What an amazing extension is this. My YouTube is now blazingly fast. Please keep doing the good work in the name of Humanity that companies like google fails because they prioritize profits over people. This extension also made YouTube on Firefox faster because google is known to slow down YouTube on non-chromium based browsers through their Polymer JS framework.

Cant change terrible large videoplayer UI back to old one. Only thing I downloaded it for.

Very good extension that makes the UI much easier to wrangle, but it sometimes disables the ability to pop out the video from the tab which is very annoying. Otherwise really good product.
(If I'm just missing a setting then I am really sorry)

Great add-on, removes much of the ugliness that the "modern" UI tries to force on you.

If I could make a request, could you add the option to hide the "includes paid promotion" pop-up that appears when you hover over certain thumbnails? With the smaller thumbnails that this add-on gives you, it makes it very easy to accidentally click that pop-up instead of the video when you want to watch something.

just no

Hated so much the new icons that I actually wanted to use this type of extension. YouTube is getting trashier by the year.

This add-on would be good... if it actually would modify the video loader. The new video loader with huge buttons looks weird with the old YouTube UI. Other than, everything else seems to work fine.

This addon modifies a lot of things on Youtube's pages, but I only consider one of those changes a good thing. The others are odd, or even bad.

First the positive one: it allows you to view more thumbnails on the mainpage. That's great!

However, along with that singular positive thing, comes a lot of questionable ones. For example, the default settings make everything about the page layouts look older, less modern, even ugly. Why is that? And even though you can disable some of these changes, there are things that it messes up permanently. Like the latest Youtube posts. They get truncated to just a few words each, and there is no option to change that behaviour. Also, playlist thumbnails are unaffected (= remain huge) despite everything else shrinking. The layouts just become erratic and mismatched.

I would not recommend this addon. If you just want to see more video thumbnails on Youtube's main page, there are better ways to achieve that.

An extremely useful addition to the youtube experience, although I really wish you could change the video player itself with it.

I really like it, that's all

we need new update with old UI!

Not only gave me the possibility of going back to a more usable, nostalgic and overall better looking UI but surprisingly also made youtube to work better and load faster in most instances - in the process making even more evident how much of a bad job the people behind YT are doing with all the bloat "updates" and terrible design choices. Great, great add-on

Looks good, stream viewer count doesn't automatically update though

It's damn great, I wouldn't go on youtube without it!

The community posts have cyclinder boxes (not sqaure) and the icon that shows someone (or a channel) that there live is circular, 5 stars to fix ;)

I understand that the latest update requires permission to be able to export the configuration files, but I beg you, make it optional. Until then I will be forced, for safety reasons, to remove the addon. It is a shame because I really loved this extension.

edit:
Thank you for your quick response and understanding. Reverting back to 5 stars. Thanks for making YouTube usable again.
