Thank you for creating there doesn't seem to be any other firefox extension that does this.
It's almost perfect, I'd like to see the following improved.
- Tab buttons don't fit the theme of youtube, they could do with modernizing.
- Tab buttons apear over the tabs content
- Make it more obvious that you can resize the tabs section as I didn't look at the screenshot and at first thought it was stuck using the default view.

It works but reducing the comment section size also cuts the comments. if it can be improved, it will be at its finest!

Such a great extension. I disliked having to scroll down to view comments on a video. Though I would suggest adding a settings as to what the default tab should load first like instead of always having the default active tab as description you could set it to comments or related in the settings. Thanks for this extension.

Whats the point to have comments on the right if, when scrolling, video goes up off the screen too.

Thank you for porting this extension for Firefox. You've no idea how long I was waiting for this. This extension is one of the reasons why I stuck with Chrome and now I don't have to.
