An anonymous reader writes: Do you use YouTube with Adblock Plus? Some users have been getting the following message instead of ads: "An error occurred. Please try again later." The error message is only shown for the duration of the ad, meaning Adblock Plus is still technically getting the job done. But adblocking extensions typically block ads as well as remove them: For banner ads that means gaining back screen real estate on the webpage while for videos that means the content starts playing right away.
