Mac OSX WebGL Anti-aliasing Blocklisting

The following is a test plan for testing a blocklist to disable WebGL Anti-aliasing on Mac OSX 10.6 and higher (bug 809550).

How to Test

• Start Firefox with a new profile and load msaatest.html
• Change "addons.mozilla.org" to "addons-dev.allizom.org" in extensions.blocklist.url in about:config
• Force a blocklist ping by evaluating the following string in Error Console:
  • Components.classes["@mozilla.org/extensions/blocklist;1"].getService(Components.interfaces.nsITimerCallback).notify(null);
• Wait a minute and restart Firefox
• Load msaatest.html again
