DragMath crashes Firefox

1. Be sure that either Tex Filter is activated or Site Administration > Plugins > Text editors > TinyMCE HTML editor > Insert equation "Require TeX filter" setting is unchecked
2. Using firefox version 24 open any page that uses the HTML editor and click the Insert an equation tool
3. Verify that firefox don't crash and Dragmath editor is working

Note: you will see a security warning saying that the application editor is unknown and you will need to check the box saying that you "accept the risk" and want to execute the application. Later when you click on the "Insert" button of the Dragmath dialog you will get another security warning asking you if you authorise this action. Life is really hard for people wanting to use java applets now, but all these problems aren't really Moodle's problems and are not the subject of this issue
