Works fine with WYZO 3.5.6.1 Rated 4 out of 5 stars

For someone who needs/wants the ability to use a proxy server instantly, on a site-specific basis, Hide My Ass (on Wyzo) works beautifully.

IF you're looking for a more robust solution - I'd say, use TOR, but, HMA allows through it's pre-configured options, any user to instantly anonymously view a website - either by adding 'hma_' before the address, or, by simply hitting the 'h' icon on the search bar.

This review is for a previous version of the add-on (1.2.6.1-signed).
