Looking to fake your browser user agent? This add-on is contributing the javascript part missing in other user-agent related add-ons.

THE BIGGEST PROBLEM:

Any website where you enable javascript can see right through your fake because this add-on does not cover the navigator.oscpu part of the user agent.

So whatever OS you set in your user agent, the navigator.oscpu call will still detect your real OS (unless of course you change it manually in about:config).

And there you are... easier to identify than people with no fake at all.

I suggest the developer fix this pretty fast.

This review is for a previous version of the add-on (1.1).
