It hides your IP to allow you to view videos that can't be accessed in Canada (or wherever you live). Is installing this safe? legal? I don't know much about IPs and proxys and such, but it seems like this would 'open' your computer in a way. (But I also really want to view some American-only videos).
This will work for any site. It is an anonymous proxy server so it assigns you a random IP address, that won't necessarily be from the US. That means, just because you use it, you aren't guaranteed to be able to access US only sites. However, more often than not, you will get US addresses. I've never tried the Firefox plugin, but I have used the executable version quite often.
Just installed it with FireFox; seems to function. However, it does not work with any other browser, as the program (excluding the .xpi file for FireFox only) is Windows only.
If you know what proxy address and port it uses, you can use it on any browser (any that let you plugin proxy information under connection).
If you google free proxy server, you'll see plenty, but most are blacklisted by sites that check for region, or are transparent (meaning even though you're behind a proxy a site could generally see which region you come from).
Yet its no where to be found on the site, as I was trying to find a stipulation that they are allowed to use your browsing habits in marketing research and what not. Basically your privacy may be secured from the sites you visit, but not their affiliates.
