What features? Tabs? What other features does it have, right out of the box? You may not have crashes but the list of FF users from our 30 forums that have had issues is ponderously long. I rarely ever hear from Opera or IE users.

I wrote a program for in house use on the job I had before this one. A fairly simple one, mostly to make my job easier, but they still use it there now that I'm gone. I built in error handling in the unlikely event that there was an issue with a record returned from the database.

Unfortunatley, the one potential error i DIDN'T handle was, what if the connection to the database failed. See, I didn't know they were going to change the path to the server housing the database, but still I should've provided for that possibility that the connection would fail. I didn't do such a great job on it.

That's a simple example of what I'm talking about. Most every aspect of page rendering and code interpretation should be in try/catch blocks,and trap errors.
