New to Firefox’s nightly builds is the about:permission page, which allows users to customize their privacy. Similar to the about:config, about:permissions will allow the end user to set their browser to the level of privacy that they’re comfortable with on a per site basis.

Type about:permissions into the address bar and you’re presented with a dashboard that lets you configure password retention, geolocation, cookies, pop-ups, and offline storage access on a per-site basis.

If you’ve previously set passwords for a particular site, about:permissions will allow you to view and remove them. You can also manage and delete cookies that site has stored on your system or forget a site completely, wiping any trace of it from Firefox’s memory.

the addition of a centralized dashboard which allows users to maintain control over site permissions and data is a logical next step in the evolution of Firefox. It’s a major convenience, and one which is sure to be welcomed by those who consider privacy to be a serious concern when browsing the web

While this is a nice move by Mozilla, it’s still only in the nightly builds and needs some more tweaking before it’s pushed out to users. Then, the users have to know to check about:permissions as there isn’t currently an option in the tools or options menu.
