It stopped working with Firefox&Chrome. Google/Youtube is still trying to prevent us from seeing the dislikes. It works only with Microsoft Edge. Version 3.0.0.11
@ALL: STOP GIVING ONE STAR FOR SOMETHING THE DEVELOPER IS NOT RESPONSIBLE FOR. I'M SURE THERE WILL BE AN UPDATE AND AFTER THAT GOOGLE/YOUTUBE WILL MAKE SURE IT DOESN'T WORK AGAIN. BE GRATEFUL THAT THIS ADON EXISTS!
