145956 - problem with mouseovers using change of .src property

Status: CLOSED INVALID

(Core :: JavaScript Engine, defect)

Description

[Sebastian Schmachtel]

Since Mozilla 1.0 rc1 many mouseovers generate several js errors:
Error: uncaught exception: Permission denied to get property HTMLImageElement.src
or
Error: home2 is not defined
Source File: http://www.dlrg.de/Gliederung/Schleswig-Holstein/Kiel/legende.html
Line: 47
Even if I declare home2 correctly the second error remains!
These mouseovers run with NS4, Opera, IE4/5/6 and Mozilla up to 0.99.
Another example page wold be http://www.theregister.co.uk/ . It seems to be
exactly the same problem...

You disabled image rollovers in preferences at some point.  Quit Mozilla, open
up prefs.js, delete the line that sets the access policy for Image.src to
"noAccess", then restart Mozilla.

That will allow sites to access image.src again.

Marking Verified. 

If I add the following line to my "all.js" file:

  pref("capability.policy.default.HTMLImageElement.src", "noAccess");

and restart Mozilla, I get the same  error as Sebastian reported:
Error: uncaught exception: Permission denied to get property HTMLImageElement.src

If I change that line to "allAccess" and restart Mozilla, I don't get the error -

Thx a lot! 
This helped me a lot! 
I just wonder where/when I changed the policy for the image.src object...
