ImprovedTube is a YouTube Extension for all Browsers, that modifies video player & Youtube to give users more control over all aspects of playback & Youtube site. With ImprovedTube, you can adjust the permanent size of the Players and automate if the video description is expanded by default or hide related videos to avoid distractions; make playlists play reverse, or fix video quality. And many other options. We created our YouTube Extensions carefully to make sure all existing YouTube features function properly and without issues. We care about user experience and made our options really easy. ImprovedTube cares about your privacy and only modifies your view locally, offline. The extensions enables faster video playback on some devices. So together that saved tons of electricity(/co2) (through h.264 )
A few more things you can do with ImprovedTube are: Fixed playback speed, disable up-next, autoplay, change video size to fit the whole tab or specific resolution, fixed volume, auto-pause, hide any distractions, ("presentation / teacher mode") to save time, to make Youtube more fun or clean to and use it in a presentation for example ("teacher-mode"), ..., ...and much much more. Instead of reading about all of the options, you should install the extension and see for yourself what ImprovedTube can do for you. Many of our users love ImprovedTube so much they can not use YouTube without it.

What are you waiting for? ImprovedTube is free to download and use. With over 300,000 active users, a nearly perfect star rating you have nothing to lose.

ImprovedTube is made out of love for people
We were shocked, that our testing version was sent to everybody. Chrome Web Store actually got an option to test a new Version with 1,2,3% of users only - however this does not seem to work and update everybody untested...
So all it takes to confuse is one click in webstore. (this will not happen again). We learned in the last 8 years and the next 8 will be better/more perfectionist. (if you like to help testing though (rarely) please join our BETA)
