Works! Rated 5 out of 5 stars

it's useful!! I need this! thank you!

I have been using this for quite sometime now to bypass any site restriction (of course you will need to find a good proxy list to use with it).
It is better than using a proxy site sometimes, because a lot of the proxy sites can't handle embedded items (like certain embedded videos), but I do not have such problem when using FoxyProxy.

This review is for a previous version of the add-on (2.16.1).
