  1. In Firefox 4, visit a site containing an embedded object such as the NVDA web site.
  2. Move to and press enter on the embedded object.
  3. Press NVDA+control+space to get out of it.
  4. Expected: Focus should be returned to the document.
  5. Actual: Nothing.

The problem is that in Firefox 4, there is no separate document window. Previously, the document window was the parent of the embedded object window, so moving up the hierarchy eventually landed in the document. Now, you land on the top level Firefox frame.

Fixed in d5b4d42, however only tested with Flash so far. Can be closed if we can get an answer on Java.

Java is a bit strange and doesn't seem to use a !GeckoPluginWindow at all. Unfortunately, this means this fix won't work for Java (and I'm not even sure we can fix it).

The good news is that I tried this with a browser embedded Adobe Reader document and it does work very nicely there.
State: closed

Note that the solution we implemented here was very much a hack. The correct solution is to get this fixed in Firefox. See MozillaBug:646360.
