Although most of us have nothing to hide when it comes to browsing the web, it's always nice to have the option of destroying Internet traces. Distrust is a neat little plug-in for Firefox that removes any evidence of your browsing activity with just one click. Once the program is installed you simply click the Distrust button in the browser and it will return Firefox to its starting state.

The extension deletes a wide range of details, including browser cache, addresses, history and downloads. The result is that anyone who doesn't want other users of their PC to find out what they've been up to can remain secure. The extension can be set to display all the relevant details of your surfing instantly, and proves much quicker than using the Firefox Options as a means of hiding your tracks.
