The latest update increase the font size, which looks nicer to me, although a point or two lower would be fine too. Perhaps an option to set font size would be best to suit all users?
Being able to see all different reddit pages on youtube videos is one of my absolute favorite extensions on a web browser, in order to get different discussions on said videos. On chrome, alientube was good until the dev stopped support; although it was picked up and reworked on github to work wonderfully again.
Switching to firefox, i couldn't get the new alientube to work right, but this extension has been a perfectly good substitute. For a short while i couldn't get it to consistently load on all videos, even when i knew there were reddit pages on a video, they just wouldn't show up. As of recently its been perfect though, and been exactly what i want.
I'm giving it 4 stars as its almost perfect but the occasional error when reddit posts don't show up was frustrating, and a way to change the font/ scale (although i like the bigger size as of today's update)
