I'm not really sure what happened.
I began but then stopped to download Flash Player when I realized that Chrome had automatically updated it so it wasn't necessary. I did update Java. I am also pretty sure that I tried relaunching the browser, resetting the parameter ram, and clearing the browsing data from the past week. Nothing worked until I paused AdBlock. I had done nothing to update AdBlock.
The affected site is one that allows you to stream tv shows, watchtv.to. Without pausing AdBlock, I just get an image of the tv program as if a DVD box, but no listings for the individual seasons or episodes. These, and the related links, appear only when AdBlock is paused.
