What is Dooble?
Dooble, sometimes referred to as Doodle, is a unique free and open-source Web browsing program developed by the German firm KompoZer. Dooble was designed to enhance privacy by removing unnecessary information from your screen. Dooble, like many other browsers, uses the Gecko rendering engine, an embedded script language, to operate rather than a browser requiring special hardware.
Unlike many other browsers, Dooble does not use a Portable Document Format (PDF) viewer. Instead Dooble utilizes a feature known as DBus which allows you to access documents on another system. Dooble has the ability to read and write many different types of files, such as HTML, Portable Document Format (PDF), TIFF, and many other file formats common with office software such as Microsoft Word, Excel, and PowerPoint. This means that while Dooble may not be able to open and view some common file formats like the PDF or JPEG, it is still possible for Dooble to read and be able to save them in these formats. To help conserve power, Dooble automatically decides which types of files it should display based on what it knows the user has stored in his or her computer's registry.
Dooble also has the ability to set up a password for the user. In order to do this, Dooble displays a security passphrase whenever the browser is started. By using a passphrase, a user can make Dooble restrictions and choices known to only those whom Dooble allows to see the security passphrase. This ability to set up security restrictions on Dooble sets it apart from many other browsers in that its security settings are entirely up to the user.
