Plugins are in important part of the browsing experience. That is why we could use your help testing the fix for https://bugzilla.mozilla.org/show_bug.cgi?id=525533. Here is what you need to do tomorrow when the fix will have landed:

1. Update to the latest 1.9.2 Mac nightly build or download the latest Mac 1.9.2 nightly from http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-1.9.2/

2. Comment 5 in the above referenced bug has some suggestions of what to test - basically some of the following items would be helpful:

- Flash instances hidden by a new tab, make sure audio does not cut out
- Gmail voice chat, make sure audio works without skipping even when tab is
hidden
- YouTube, make sure videos play without skips and at the correct speed when
not hidden
- Hulu, test video speed and audio as in the suggestions above

Please report bugs you see in bugzilla.mozilla.org or ping marcia on irc.mozilla.org in 
the #qa channel if you see something that does not look right.

As always, thanks for your testing efforts.
