There are other sites that auto-play videos with annoying sound enabled. But the most common occurrence is probably ESPN web pages (e.g. NFL scores) during certain times of the day. I am able to disable this by disabling sound for the first ESPN site I encounter when using Google Chrome. Could you please tell me if Firefox (which I've used for years) has a similar setting to disable sound for videos that auto-play when you visit the site? Environment: Laptop running Windows 10 TIA Michael T.
