Firefox 3.6.9 now supports a server header which can help to prevent clickjacking. The new version also fixes 14 vulnerabilities, including the DLL vulnerability in the Windows version

A popular Firefox add-on designed to block scripts and plug-ins has been updated to stymie the new "clickjacking" class of attacks, the extension's developer said today.

In view of mass defacements of hundreds of thousand of web pages - with the intent to misuse them to launch drive-by download attacks - security researchers from ETH Zurich, Google, and IBM Internet Security Systems were interested in looking at the other side of the attack: the web browser.

Companies that have used Asynchronous JavaScript and XML to jazz up corporate Web sites may be dangerously vulnerable to a variety of Web-based threats, warned researchers at the Black Hat USA conference in Las Vegas this month. Billy Hoffman of SPI Dynamics said at the conference that many corporate Web developers are not paying attention to fundamental Ajax security issues.

When it comes to security, Firefox is the best browser. Not only because of the way that browser is built and how fast all bugs were fixed in it, but also because of its add-ons. Security add-ons are very effective to detect viruses before download, stop any sort of malicious scripts that could be injected to your computer. It also advice you which site you should avoid in order to be away from any bad cookies that could come from it.

Browser security seems to be a big issue this week. First we had the IE patch drama, then comes a dust-up over whether Firefox is fit for enterprise use. The Mozilla browser topped enterprise app whitelister Bit9's list of popular apps with security vulnerabilities. Why? One major reason was because Firefox typically relies on the end-user to allow updates and new patches.

Google has released version 5.0.375.125 of Chrome, a security update that addresses three "high" risk vulnerabilities in its WebKit-based browser

Ensuring browsing safety is one of the major concerns of equally users and browser developers these days. And it’s understandable because let’s face it - a lot of people practically live online. We buy and sell stuff online, we do online banking, we socialize online, and we even get online degrees. With all that going on it’s a must to protect yourself.

Security researchers warn that a new drive-by download attack is capable of infecting Windows, Mac OS X and Linux systems with a new variant of the notorious Koobface worm.
