Supervisor: Ittay Eyal
Introduction
 Many workstations, one user.
 Use the same profile.
 How can we access it!?
Project Goals
 Firefox extension.
 Backup profile.
 DHT database.
 One User – a Unified workstation.
Requirements
 Imbued to Firefox
 Transparent to the user
 Configurable
 Reliable
 User Friendly
Theoretical background
 Firefox web brwoser
 Xul
 Firefox profile
 Febe
 DHT
Extension Modules
The extension will be built from three individual
modules:
1. Firefox extension.
2. Distributed Hash Table (DHT).
3. Communication.

Extension Modules (DHT)
 What is a Distributed Hash Table(DHT)?
Node a
Node d
continuum
Node c
Node b
Extension Modules (DHT)
 The chord implementation
 OpenChord as a DHT
 Problems & Adjustments
 Serialization.
 Communication.
 Transparency
Extension Modules (Firefox)
FIREFOX:
 What is a Firefox extension?
 Extension supported features.
 Extension modules:
 Main extension module
 Profiler
 DHT connection
Extension Modules (GUI)
GUI :
 User interface in Firefox.
 Minimal User Interface in TK
Profile Definition
The profile saved in the DHT can contain:
 Bookmarks.
 History.
 Passwords + key
 Open sessions.
 Extensions (might be added later).
