need help Macro in firefox not running

[Gintaras]

Firefox does not have IHTMLElement2 etc. If want to find all <span>, use FFNode. However it does not have functions to get element position, therefore need to convert to Acc, which not always works.

#sub Callback_Acc_FindFF
function# FFNode&x level ARRAY(FFNode)&a FFNODEINFO&ni

;Callback function for Acc.FindFF or FFNode.FindFF.

;x - current node.
;level - level of x in the tree. It will be 0 for the root node, 1 for its children, 2 for their children, and so on. By default, the root is the #document node of web content; its children are such nodes as DOCTYPE and HTML; HTML childeren are HEAD and BODY.
;cbParam - cbParam passed to FindFF. Can be declared as reference to any type.
;ni - node info, as retrieved from FFDOM.ISimpleDOMNode.get_nodeInfo(). To use the strings easier, assign them to str variables, because they are BSTR.

;Return:
;0 - stop. Let x will be the found node.
;1 - continue.
;2 - continue, but skip children of x.
