Amazing addon. Found this addon after trying different RSS feeders, and found that this one not only worked the best, but has a simple and efficient layout. Don't make an account as the addon will lose functionality and will only give it back if you pay, but luckily not using an account grants all the features, jut import your feed list as a guest and you're good to go! This addon runs a LOT smoother than other feeders I've tried. Also, the developers are very kind, and were quick to reply to me to hep when I had a strange glitch on my addon (That was the only problem I ever had with the addon, and I've been using it for a long time on both Chrome and Firefox). Definitely use this addon, totally worth it, I can't live without it.
