Firefox 15 Release Notes

Dear all,

I'm glad to announce that Firefox 15 is now available. The main change 
in the MathML layout engine is the ability to use downloadable fonts for 
stretchy mathematical operators. In particular, the MathML fonts add-on 
( is now 
fully compatible with Gecko 15. Moreover, authors can use @font-face 
rules to specify fallback mathematical fonts for users that do not have 
them installed.

Here are some notes for the release, aurora and beta channels:

* Firefox 15:
   - Mathematical operators can now use downloadable fonts specified 
with @font-face.
   - Deprecated namedspace binding has been removed.
   - Supported syntax for Length and <mpadded> values have been made 
closer to the one specified in MathML3 spec.
   - New MathML mirrorable operators for Arabic math.
   - Fix some bugs with the maction element.

* Firefox 16:
   - Change the default value for attributes mo@lspace/rspace to 
   - Selection attribute on maction is now considered by default.

* Firefox 17:
   - Update parsing for mtable@align

As usual, you can get a complete list of changes here:
