For what it is worth, I received a reply from to the Hulu help request. We'll see if it recognizes Adblock Latitude consistently now.
• First, please try lowering the video quality. You can do this via the gear icon in the corner of the player window.
• Clear your browser cache (
http://hulu.ly/cache ) and try a different video on our site.
• "Delete all sites" from your Flash cache here: (

• Try turning off hardware acceleration in Flash by right-clicking on our video player, selecting "Settings," opening the left-most tab and and unchecking "Enable Hardware Acceleration."
• Perform a power-cycle of your router, modem, and computer. Unplug all three from power, wait at least 3 minutes, and power back up.
• Finally, using another browser can often circumvent the problem altogether. If you haven’t tried that already, I recommend trying Google Chrome, which you can download here ( http://www.google.com/chrome ). Chrome can avoid several types of issues like this because of its built-in version of Adobe Flash and its tendency to use your computer’s processing power efficiently.
Video quality is set to auto but I did clear the Pale Moon cache (even though it is set to clear when the browser is closed) and deleted sites from the Flash cache. I see no reasoning for power cycling the router, modem and computer and replied that I have absolutely no interest in using that other browser.
