User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)

When I open/close a new tab, I no longer get called with setwindow through the NPAPI. I do however still get the call for resizing and such.

Reproducible: Always

Steps to Reproduce:
Add some logging to what ever you have handle the setwindow call from NPPluginFuncs and see that SetWindow is not called for the open and close of tabs.
Actual Results:  
SetWindow is not called on tab open and close.

Expected Results:  
SetWindow should be called as it was in previous version of Firefox unless a new undocumented way to handle tab changes is out there.

Maybe someone at https://lists.mozilla.org/listinfo/dev-tech-plugins can confirm or explain the change.

Joey - is this still a problem?

Yeah, I still have the problem. I'm guessing there may have been a change with Firefox or the way their tabs are handled or something, because I'm 100% positive that I did formerly get called with SetWindow when tab create/deletes occurred. I don't have a sample plugin. Is there one somewhere that I can grab to help verify this with, preferably a newer Visual Studio project to avoid any discrete differences?

Please update if you are able to still reproduce with the latest nightly build  ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/

Aravind,

This is no longer a problem. A few versions ago Firefox changed the way that tabs work. Now the tab bar is always under the navigation bar and it no longer shows or hides depending on whether or not there are multiple pages/tabs.
