Description

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0  AC/4.0
Build ID: 20111104165243

Steps to reproduce:

nothing special just visited my normal day to day websites you can visit them

http://www.facebook.com
http://www.twitter.com
http://www.huffingtonpost.com
http://www.engadget.com



Actual results:

Error: uncaught exception: Error: Permission denied for <https://www.facebook.com> to get property Proxy.InstallTrigger
Error: uncaught exception: Error: Permission denied for <https://www.twitter.com> to get property Proxy.InstallTrigger



Expected results:

no error should have been triggered since the said websites worked fine in 7.0.1

I have disabled all the addons & themes short of deleting my profile and i keep getting the same error and its not just those 2 websites its seems all websites who linked to a social platform even my private website suffer from the same problem

I can confirm this issue apparently triggered by the Twitter Intent and Facebook Like buttons with UA Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0

A comment on a Twitter Help Center article confirms the issue also on Windows 7 64-bit. (https://support.twitter.com/groups/32-something-s-not-working/topics/133-top-issues/articles/266189-blank-screen-on-login -- by user @xbsaint)

Can confirm this issue on other Web sites, including those I develop.

I can also reproduce with FF8, on all sites I visit with the FB Like button.

We at Facebook have no idea what's causing this, but would love to fix it if it's something on our end. Let me know if I can help.

more details on the Origin tag? I went through the 8.0 release notes and bug list but I'm not sure what you're referring to.

i'm getting this error in firebug:

uncaught exception: Error: <http://www.facebook.com> wurde die Erlaubnis für das Lesen der Eigenschaft Proxy.InstallTrigger verweigert.

Just FYI, this is apparently a Firebug issue, not a Firefox issue: http://code.google.com/p/fbug/issues/detail?id=4991

Comment 10

I confirmed in the Firebug ticket that this issue was fixed in Firebug 1.9b2. It is not a Firefox bug.

Comment 11

This error is raised without Firebug installed.  Perhaps Firebug is now masking the error, but this still looks like a Firefox problem to me.

Comment 12

I can also get this in FF 8.0.1 with Firebug 1.9.0b2 and also with all add-ons disabled. So it looks as though there's something more that just Firebug involved (see comments on http://code.google.com/p/fbug/issues/detail?id=4991)

An example page is : http://www.justshowof.com/demo/socialButton

where I get Facebook related errors on the fisrt load and Facebook AND Twitter related errors on a refresh.

You are correct, Adam. Firefox's error console does show the exception being thrown. Hadn't looked at this before (so used to using Firebug for everything; not a core Gecko dev.).

This is probably a FF bug as you said.

This error can be simply triggered by setting document.domain to any valid value in any webpage using javascript. For example, assuming the follow page can be visited by http://foo.com/bar.html.

------------------------------------
<!DOCTYPE html>
<script>
  document.domain = 'foo.com';
</script>
------------------------------------

Then the error message "uncaught exception: Error: Permission denied for <http://foo.com> to get property Proxy.InstallTrigger" shows in the error console.

so, now what? the errors are still happening - from Facebook scripts; and it seems like it is affecting other JavaScript scripts.

FireFox 9.01
FireBug 1.8.4

I have recently added a Facebook Status Link to our website:  http://smutsniffer.com
Code below is a copy/paste from Facebook:

<script>
(function(d, s, id) { 
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>

FireBug Error: uncaught exception: Error: Permission denied for <http://www.facebook.com> to get property Proxy.InstallTrigger

It appears the javascript is trying to connect using http instead of https.  For some reason it is not "forcing" a https (secure) connection.  

Here is the all.js Facebook function that should be utilized, but is not.

FaceBook all.js from: http://connect.facebook.net/en_US/all.js#xfbml

if(FB.initSitevars.forceSecureXdProxy)b=true;var g=FB.getDomain((b?'https_':'')+'cdn')+FB.XD._xdProxyUrl+'#';


Hope this helps...

+1 reproduced

And I am afraid this bug sometimes affect other scripts !

I am seeing this error in my error console at gmane.org with Firefox 11 (Aurora) without having Firebug installed.

I am having problems viewing and creating email on my hotmail account at mail.live.com ... and noticed tons of several errors that say:

Error: uncaught exception: Error: Permission denied for <https://snt109.mail.live.com> to get property Proxy.InstallTrigger

Error: uncaught exception: Error: Permission denied for <https://secure.shared.live.com> to get property Proxy.InstallTrigger

Could these errors be affecting my ability to view/create email?
Has the source of these errors been found?

I forgot to mention more details: Windows 7 x64, Firefox 9.0.1, addons disabled, cache cleared, cookies deleted, restarted firefox... and still got those errors.

Also, I constantly get a message within my hotmail tab that says:
We've updated Hotmail, so please refresh your browser or close it and sign in again. If you are composing a message, make sure you save it as a draft. 

... even if I've deleted the cache/cookies and restarted!

I'm wondering if it might be related to the uncaught exceptions...  There are also several dozen css warnings that the page spews out.
I see it also with Aurora daily build, Windows 7, pretty mpuch no plugin installed, fresh machine, never logged in to facebook

Yes, but not so simply.  If I write document.domain AND window.open() I get the Proxy.InstallTrigger exception.  Either by itself is harmless.

Further spookiness, the exception happens at window.open() time but cannot be caught.

Example (visibone.com/pderror.html):
------------------------------------
<script>
	// Full error message on the error console (Tools | Web Developer | Error Console, or Ctrl-Shift-J):
	// Error: uncaught exception: Error: Permission denied for <http://visibone.com> to get property Proxy.InstallTrigger
	try {
		document.domain = document.domain;              // If I do this...
		alert('Before "uncaught exception"');
		window.open("http://mozilla.org/favicon.ico");  // ...and this, then I get "uncaught exception" on the error console
		alert('After "uncaught exception"');
	} catch(e) {
		document.write(e.message);
	}
</script>

------------------------------------
Firefox 10.0, Win2K, no FireBug

I also noticed this error on FF 10.0.1 when I code with an Iframe and javascript, even with the same domain or hostanme for the iframe link.
this exception was not visible on FF 6 and earlier
