After updating Firefox to 2.0.0.2 yesterday, all my TabContainers have stopped functioning. Whenever a postback occurs, the entire TabContainer disappears and I get a javascript errorError: Sys.InvalidOperationException: Component 'ctl00_ContentPlaceHolder1_TabSet1' was not found.
Tested in IE 7 and they continue to work, and they were working fine until updating to the new version of Firefox.
This has become a problem for me - I had to remove all update panels that I had associated with my TabContainer control. Here is a little more info on the problem:
Repro:
In FireFox 2.0.0.2 only...
See below for .aspx file to test against. In short, put a TabContainer inside of an update panel, cause a post back to occur.
Expected:
Postback should occur normally, tab container is updated inline.
Actual:
Javascript exception is thrown, Error.invalidOperation() , in file (I believe) MicrosoftAjax.js, function function Sys$Component$_setReferences(component, references) .
Notes:
* http://www.mozilla.com/en-US/firefox/2.0.0.2/releasenotes/
* Stepping through the code actually seems fine - but I've not done much debugging in this particular portion of Ajax.
<%-- Sample, broken TabContainer inside of Update Panel --%>
<%@. Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %><html><body><form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="Server" /> <asp:UpdatePanel runat="server" ID="updatePanelForTestControl" UpdateMode="Conditional"> <ContentTemplate> <ajaxToolkit:TabContainer runat="server" ID="Tabs" ActiveTabIndex="1"> <ajaxToolkit:TabPanel runat="Server" ID="Panel1" HeaderText="Tab 01"> <ContentTemplate> First tab panel </ContentTemplate> </ajaxToolkit:TabPanel> <ajaxToolkit:TabPanel runat="Server" ID="Panel2" HeaderText="Tab 02" > <ContentTemplate> Second tab panel <asp:Button ID="Button1" runat="Server" Text="Post Back" /> </ContentTemplate> </ajaxToolkit:TabPanel> </ajaxToolkit:TabContainer> </ContentTemplate> </asp:UpdatePanel></form></body></html>
I'm not sure who owns the responsibility here - if it's an update panel issue, or a TabContainer issue. As such, I posted an "issue" on the AjaxControlToolkit forums:

Investigation is ongoing. What appears to be the case is that the Firefox 2.0.0.2 update changed the ordering of two browser events UpdatePanel uses in such a way as to break certain aspects of ASP.NET AJAX. Microsoft folks are looking into the issue now and should update this thread (or maybe post a new, sticky one) once they know more.
that is casewe are working with the firefox team actively to figure out the best approach to address this issue and we will update this thread as soon as we know more about it.
Just to expand on this, my customers have told me of problems with Telerik RadAJAX and MagicAJAX when FireFox 2.0.0.2 was installed.
Telerik has already published a fix:http://www.telerik.com/community/forums/thread/b311D-tccek.aspx
I have yet to validate the MagicAJAX problem.
From my perspective as a custom controls developer, it sounds like FireFox did a bad thing because they've broken a lot of AJAX-based sites.
FYI, the ASP.NET AJAX team will be tracking this issue here:http://forums.asp.net/thread/1600941.aspx
Please check there for up-to-date information.
It seems that in FireFox 2.0.0.2 dynamically loaded javascript files (much needed by all AJAX frameworks) are handled in a completely different fashion, whici as far as I can see is causing major problems fror all AJAX frameworks. The guys from telerik are ready with the update and created a hotfix (Q4 SP2) - so if you are using telerik r.a.d.ajax - just upgrade. I'm sure Microsoft guys will respond as quickly as possible as well (and I am well aware that for company like Microsoft and for product like ASP.NET AJAX this will take some time).
Here is the bug I believe is related (since I've seen most AJAX libraries use the innerHTML approach for dynamically loading javascript under the hood).
