I found a more efficient way of browing the internet without the fear that of forgetting to delete all the data on history, forms, downloads, cookies and cache, using the Distrust plugin for the Mozilla’s Firefox browser.

Distrust plugin works with Windows and Mac and will allow keeping all our browsing history in a single session private, because Distrust will automatically delete any new items added to your [History], [Cache], [Cookies], [Forms], [Downloads], and anything else that was stored or logged on your computer when “Distrust” was enabled.

Download the plugin here.
