Firefox

So I have a confession to make… I disapprove of Internet Epxlorer.
For a long time all I used to browse the internet was IE (Internet Explorer) because I thought that was all there was. But when I discovered FF (Firefox), maybe 3 years ago, I made the switch and never looked back.
As good web developers, designers should keep both browsers in mind when creating online content. As an example of Internet Explorer’s failings I thought I’d give you glimpse of the difference between browsers. Below is an example of the Imagivation top site.
Exhibit A: viewing Internet Explorer at 1280 pixels wide
Exhibit B: viewing Firefox at 1280 pixels wide
Exhibit C: viewing Internet Explorer at 1024 pixels wide
Exhibit D: viewing Firefox at 1024 pixels wide
Every once in a while I’ll be visiting a friend’s house or at the library and I’ll have to use IE. Every time that I do I cringe inwardly and wonder how they can stand it. 
Here are just a few of the reasons to prefer FF over IE:
- More secure
- Open source
- Plethora of plugins
- Better tab management
- Uses fewer computer resources
- It’s faster (in my case, my computer runs so slow that the difference is very noticeable)
31% of internet users have seen the light and use FF, 59% remain in darkness and use IE. If you haven’t made the switch to Firefox, then I would strongly encourage you to do so. Click the button on the right to download the latest version.
