216585 - long temporary lockup with high CPU usage and vibrating mouse cursor when rendering googlesyndication.com add banner

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[James Paige]

Tested with Mozilla Firebird builds 20030812 and 20030818 (Linux GTK2+XFT)

Go to http://members.boardhost.com/OHRRPGCEHelpMe/msg/16523.html and Firebird
will appear to hang. The mouse cursor will vibrate, and the CPU usage for one
Mozilla process will skyrocket to 99%

After some time has passed (seems to vary, but I would say between 30 seconds to
3 minutes on my machine) it will unlock, and the page will finish rendering.

This is being caused by the googlesyndication.com add banner at the top of this
message board.

Attachment: the banner javascript, extracted from the page.

Here is only the banner javascript extracted from the page:

<!-- Creative for 728 x 90 format -->
<script type="text/javascript" language="JavaScript">
<!--
	 google_ad_client = 'boardhost_728x90';
	 google_ad_width = 728;
	 google_ad_height = 90;
	 google_ad_format = '728x90_new';
	 google_safe = 'high';
// -->
</script>
<script type="text/javascript" language="JavaScript"
src="http://pagead2.googlesyndication.com/pagead/show_scraped_ads.js"></script>


viewing it will cause the browser to hang for a minute or so.

And here is the remote .js file, in case it happens to disappear or change
