I also tried it with µBlock v0.8.9.3.\r\n\r\nTo reproduce:\r\n- Go on http://www.younow.com/explore/tag/dance and choose a channel\r\n- Now there will be a short intro video with the younow logo:\r\nhttp://cdn2.younow.com/angularjsapp/src/assets/animations/intro-video.mp4\r\n- After that, the stream loads. (Not important, the issue is about the intro-video)\r\n- Now add the intro-video.mp4 url to the filter and reload the page\r\n- The intro-video plays again - it was not blocked.\r\n\r\n-----\r\na) The video seems to be loaded via a < video> tag in http://cdn2.younow.com/angularjsapp/build/younow.js?ver=3.201 (search for .mp4)\r\nb) Using the traffic logger from your addon: the video does not show up\r\nc) Using the traffic logger from firefox built-in devtools: the video does not show up (firefox bug?)\r\ne) Using ABP and showing the hideable elements: the video _does_ show up\r\nf) Adding the video url to the ABP filter gets the video blocked"},"comment":{"url":"https://api.github.com/repos/gorhill/uBlock/issues/comments/77661620","html_url":"https://github.com/gorhill/uBlock/issues/955#issuecomment-77661620","issue_url":"https://api.github.com/repos/gorhill/uBlock/issues/955","id":77661620,"user":{"login":"chrisaljoudi","id":2351359,"avatar_url":"https://avatars.githubusercontent.com/u/2351359?v=3","gravatar_id":"","url":"https://api.github.com/users/chrisaljoudi","html_url":"https://github.com/chrisaljoudi","followers_url":"https://api.github.com/users/chrisaljoudi/followers","following_url":"https://api.github.com/users/chrisaljoudi/following{/other_user}","gists_url":"https://api.github.com/users/chrisaljoudi/gists{/gist_id}","starred_url":"https://api.github.com/users/chrisaljoudi/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/chrisaljoudi/subscriptions","organizations_url":"https://api.github.com/users/chrisaljoudi/orgs","repos_url":"https://api.github.com/users/chrisaljoudi/repos","events_url":"https://api.github.com/users/chrisaljoudi/events{/privacy}","received_events_url":"https://api.github.com/users/chrisaljoudi/received_events","type":"User","site_admin":false},"created_at":"2015-03-07T00:33:25Z","updated_at":"2015-03-07T00:33:25Z","body":"@gorhill by the way, this is some info about the `video` element from the Firefox console:\r\n\r\n![info](http://d.pr/i/1i9qq+)\r\n\r\nThis tells me Firefox is indeed using that as a `src`, but for some reason it doesn't seem to show up in Firefox's network request logger.
