this plugin only works in Chrome. it's a great idea - one step ahead of the fb dev team. but I'd avoid using Chrome for any other purpose... it's owned by a company under the power of US courts which could, at any time, order it to turn over all the data it collected about you - all the sites ever visted, as well as every username and password - and use it to ... well, I don't want to think about it!
When I hit F5 as instructed in the video, the extension doesn't seem to activate. It says it is enabled but I do not get the new addition to the menu as noted. Any suggestion as to what I might be doing wrong?
