unfortunately doesn't work when YouTube redirects page to m.youtube.com.
i get my internet through my cell phone.

Great Experience but doesn't override some of the more recent changes such as description box placements. I hope an update comes that changes that.

Yeah it used to be nicely separated in sections like "recommended for you", "popular in your country" or other topics. There is no grouping anymore, just an endless stream of thumbnails (in 6 columns, admittedly). Also the side panel used to be closed/minimised by default. The only thing that changed is that I updated the browser (and add-ons).

This is a good extension but when i try to change the logo on Firefox 56 it just dosen't work. Why!? Also please add more minor old features, like the like and dislike button.

Its decent enough, but it WILL NOT SAVE the number of videos in the main youtube screen. I set it to five, and it always defaults to 6, no matter how many times i reinstall the addon, or restart firefox. So just be aware it does have its issues.
