It seems like the Silverlight player in Firefox crashes on my Windows 7 machine when I try to go into full screen mode. The crash freezes the entire browser when I try to click yes on the prompt that asks for permission to run in full screen mode. We tested this on 2 machines in our office and the crash happens on both. IE and Opera run the player just fine. Any chance you can fix that (or even report it to the SL team if this is a plugin issue)?
What version of FireFox are you running? (Don't know of any issues, but it will help when I pass this along to the SL team)
I get the same thing. Running:
This is the Firefox version: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:188.8.131.52) Gecko/20100914 Firefox/3.6.10
I also have some developer add ons installed which may or may not cause a conflict.
Fiddler Hook (obviously installed with Fiddler)
I also have Java in the list of add ons and something called Default Manager
The plugin tabs shows Silverlight, Flash, Java, some MS Office 2010 plugins, Adobe Acrobat Reader, Google Update and something called WPI Detector.
i am having the same issue. Using Firefox 3.6.11, Silverlight 4
It was fine until the latest update. Probably a bug in FF rather than SL.
I'm not sure which other sites are using the new full-screen pinning feature, but I'll make a simple test player and perhaps we can see if it fails for you as well
So I noticed that the same SL player is used on http://live.visitmix.com and I have no problems there, or any other site (including my own).
@dwynne:we run that site as well, so I can tell you that it isn't the same player... not in the way that matters here. Our player is using a new SL4 feature, full-screen pinning, that the MIX site is not.
@Duncanma: I can go in and out of that player fine, but I don't get the consent dialog like I do on ch9 and that seems to be the point at which FF locks up and I have to end process.
I’m getting this here. Every time I've tried, for several weeks.
To replicate, I do the following: Open firefox, go to a channel 9 video, start the video playing, click the “fullscreen” button. “The do you want to allow the website to say in fullscreen mode” dialog comes up, but it's not resposive to clicks and that’s it – firefox has crashed.
I suspect that you my not get this if you previously managed to check the “always allow fullscreen” setting on the popup. If you haven’t, well, Silverlight crashes firefox hard. The whole FF locks up, not just the one tab, and has to be killed via task manager. I have this across the last 2 released versions of Firefox – 3.6.10 and 3.6.11. This only happens on channel nine videos.
I have windows 7 and Silverlight Version: 4.0.50917.0
It's a very annoying and quite a drastic bug, since it kills all open firefox tabs stone dead (e..g the bug report you're tying into channel 9 forums...), not just the msdn page. The workaround from Adam777 of clicking the popup in another browser works as follows:
* Launch IE (or other browser I suppose, I haven't tried) * Navigate to the video in this browser * Start the video, request fullscreen * On the confirmation popup, check "remember my answer" and then click the "Yes" button. * Restart firefox * Navigate to the video in firefox * Firefox will now fullscreen the video without using the dialog of doom.
You can then recreate the bug again by de-remembering the answer: right-clicking the silverlight video, selecting the "silverlight" menu item to bring up the "Microsoft Silverlight Configuration" dialog, go to the Permissions" tab, and remove the permission for "http://channel9.msdm.com:80 | Stay Full-screen when unfocussed"
The dialog of doom will return.
Perhaps people who cannot replicate this problem could try this?
I had the same problem with FF 3.6.12. I followed the suggestion of Adam777 and it has worked - no more popups so no more crash
The issue is not with the media player. It is with the administrative popup in Silverlight (launched when your permission is required). I have had this issue when trying to go full screen, as well as in the new Azure portal when trying to copy a key to the clipboard.
