Description

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:20.0) Gecko/20130107 Firefox/20.0
Build ID: 20130107030932

Steps to reproduce:

1. When using Google chrome type http://www.mozilla.org/en-US/firefox/new/ in the address bar and press Enter
2. Open up the developer tools and run a webpage performance audit under the Audits tab.


Actual results:

~27% (17KB) of the CSS served to the user it not used.


Expected results:

Because of the high traffic on this page, a more optimized version of the CSS should be sent to the user. This will improve performance for the user and save bandwidth for mozilla.

The /firefox/new/ page will go away in the next few weeks once new-b replaces it.

On /new-b/ there is 16.47KB (25%) of unused CSS. Not a big deal on regular sites but I think this page is special. I have a strong feeling that a typical user for this page just visits this specific page (hit and run) and does not visit any other pages on mozilla.org. (just speculating though)

+1 to that. On pages where speed and conversions are the number one priority, anything unused should be minimized or removed. We should continuously improve important pages like the new-b page and others. Let's keep this open to evaluate new-b and specifically what can be removed.
Cmore:  what do you want to do with this one?  Close?  Create a task on the mozilla.org kanbanery board backlog?

:icaaq: Can you do a pull request to simply the CSS and remove the unused elements?

jbertsch: I think this is worthwhile because the smaller and quicker the page, the better for conversions.
