This is interesting. Silverlight installation is working on my IE7 I get the "Get Silverlight" image in Firefox. I uninstalled and reinstalled Silverlight but no change. I also installed the Silverlight Alpha Refresh. I am also on Vista Ultimate.
Any ideas why Silverlight would not work on my Firefox?
10-27-2007 5:24 PM |
Never mind. The issue was due to an add-on Firefox. It works now!

I'm interested in which add-on was causing this behavior, since I have the same problem.

It was this add-on:

Yes, I've even rebooted. Flash, Acrobat Reader etc. plugins all work fine in FF. The Silverlight "Get it here" icon appears on pages with Silverlight content. I can always fire up IE7 to view the handfull of training videos done in Silverlight but its annoying. Fortunately most of them are presented in Flash (ASP.NET, LINQ etc.).
Thanks..

Is it possible that Silverlight is disabled? You should be able to check at about:plugins.
03-03-2008 2:58 PM |
Are you running Firefox 3?
03-03-2008 3:07 PM |
about:plugins shows Silverlight enabled:
Yes, I am running FF 3 Beta 3 soon to be Beta 4! FF3 performance and memory management is vastly improved over FF2.
03-03-2008 3:48 PM |
I'm sorry to say that the released version of Silverlight.js doesn't currently work with Firefox 3, they've done a breaking change in how they interpret object tags I believe.
03-03-2008 4:08 PM |
I expected it was something like that. Seems pages displaying Flash are using either :
<script language="javascript"> if (AC_FL_RunContent == 0) { alert("This page requires AC_RunActiveContent.js."); } else { AC_FL_RunContent( 'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0',
...
or:
<script type="text/javascript"> var so = new SWFObject("movie.swf", "mymovie", "400", "200", "8", "#336699"); so.write("flashcontent");</script>
so object is not involved. Too bad, seems all of Joe Stenger's videos have been converted to Silverlight :(

I'm having this problem and have Firefox 2.0.0.14 installed. Until Microsoft resolves this I can't justify spreading the word about Silverlight or share links. The experience has to be for all browser on all platforms to have a winner and not supporting Firefox is a loose situation. :(

I agree fully. Microsoft said they were serious about Silverlight. Now it appears they can't be bothered. We have some Silverlight content on our web site, but if they don't fix the Firefox 3 problem (which is now a release candidate) very soon, it will come off and may not ever go back.

OS, Vista Home. I installed Silverlight plugin for Firefox to be able to watch Olympics content at NBC. When I restarted My browser all of my bookmarks and bookmarks toolbar had vanished. All of the navigation buttons were grayed out. My browser did not open to my home page, or any page. I typed in a URL, but still the navigation buttons were grayed. Silverlight had essentially removed all useful function from Firefox. I disabled the Silverlight plugin, but that had no effect. I was able to get bookmarks back and restore all the functions to Firefox by running System Restore. That did not get rid of Silverlight, but I disabled it again.

Linux support for Silverlight is being provided through the Moonlight project.

But they said, that MICROSOFT Silverlight is crossplatfrom :) There is no any word about Moonlight. So, Microsoft Silverlight is not crossplatfrom.
Yes, I understand, that we should wait for RTW............

It is a Firefox problem not Silverlight problem. It is mandatory to insert style="height:xx" in the div tag in order to view it in Firefox.
I had my Silverlight object inside an ajax UpdatePanel, and this control is rendered inside a simple DIV, so Firefox didn't visualize it. I had to use a custom UpdatePanel and now it's all full working.
11-03-2008 7:05 AM |
We all know this. But we don't have to modify our application for FireFox to work. They'll fix it.
11-03-2008 9:22 AM |
my previous post is just to say that is not a Silverlight problem
11-11-2008 12:20 PM |
When should we expect it to works in FireFox. We don't even know if someone is working on the problemThere's not supose to have a place where KNOWN BUGS and PROGRESS are reported on a certain blog somewhere in the thousands and thousands of blogs out there ?

The problem seems to be with web pages that were created with earlier releases of silverlight.js and/or Silverlight.supportedUserAgent.js do not recognize Firefox 3. Also, some that get past that hurdle have the percentage height problem mentioned above. Unfortunately, it looks like the web pages will have to be fixed, rather than Silverlight or Firefox. It would help if MS contacted all those developers whose sites are showcased here.

Don't use '100%' - use something like '800px' for the height
Once I used 800px instead of 100% my Silverlight ran fine

You can try downgrade Firefox to the oldest version or use other programm

dimon2009:You can try downgrade Firefox to the oldest version or use other programm
This can be funny for your customers =-\
Just imagine some bunner on your site with text like "Please downgrade your Firefox browser if you want to use our site".

Do we had an update cause my SilverLight application is working nicely in Firefox now
02-26-2009 3:08 AM |
this is really weird stuff... Firefox isn't asking any longer for a plug-in, though is still doesn't work. Firebug is giving me an error: "Sys.InvalidOperationException: ImageError error #4001 in control 'SilverlightApp': AG_E_NETWORK_ERROR"
I have no clue what image could be wrong, since everything is working fine in IE & Google Chrome
02-26-2009 3:36 AM |
Talking about weird stuff.... The error messages are really worthless!!! I just found the bug, it was simply a typo in my aspx file:

I'm running Firefox 3.5.2 (Silverlight 2.0.40115.0), IE8 (Silverlight 2.0.40115.0), and Safari 4.0.2 (Silverlight 2.0.40115.0) on XP Pro SP3. My Silverlight 2 application running in the Silverlight 2 runtime works great in all 3 browsers.
Reading all these posts makes me not want to upgrade to Silverlight 3. Anybody else running a Silverlight 3 application in all the latest browsers with no problems?
08-20-2009 12:27 PM |
I had some trouble too with Firefox until today... It was a stupid css fault, giving a ID element a class declaration ( . instead of # ). And now my SL3 app works just fine with the latest versions of IE7/IE8, Firefox, Safari, Chrome.

Thanks Dražen. The forum posts are of course mostly about people having problems, asking for help in solving them. Unfortunately, I'm having a hard time finding positive feedback. Your quick reply is appreciated!

hi Djanjicek
Even i removed the css file from application, then also my silverlight application is not opening in Mozila firefox, Even in cloud application i have silverlight control, that cloud application with silverlight is also not opening in mozila.
see this link
http://silverlight.net/forums/t/119181.aspx . which i already put this issue. can one tell me reason?
in this post someone told that setting the height to 600px is bad habit, set to 100% is good, (ya i know that because of screen resolution )
but in my post i have mention it , that silverlight app is displaying 1/3 of page in IE8 because of 100% but when i set to 600 its working fine, can any one tell me the reason
Thanks in advance.

I've struggled with the same problem for the last days, and finally found out that Firefox sometimes won't run Silverlight when it is hosted in an .aspx file.If I put the Silverlight app in a regular .html file it works fine...[EDIT]If you can put the Silverlight code "<object..." outside the form-tag, it should work fine in .aspx file as well.
09-16-2009 4:43 AM |
Can you post your aspx page? And if an external css file is used please post that one as well
09-16-2009 5:41 AM |
Thanks for replay ,
but i need it aspx page, not in html. because in my application am applying silverlight control inside the master page
Is there any other solution?
Here am giving the aspx page,
This is my Masterpage:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" MasterPageFile="~/General.master" Inherits="AzureToolService_WebRole._Default" %> <asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server"><%-- <form runat="server" style="height:auto">--%><div id="silverlightControlHost"> <object data="data:application/x-silverlight-3" type="application/x-silverlight-2" height="670" width="100%"> <param name="source" value=" ClientBin/TCOCalculator.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40624.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object> <iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe> </div> <%-- </form>--%></asp:Content>

I use IE Tab when I see the Silverlight error. Works like a charm (keeps me in FF but uses IE engine to show the page). http://ietab.mozdev.org/
09-22-2009 2:45 AM |
But that's nothing you want to tell your customers to do. I had some troubles myself, and I got it working. So I guess others can do as well
09-22-2009 4:07 AM |
can you tell me exact solution for this, because my client is excepting output in all the browsers .
10-07-2009 8:12 AM |
Hi Everyone
finally i got the solutionits very simple , i missed the comma in the object code,<div id="silverlightControlHost"> <object data="data:application/x-silverlight-3," type="application/x-silverlight-2" height="670" width="100%"> <param name="source" value=" ClientBin/TCOCalculator.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40624.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object> <iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe> </div> Now its working
10-07-2009 12:15 PM |
as a minute detail, the data type is still "data:application/x-silverlight-2,". It's only used to differentiate between Silverlight 1 (unmanaged Silverlight) vs. later versions (managed Silverlight).
