We have just released Aurora 13, together with a number of improvements.

Highlights

There are a couple of things we’d like to shine some extra light on here:

SPDY on by default

The SPDY control brings responsive and scalable transport to Firefox. It allows for multiplexing and connection sharing and is SSL only. It will offer faster page loads and better scalability for SPDY-enabled web servers.

Our first implementation was in Firefox 11, but now with Firefox Aurora 13 it is on by default!

User Agent change for Mobile

The preferred way for web sites to offer content depending on the device is to use CSS Media Queries. However, there is a good amount of user agent sniffing still going on out there, so we wanted to make you aware of the change/difference between Firefox on mobile phones and on tablets, as outlined in Mobile and Tablet indicators.

For Firefox on mobile it will be:

Mozilla/5.0 (Android; Mobile; rv:13.0) Gecko/13.0 Firefox/13.0

Firefox on tablets will be:

Mozilla/5.0 (Android; Tablet; rv:13.0) Gecko/13.0 Firefox/13.0
