If you haven’t noticed yet, Firefox 3.5.4 hit the web last night. For accessibility, this brings one major fix all of our Linux and Solaris users will appreciate: Certain comboboxes such as the “Security Question” one on the GMail signup page, were broken in the initial releases of 3.5. When you arrowed, Orca would not speak the newly selected item. This was a regression from 3.0 where this worked.
We initially fixed this for Firefox 3.6 alpha and now also backported the fix to the 3.5 branch.
