I am currently trying to set up firefox to be locked down (using lockPref) so no changes can be made to the important stuff like the proxy and downloads. I have managed to do this with no problems...however I can't seem to disable the downloading of extensions and the installation of them.<br />
<br />
The mozilla support site mentioned xpinstall.enabled in the about:config but in version 3.6 this is not there.... <br />
Any ideas on how to disable the installation of extensions in firefox 3.x?<br />
<br />
Thank you

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
