Dooble is a free and open-source web browser that aims to provide users with improved privacy and security when browsing on the internet. It is supported in the three major operating systems: Linux, Mac, and Windows. Amongst mobile devices, Dooble is also available for Nokia's N900.
Private and Free
Dooble's main feature is that it is an incognito browser by default which means it doesn't save or track any data as you browse. Users must manually allow websites to save data on their devices. Taking this feature further, Dooble is equipped with a powerful Cookie Manager where users can browse the cookies that have been installed during the session. This will allow them to view and analyze the data that are being tracked by websites.
A minor point against Dooble, however, is that there is very limited add-on support. If you are expecting the same level of customization that you can afford with Firefox or Chrome then you will be very disappointed.
Desktop In a Browser
One unique feature of Dooble is that you can access files within the browser. That said, the functions of this in-browser file manager is very limited.
Fast and Secure
Due to the lack of saved data, Dooble can perform incredibly fast. However, it doesn't offer any new features that can really compete against the established browsers, and the limited add-on support can be a bit frustrating. That said, it's still worth checking out if you want a more private browser with speedy loading and a built-in file manager.
