I’m not sure if this a settings problem or an HTML problem, but on a page layout I’m working on, Firefox does not render the stylesheet immediately. Meaning for maybe half a second I can see the unstyled page, then the stylesheet kicks in and it renders as I expect.
All my stylesheets are in external css files loaded in the head tag. I’m not encountering this on Flock (which is a Firefox variant) nor on Google Chrome/IE.
Any idea how to avoid it?
Firebug definitely slows down the page render time. Brutally so.
Additionally, Install yslow: http://developer.yahoo.com/yslow/ in firefox to make sure that your page is optimized to its fullest.
Show us the page! Is it valid?
You might want to search for “flash of unstyled content” or “FOUC” and see what comes up, that’s the commonly-used phrase for this phenomenon.
