This candidate fixes a couple bugs we found in the first release, in
particular an issue with the node being passed to context menu item
callbacks (bug
561547) and issues with the XPIs being generated by "cfx xpi"
that prevented them from being accepted by AMO (bug
561503).
If this build looks good, we plan to release it as the final release
on Wednesday, April 27. So now is a great time to test it out and
let us know if you experience any problems using it!
