Dooble is a free and open source Web browser. Dooble was created to improve privacy.[2] Currently, Dooble is available for FreeBSD,[3] Linux,[3] OS X,[3] OS/2, and Windows.[3] Dooble uses Qt for its user interface and abstraction from the operating system and processor architecture. As a result, Dooble should be portable to any system that supports OpenSSL, POSIX threads, Qt, SQLite, and other libraries.[citation needed]


Dooble is designed and implemented in order to improve privacy and usability.


Version 1.26 of Dooble introduced support for addons. The TorBrowser Add-On[addon 1] based on Vidalia was added in version 1.40. The Vidalia plugin was removed in version 1.49.

The Add-On with the name InterFace[addon 2] expands the browser with social network functions like a messenger with group chat, a friend list, an e-mail client, a chess game, and a forum function like a bulletin board. InterFace is based on Qt and can be integrated as a plugin. It's based on a clone of the RetroShare Messenger. The plugin is considered deprecated.


Dooble includes a simple bookmarking system. Users may modify bookmarks via a bookmarks browser and a popup that's accessible from the location widget.

Cookie Management

Along with standard cookie management options, Dooble also provides a mechanism that automatically removes cookies. If permitted, Dooble will occasionally remove undesired HTTP cookies.[4][5]

Distributed Search Engine

Dooble partially integrates the distributed search engine YaCy.[6]

Encrypted and Authenticated Information

Most of the data that Dooble retains is stored using authenticated encryption. Dooble does not encode file associations and user settings. Dooble also provides a session-based model using temporary keys. The passphrase may be modified without the loss of data.

File Manager and FTP Browser

Included is a non-JavaScript file manager and FTP browser.[5]

Proxy Configuration

Configurable proxy settings provide reasonable flexibility.

Session Restoration

Dooble supports session restoration for authenticated sessions. If Dooble exits prematurely, the user may restore previous tabs and windows at the next authenticated session.

Third-Party Content Blocking

Some Web sites employ iFrames in order to distribute content from one or more third-party Web sites. Since this technology may raise privacy issues with some users, Dooble provides a means of blocking external content.


A security passphrase can be created for the browser. The password can be set from the Safe area of the browser settings.[7]


The first version (0.1) was released in September, 2009.[6] The current version (1.51) was released on March 1st, 2015.[1]


Dooble is also available on Nokia's N900.[8]


Dooble has been rated as the ninth of ten "top" Linux browsers by Jack Wallen.[9]
