Online actionscript help reference causing problems in Firefox 19

[Kevin_Sherrill]

Just discovered this. I upgraded to Firefox 19 yesterday. I'm only running the NoScript, DownloadHelper, and Firebug plugins. If I pull up a Adobe help page such as:

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObject.html#...

then it will start causing Firefox to experience horrible lag. I know this because if I have Pandora running in another tab the music will start breaking up until I close the tab with the Adobe help page. NoScript is set to allow Adobe.com and this has never happened in previous versions of Firefox - the tabs used to coexist with no problems.

If things worked properly before that upgrade... wouldn't this be a problem with Firefox, and not Adobe?

I just went to that page on Firefox 19 and navigated around that page; I did not notice anything abnormal.

But if you look at that page source you will see that there is a large amount of Java scripting going on.  Perhaps a bug in Firefox 19 JS engine?
