Internet Explorer has an enormous amount of security flaws. Surfing the web in IE can open your computer up to viruses, adware, spyware, and other malicious programs. While you may not be 100% safe using any browser, Internet Explorer is the only browser that uses ActiveX and Active Scripting, two technologies proven to be extremely vulnerable to viruses. Due to Internet Explorer’s integration into windows, viruses affecting IE can effectively control your entire computer. Along the same lines, if IE crashes, it will often crash the entire Windows operating system.
As a web designer, I frequently encourage people to use a browser such as Firefox because it supports web standards. Web standards are agreed-upon methods for designing and coding websites. They ensure the greatest compatibility for all users. Firefox, Safari, Chrome, and Opera are browsers that quickly adopt support for new standards as they emerge. In contrast, Internet Explorer is almost always the last to conform to standards and still lacks the majority of new features that have emerged. For web designers, this means that once we have created a website using good clean code, we then have to add hacks, fixes, and custom pieces to accommodate for IE.
With IE, what you see is what you get. While Firefox, Opera and Chrome all allow for incredible extensions, IE users are stuck with limited out-of-the-box functionality. With the power of extensions, users can customize their browser to add functionality and speed up their workflow. Extensible browsers can add features with ease, such as themes, re-organized layouts, PDF managers, multimedia plugins, e-mail integration, smart bookmarks, or additional security features.
If you want a richer, more secure browsing experience, ditch IE and grab one of these modern browsers:
