I recently got actually burned by this. I was implementing the redesign for a friend’s website. I was working in Firefox, cause that’s the browser I want to support. The page seemed pixel perfect to me. Then my friend told me there was a subscription form he didn’t want at the bottom of the page. What was my suprise when I found out that there was an entire partial with an html error in it, that I missed in code, which was rendered in Chrome, but it was not rendered at all in Firefox.

I've been a Firefox user since version 2 and experienced this kind of thing early on.

Years ago I was making a GeoCities page and thought it would be a great idea to add a little picture/icon that followed the pointer around on the webpage (because that was a "cool feature" offered on the site builder at that time). I couldn't get it to work no matter which picture I tried, and I kept trying to add them many more times before eventually giving up on it.

Some time later I wanted to show off the site to a family member on their computer. I pulled up Internet Explorer (because they didn't have Firefox) and navigated to my webpage, where I was greeted by a swarm of icons following the pointer around and slowing the whole computer to a drag.

Lesson learned, test on multiple browsers because people will probably view your site in multiple browsers.
