How to View Internet Explorer inside Firefox

This is an user contributed article.

I'm a devoted Firefox user like most of you. However, at work I use Internet Explorer for couple of web applications that works only on IE. Wouldn't it be nice to embed Internet Explorer inside Firefox as a tab to browse the websites that works only on IE? This is exactly what Firefox add-on IE Tab does as explained below.

This is a great tool for web developers, since you can easily see how your web page displayed in IE with just one click and then switch back to Firefox.

Update: This is Windows specific tool. See how to install IE under Linux using IEs4Linux.

Security Alert: How To Stop Firefox Clickjacking Exploit Attack

Really scary exploit attack in wild, which affects all browsers under any desktop operating systems including MS IE, Linux, Apple safari, Opera, Firefox and Adobe flash. Any website that uses CSS, flash and IFRAME (used to serve ads) can be used to attack on end users. Attacker is able to take control of the links that your browser visits. From the article:

In a nutshell, it’s when you visit a malicious website and the attacker is able to take control of the links that your browser visits. The problem affects all of the different browsers except something like lynx. The issue has nothing to do with JavaScript so turning JavaScript off in your browser will not help you. It’s a fundamental flaw with the way your browser works and cannot be fixed with a simple patch. With this exploit, once you’re on the malicious web page, the bad guy can make you click on any link, any button, or anything on the page without you even seeing it happening.

According to victims on several Web forums, the attack is coming from Adobe Flash-based advertising on legitimate sites — including Newsweek, Digg and MSNBC.com.

How do I stop Clickjacking under Firefox?

There are two solutions.

Option #1: Disable everything

Disable scripting and plugins such as flash and others for the time being under Firefox (except adblock plus or no-script plugin). I've no idea how to do this under IE or other browsers. Under Firefox clock on Tools > Add-ons > Select each plugin and disable it.

Shutdown browser. Next, remove Adobe flash from system using apt-get or from your directory. If firefox 3 installed at /opt/firefox/, change directory to /opt/firefox/plugins:
# cd /opt/firefox/plugins
Delete flash and other plugins files:
# rm *
This should work for other browsers too.

Option #2: Use Noscript To Stop Attack

Download latest version of NoScript firefox plugin. NoScript for Firefox pre-emptively blocks malicious scripts and allows JavaScript, Java and other potentially dangerous content only from sites you trust. Once installed restar firefox. Click on NoScript icon located on bottom right status bar > Select options > Click on Forbid [IFRAME] > Ok

Bonus option # 3: Use lynx

Lynx and other text based browsers are not affected by this exploit. Lynx is a free open-source, text-only Web browser. Recent version works under Mac OS X, All versions of Windows and UNIX like operating systems. You install lynx using apt-get or yum command:
# apt-get install lynx
# yum install lynx
