Don't enjoy beating a dead horse, but the problem is growing worse... just in the past few weeks.
For those who use Chrome, the "Disable html5 Autoplay" extension doesn't work in most news websites.
A secondary problem is getting worse... and that is that there is a time delay that starts the "videos" a minute or so after you have begun reading an article.
For those who are using the "Mercury Reader" extension or the "IRead" extension, when the video begins to download, the website may/will "freeze", asking you if you want to "wait", or kill the page. Waiting doesn't work, so you have to kill the page. This effectively means you can't use the "reader" extensions.
This started on a few of the better know news websites, but has now extended to more, less popular sites.
The problem that I see, is that the sites don't really benefit from more ads being seen. For some of the news sites, it may be a way of forcing pay subscriptions.
not for this puppy...
