Bug 773761 Comment 43 pointed out some possible leak when running the plugin test locally (leaks are not visible on the testboxen looks like):

TEST_PATH=suite/browser/test/browser_pluginnotification.js  pymake -C ../objdir-sm/ mochitest-browser-chrome
INFO TEST-START | Shutdown
Browser Chrome Test Summary
        Passed: 161
        Failed: 3
        Todo: 1
....
TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/suite/browser/test/browser_pluginnotification.js | leaked until shutdown [nsGlobalWindow #56 chrome://mochitests/content/browser/suite/browser/test/plugin_hidden_to_visible.html]
TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/suite/browser/test/browser_pluginnotification.js | leaked until shutdown [nsGlobalWindow #55 chrome://mochitests/content/browser/suite/browser/test/plugin_test.html]
TEST-UNEXPECTED-FAIL | chrome://mochitests/content/browser/suite/browser/test/browser_pluginnotification.js | leaked until shutdown [nsGlobalWindow #52 http://127.0.0.1:8888/browser/suite/browser/test/plugin_test.html]

This should be investigated. I suggest to investigate this after Bug 798278 and Bug 815954 have been fixed as those two bugs will change lots of code in the plugin UI.
