HTML5 in adverts? I blocked the FLASH ones easily enough!
To think that adverts switching to HTML5 would be a GOOD thing... it's *NOT*.
they're MUCH easier to BLOCK when they use FLASH! How? DISABLE THE FLASH PLUGIN!
(we should keep advertisements in the 'flash' ghetto, for our own good)
Also 'NoScript' helps eliminate flash content. It's amazing how much FASTER a web site that does NOT load embedded video content will display, compared to the alternative...
