There’s a big difference between a site that doesn’t work/look right in FireFox and one that actively disables the use of FireFox. I had that happen with McAfee. I recieved an email stating that my virus protection was about to expire. I followed a link in the email to purchase a renewal and got a message that I couldn’t use FF. I was frakking pissed. This wasn’t some complex AJAX site. It was a simple click and purchase. I went ahead and used IE to make the renewal after bugging customer support for a few weeks. In the end it was just to much effort to switch virus protection apps vs the simplicity of renewing but I know that I will NEVER put McAfee on another PC.

The parable of this post: Disable FireFox at your own peril.

I checked my site stats and about 90% of my visitors use FireFox. This is my third month writing this blog and I’m getting roughly 1000 unique visitors a month.
