Thread:Extension talk:VisualEditor/VisualEditor freezes at loading bar./reply (2)

I'm not a developer for this sort of thing, but there is some information not present in the console of my firefox browser. The best I can probably do is just regurgitate it. I have snapshots of my system I can go to and from at least so it's pretty easy to revert.

Before the import: Use of getAttributeNode is deprecated. Use getAttribute instead. load.php5:34 Use of attributes' specified attribute is deprecated. It always returns true. load.php5:34 Use of getPreventDefault is deprecated. Use defaultPrevented instead. load.php5:48 Use of document.createAttribute is deprecated. Use element.setAttribute instead. page-attachment.js:209 Use of setAttributeNode is deprecated. Use setAttribute instead.
