Lately, there have been video advertisements on this site that will automatically play with sound that are obnoxious and distracting. I would like to prevent these. The webmaster for the site claims that they do not allow these ads and yet, I get them. He says they cannot replicate the issue and suspect its a problem with my settings. I do not know if the same thing happens with advertisements on other sites or not.
On a related note, is there a way to prevent "roll over" ads from playing?
Re: How can I prevent video ads from automatically playing?
hello, one way would be to set all plugin content (like flash which is likely used for those ads) to click-to-play, which means it will only be active once you explicitly enable it on each site. therefore you'd have to enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named plugins.click_to_play. double-click it and change its value to true.
