When I browse youtube I normally open videos in a new tab by right clicking on the thumbnail and selecting open in new tab - Menu is displayed with options specific to the LINK i just right-clicked on. i.e. "open link in new tab" , "open in new window" , "bookmark link", etc. Now, when I right click on a youtube video thumbnail, a different menu appears, with options relating to the PAGE (itself)- i.e. "save page as..." , "save page to pocket", arrows to go to previous/next page, etc. I tried to troubleshoot in safe mode but it's the same problem. This is on both my PC and Mac. What could the problem be? Appreciate your help! Michael
