User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20130409 Firefox/22.0 Build ID: 20130409004013 Steps to reproduce: Update aurora to v22.0a2 (first releasy day) then start an event which has a countdown on the website of a game. Having a greasemonkey script that start: <embed src (...) hidden=false autostart=true loop=false> Actual results: The song is add on the page and don't start. (Actually, flashgot plugin detect the song) Expected results: The script should have add the song and play it automatically, as in previous version of firefox. (I've just tried on the beta version: it works)
The embed tag has no "autostart" attribute -- this would be passed to the plugin, and its intended effect handled there. Do you have a URL / testcase or steps to reproduce this problem?
1) Download greasemonkey: https://addons.mozilla.org/fr/firefox/addon/greasemonkey/ 2) Restart firefox to complete download 3) Install the script: https://userscripts.org/scripts/show/139372 4) Go to http://r1.bloodwars.net/r.php? 5) Fulfil the gap to register (can choose random nick, email, character name) 6) Click on Settings on the left menu ( http://r1.bloodwars.net/?a=settings ) 7) You may see some text in polish. Tick the box of the line: "odgrywaj dźwięk po zakończonej wyprawie/ataku" which is followed by a box containing the url of a song 8) Click on Begin a Quest on the left menu ( http://r1.bloodwars.net/?a=quest ) 9) Click on the button "Depart" in the middle of the page A countdown of 5 minutes has just started. At the end of this countdown, the song does not autoplay with v22.0a2
Which plugin is used in your testcase ? Does it work if you switch media.windows-media-foundation.enabled to false in about:config ?
Firefox is using quicktime Plug-in 7.7.3 (in Aurora) to open .mp3 files. However, if I go on a page which url is a mp3 file of my ftp, I can listen to it without any problem. Does it work if you switch media.windows-media-foundation.enabled to false in about:config ? -> No Sry, should have tried nightly version before posting here. The result on nightly: it does not work either.
