"Unsafe JavaScript attempt to access frame with URL…' error being continuously generated in Chrome webkit inspector

Chrome (or any other webkit browser) throws a ton of these "Unsafe JavaScript attempt to access frame with URL..." when working with the Facebook API for example.

How does facebook rewrite the source URL of a page in the browser address bar?

Go to http://www.facebook.com/facebook?v=wall , then click on the info tab. The content will be loaded, and the address bar now becomes http://www.facebook.com/facebook?v=info but the webpage didn't reload.

Webkit 3D CSS. Rotate camera like in a First Person Shooter

What I want to achieve is a camera rotation like http://www.keithclark.co.uk/labs/3dcss/demo/ . It's not perfect and sometimes the camera breaks, but that's the idea.

How does the paste image from clipboard functionality work in Gmail and Google Chrome 12+?

I noticed a blog post from Google that mentions the ability to paste images directly from the clipboard into a Gmail message if you're using the latest version of Chrome. I tried this with my version of Chrome (12.0.742.91 beta-m) and it works great using control keys or the context menu.

Why does this javascript based printing cause Safari to refresh the page?

The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth.

The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/

Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way.

Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided?

P.S.: On my real site the same occurs with Chrome. In the example fiddle Chrome seems to not show the same behaviour as Safari, though.

Edit: I also tried to have the printing button on a different tag than an a anchor, like span or button , but that didn't help with the problem.

Edit: I run into this problem with Safari 5.1.2 on Mac OS 10.6.8. In the jsfiddle example, the behavior shows as a white "flicker" that covers the whole browser after having clicked the print button and closing (either printing or aborting) the print dialogue.

Edit: Just started a bounty for this question, as I am still looking for an explanation for this browser behaviour. I am more than willing to give more details on the issue. From my experience on SO it is not adviseable to post links to online pages, however I feel the problem is really hard to reproduce. I think the "flicker & re-render" I experience with the posted jsfiddle is hopefully is result of the same problem.

Edit: As explained in the comments, opening a new window containing the current state of the application, then printing and closing that window, might be a fix, but I don't consider it a sufficient answer to the problem at hand.
