Ever run into a video that's blocked because you aren't in a supported region? It's annoying, but ProxMate is a simple extension for Chrome and Firefox that unblocks region-specific content from YouTube, Hulu and Grooveshark.
ProxMate will route your traffic through a supported proxy server regardless of what country you're in. Currently it only works with the above mentioned services, but ProxMate also lets you set up your own proxy servers to automatically get around any country-specific blocks you might run into. The nice thing about ProxMate is that you can quickly enable or disable it straight from the toolbar so it doesn't slow down load times when it isn't needed.
