Bye bye AccessibleHandler, you will not be missed.
The latest update to Firefox Nightly on Windows removes all traces of the old and slow architecture that gave us users and current and former Mozilla employees so many headaches, present company included. As of today, there is no way to invoke the old architecture any more, and the project formerly known as Cache-The-World is now the only way Firefox communicates web content to assistive technologies. Congratulations to the whole team! #Firefox #accessibility
