There is absolutely not a single developer in the world who knows what size I like my browser, although many people think they do. To prevent resizing of FF make the following steps.

1. Open browser preferences
2. Choose “Content”
3. Choose “Advanced” on the “Enable javascript” preference
4. Untick “Move or resize existing windows”

These CSS rules remove most, if not all, browser specific styles from common HTML elements. Your page will look almost identical in all browser when using these CSS rules. Note that this is a combination of Tantek Celik’s undohtml.css and YUI ’s reset.css.
