personas?  share|improve this question add comment  2 Answers

Install the Personas Plus extension from
http://www.getpersonas.com/en-US. After you install and restart
Firefox, go to addons (tools > addons), click preferences for
the Personas Plus addon, and uncheck "show preview when
selecting from menu".  share|improve this answer add comment  It
is a piece of Javascript running that is annoying you so the
easiest way to disable it is to install the NoScript add-on.
Once installed you can easily set it up to block the page in
question from running the javascript that is annoying you.
