Hi,
I'm using jQuery in a Firefox extension to modify the current
document. It work great.
I only have problems with ajax request.
When you use getJSON in a FF extension the document object has no
<head /> but jQuery try to use it to add a <script /> tag.
The problem is located in the $.ajax() function.
The patch bellow fix the problem:
% diff jquery-1.3.2.js apwalfr/content/jquery.js
3433c3433,3434
< window[ jsonp ] = function(tmp){
---
> var w = window.content.document.wrappedJSObject ?
> window.content.window.wrappedJSObject : window;
> w[ jsonp ] = function(tmp){
3438,3439c3439,3440
< window[ jsonp ] = undefined;
< try{ delete window[ jsonp ]; } catch(e)
{}
---
> w[ jsonp ] = undefined;
> try{ delete w[ jsonp ]; } catch(e){}
3476,3477c3477,3479
< var head = document.getElementsByTagName
("head")[0];
< var script = document.createElement("script");
---
> var doc = window.content.document.wrappedJSObject ?
> window.content.document : document;
> var head = doc.getElementsByTagName("head")[0];
> var script = doc.createElement("script");
This way jQuery use the current window / document to add the <script
/> tag and everything work fine.
Don't know if this is 100% OK for all browsers but AFAIK
window.content.document.wrappedJSObject is only defined when you are
in a FF extension.
Hope someone can improve and apply this patch.

Gael
