When I first switched to Firefox, one of the things that made me crazy was trying to figure out why my own company home page didn’t render exactly as it did in IE. I tried everything and just couldn’t resolve some single pixel CSS issues. I decided that rasther than worry about the details, I would fix it in a future release of my site. Most users probably see it in IE, and the Firefox users haven’t said anything to me in yet, so maybe they thought it was intentional.
As I write this from Deer Park Alpha 2, I am pleased to report the problem has been resolved. Unfortunately for me, this bit of fourtune comes a bit late as I am about to release a new site where the issue was “worked out”. Which is to say, I used a whole different navigation system which doesn’t suffer from the same issue.
In case you’re wondering, alpha software is in theory even less stable than beta software. It is full of bugs and finding them is part of the purpose of using alpha software. Plus, some of us just like new toys. The weak of heart and those who don’t back up their data shouldn’t be trying alpha software.
Note: The Deer Park build you are using is NOT A FINAL OR PRE-RELEASE VERSION of Firefox, it has been made available for testing purposes only, with no end-user support. If that sounds scary, you’d probably be better off with the latest version of Firefox that you can download here.
Generally speaking, beta software is almost ready for production, and should have relatively few bugs left to find. Unfortunately the specific meaning of beta varies widely from company to company so when you use this stuff you should really look into what it means for the individual company or group who is distributing the software.
