319756 - Firefox Central should have a download firefox link if user isn't running latest version

Status: RESOLVED FIXED

(www.mozilla.org :: General, defect)

Description

[Mike Beltzner [:beltzner, not reading bugmail]]

Firefox Central (now "Welcome to Firefox") is both:
  1. the page that you hit when you smack the throbber
  2. the page that you hit when you first load an en-US Firefox build

For people who are running <1.5 that smack the throbber (or start after installing an earlier version) we should include a download link that says "Upgrade to the latest version!" using the standard green-button style that's across all the moz.com sites.

I'm guessing that this can be done with a little UA-sniffing. This should yeild the following experience:

firefox 1.5 user
 - sees "Welcome to Firefox!"

existing firefox <1.5 user
 - sees "Welcome to Firefox!" and "Upgrade to the latest version!"

Is there a snippet of JavaScript we can re-use that does the 1.5 vs. pre-1.5 detection that we can use, or should we write something ourselves?

var m = navigator.userAgent.match(/Firefox\/([0-9]*\.[0-9]*)/)
if (m && parseFloat(m[1]) < 1.5) {
  // ...
}

actually, slightly better would be

var m = navigator.userAgent.match(/Firefox\/([0-9]+\.[0-9]+)/)
if (m && parseFloat(m[1]) < 1.5) {
  // ...
}

Is this still wanted?
If so, where do you want this download link on the new central?

Our first run pages do inform visitors of newer versions now.
