What steps will reproduce the problem?
1. Launch svg-edit in Firefox 6.0 on OSX 10.6.8
2. Click on Main Menu and select Image Library
3. Select Demo Library Local

What is the expected output?

What do you see instead?

Data URL conversion failed: [Exception... "Security error"  code: "1000" 
nsresult: "0x805303e8 (NS_ERROR_DOM_SECURITY_ERR)"  location: 
"file:///Volumes/RamDisk/svg-edit_aid_r2038-2011-08-26/extensions/imagelib/index
.html Line: 44"]

In what browser did you experience this problem? (ALL, Firefox, Opera, etc)

Firefox 6.0 on OSX 10.6.8

In what version of SVG-edit does the problem occur? (Latest trunk, 2.5.1,
etc)

svg-edit - Revision 2038: /trunk/editor

Please provide any additional information below.

Above steps and insert of logo.png has worked on previous versions of Firefox 
on OSX 10.6.8 and earlier with svg-edit - Revision 2038: /trunk/editor.

Attempt to load logo.png from "image library"

results in Data URL conversion failed: [Exception... "Security error"  code: 
"1000" nsresult: "0x805303e8 (NS_ERROR_DOM_SECURITY_ERR)"  location: 
"file:///Volumes/RamDisk/svg-edit_aid_r2038-2011-08-26/extensions/imagelib/index
.html Line: 43"]

Perhaps better error use with this type of try/catch script for firefox.
Replace the "var imgd = ctx.getImageData(x, y, 1, 1)" with your getImageData 
declaration:

try {
 try { 
var imgd = ctx.getImageData(x, y, 1, 1)  
    } 
catch (e) { 
        netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
var imgd = ctx.getImageData(x, y, 1, 1) 
   }
 } catch (e) {throw new Error("unable to access image data: " + e)
}

However, a complete fix to restore usability is preferred!

Thank you.
