I can't see that error at Google Chrome 18.0.1025.162 for Linux (Ubuntu 10.04.4 LTS).

'getAttributeNode()' and 'specified' problem is wikimedia bits's problem, not mediawiki.

And I can't testing first error since I don't have IE7.

The warnings shown in Firefox are not related to MediaWiki and are not important problems. They are from jQuery internally and they will fix it upstream when needed.

The error "Unterminated string constant" shown in IE is not related to the Firefox warning but is a real bug. Rephrasing summary to emphasize that instead.

Note that from looking at the screenshot, it looks like this error is caused by a user script or site script from en.wikisource.org not something we can fix in the software.

There is bad syntax for IE in a local gadget, nothing for bugzilla -> INVALID

https://en.wikisource.org/wiki/MediaWiki:Gadget-Edittools.js contains a extra comma for a array definition.

Remove the comma in the following code snippet:

			$choise.show();
			$sections.not($choise).hide();
		},
