Description from store
Fix YouTube thumbnail size by changing the number of columns on YouTube homepage and subscription pages. Fixes YouTube's dumb HUGE THUMBNAILS rollout. Allows you to change the number of thumbnails appearing in each row on your YouTube feed and subscribed channels.
For some strange reason YouTube only shows 3 videos per row, sometimes only 2 videos per row. (depends on browser size). I found this to be a terrible experience and decided to make an extension to fix it.
Just install. Set the desired number of thumbnails per row (or videos per row -- however you want to describe that!)
If it works for you, I'd sure appreciate a review or rating! Thank you!
