I was told to install this so that I could rotate videos from horizontal to vertical but there is no button to do this. If you help me I will give you a 5 star rating.
edit: please keep your promise ------- hi, you 1. click the 'Improve Youtube!' (extension icon, top right of browser), 2. 'Player' 3. 'Rotate' (you will find a new button in the youtube player) -2. Alternatively you can just Type 'Rot to enable the feature ( please understand we are hardworking volunteers and blackmailing with one star rating is not right. There should be big reason. It can frustrate us for a long time. Even with 4 stars the pressure is real.) many smiles
