Status: VERIFIED DUPLICATE of bug 290777

(Firefox :: General, defect)

Description

[Darton Williams]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Error from Javascript console is:

Error: uncaught exception: [Exception... "Illegal operation on WrappedNative
prototype object"  nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" 
location: "JS frame :: http://mx.expr.net:81/javascript/global.js :: anonymous
:: line 58"  data: no]

This error did not occur in versions 1.0 - 1.0.2.

I have encountered this same error on several public sites which used to work
properly with previous versions of Firefox. URL's to come when I find them again.

Reproducible: Always

Steps to Reproduce:
1.Log in to http://mx.expr.net:81 with email address test(at)expr.net, password
test123
2.Move the mouse cursor over the "Refresh" icon at the top of the page 
3.Check JavaScript console for errors

Actual Results:  
Javascript error, email admin site loses most functionality

Expected Results:  
Responded properly to mouseover/mouseout and enabled image swap and clicking buttons

I believe this is a duplicate of #281552.

Comment 2

[Darton Williams]

I agree that the error is the same, and it may even be caused by the same issue,
but why did the javascript work in versions prior to 1.0.3? The user reporting
bug #281552 is using 1.0, and this particular error did not occur in that version.

Looks more like bug 290777 to me: same error in essentially the same code.
Workaround in the bug, plus a latest-aviary build should work right.

Reporter can you please re-test with a build from here (pre 1.0.4):
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-aviary1.0.1/

Comment 5

[Darton Williams]

Works with that build. Thanks, Jose.

Comment 6

[José Jeria]

This is wfm on trunk but broken in 1.0.3

duping to bug 290777, based on comment 3, please reopen if you feel that this is
incorrect.
