesn't save a page to the reading list when I click the icon several times. It also shows all my pages that I've deleted before

Its a great App. But I hugely miss collating similar content links into Folders/Tags. Else as the number of links grow. It will very difficult to revisit links.

界面和动画都不错,但没有一键清空不方便,因为有时查资料发现更详细的网页那之前暂时存放的就没必要阅读了

the startup animation when opening the pop-up with saved list is ruining this extension. Instead of having a pop-up with known height we get a thing that grow up slowly as the list items animation is fired.
