Permission denied to get property Proxy.InstallTrigger -- on wrong page?

[Scott M. Sanders]

I have Firebug 1.9.0b1 up on an HTML page I downloaded. (It's from a site I made so am debugging.) I also have some other sites up in other tabs and sometimes click Facebook like buttons, login with Twitter, etc.

Why do the following errors appear in the Firebug console on the downloaded HTML page, when Firebug is not enabled on the other sites? It's confusing as they look like they're from the downloaded HTML page, but they're not...

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

uncaught exception: Error: Permission denied for <http://platform.twitter.com> to get property Proxy.InstallTrigger

What exactly does somebody have to do to see these errors?

So the downloaded page does not include a Like button or the twitter widget?

Do you mean you open the file from the file system?

Got the same error with Firebug 1.8.4 on Firefox 8 on Ubuntu 10.04
(via firefox-stable ppa). The message says "uncaught exception: Error:
Permission denied for <http://warschau.europa.ariva.de:881> to get
property Proxy.InstallTrigger".
I am a Web Developer and "warschau" is the name of my pc. I'm testing
my site locally.

Please, provide a test case that can be used tosee the problem on our machines.
Otherwise I don't know how to fix it.

- Open a local HTML file in Firefox.
- Enable Firebug on this page if not already.
- In a new tab, go to a site that uses a Facebook or Twitter login. I
just used CNET Tracker.
- Do not use Firebug on this site. (I'm not sure if this is necessary?)
- Login to the site with Facebook or Twitter.
- Go back to the first tab, and see an error in Firebug console.

Thanks!

I can also reproduce it now, reported here:

I wonder if this is related to the Illuminations for Developers
extension.
- Turn off this extension, do the errors go away?
Also try:
- enable the extension
- clear your cache
- go to whichever test page you're dealing with
- open your cache in a new tab: about:cache?device=disk
- do you see entries like this:
http://platform.twitter.com/widgets/tweet_button.html?count=none&url=http%3A%2F%2Fwww.illuminations-for-developers.com%2F&via=illuminations4d&related=sroussey&text=%23Illuminations%20for%20%23Firebug%20is%20awesome!%20Give%20it%20a%20try!

"Illuminations for Firebug is awesome! Give it a try!"
What is going on here? It the extension attempting to tweet on my
behalf? :/

It just fetches the Tweet button. But Steven (the author of Illuminations) can surely tell you more.

Do you actually see the "Permission denied to get property Proxy.InstallTrigger" problem? It should be fixed since beta 2 of 1.9. So did you already give Firebug 1.9.0b4 a try?

I was receiving a steady stream of these messages about Facebook and was baffled as the site I was developing had no facebook extensions, I thought Firebug was picking up on the open Facebook tab I had open in my browser, recently I noticed a similar message about twitter, knowing I did not have twitter open or the api on my site I decided to check. I viewed the source of the page that was generating the error and found 1 reference to google, removing this has quietened Firebug. The culprit for seems to be the lines:
<!--[if lt IE 9]>
<script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

this is a reference added by Dreamweaver to a webpage using the HTML5: 2/3 column fixed templates.

Sorry, yes, the latest firebug has no issue. I didn't realize I was so
out of date.
Thanks

We didn't release the final 1.9 yet, so you were not really out of date. Good to know, that the error is gone now. Thanks for the feedback.
