422746 - Any tab with a Java applet running, even on a different tab, stops click events from reaching Flash content

Status: RESOLVED DUPLICATE of bug 420527

(Core Graveyard :: Plug-ins, defect)

Description

[John Flynn]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b4) Gecko/2008030317 Firefox/3.0b4
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b4) Gecko/2008030317 Firefox/3.0b4

If you have several tabs open and there is a running Java applet on one tab, clicks on flash applications on other tabs do not make it to flash. You can get around this by right clicking on the flash applet, then clicking, but this is obviously broken.

I have only seen this on Macintosh OS X Leopard 10.5.2 so far and have not tried it on any other system. Running Firefox 3 beta 4.

Reproducible: Always

Steps to Reproduce:
1.Open a web page with a java applet in one tab.
2.Open a web page with Flash in another (YouTube for instance)
3.Note clicks on Flash content not working.
Actual Results:  
Clicks are lost.

Expected Results:  
Clicks should get through.

I've confirmed this (on OS X 10.5.2), but only on the trunk (not in
Firefox 2.0.0.12 or Camino 1.5.5), and only as of the
firefox-2007-03-27-04-trunk nightly.

This regression range makes it very likely that the patch for bug
344427 ("Implement CoreGraphics NPAPI Drawing Model") is what caused
(or triggered) the problem.

(Later I'll also test on OS X 10.4.11.)

Here are the specific steps I used to reproduce:

1) Start the browser and visit the following URL: 

   http://java.sun.com/applets/jdk/1.4/demo/applets/ArcTest/example1.html

2) Open a new tab and in it visit the following URL:

   https://bugzilla.mozilla.org/attachment.cgi?id=229874

   Notice that, though you can enter text in the first field, you
   can't click on the button at the bottom.

3) Close the first tab (the one containing the Java applet) and	reload
   the Flash "movie" in the other tab.

   Notice that you can now click on the button at the bottom.

How is this different from bug 420527 (QuickTime movie involved instead of Java applet) ?

Yes, this bug does seem to be a dup of bug 420527.
