Great addon, although it stopped working in FF dev edition when e10s (multiprocess) was enabled, please fix it..
(UPDATE: there's already a bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1166517)

As for adware that keeps enabling itself, you can just open "about:config" and change the key "extensions.quickdrag.disableperiod" to something in the far future :) Dont forget to set "extensions.quickdrag.marketing" to false as well.
