I was finding infos about what I can do to modified my Bamboo Feed Reader on Waterfox 56 v2019.10 and then this showed up.

I gave it a try and I love it!

I've been a user of Brief and Bamboo and I can firmly say Feedbro nailed it. No annoying auto page scrolling, no weird right click behavior. It shows like a regular webpage instead of a chrome tab. I can copy all links on one page with other addons like copyLinks and it works just fine.

Fantastic!
