FF9.0 Noscript2.2.4 delayed cursor keys then hang
Posted: Fri Dec 23, 2011 6:09 pm
Firefox Bug 713254 - scripts hang when multiple cursor/page down keys are queued
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:9.0) Gecko/20100101 Firefox/9.0
Build ID: 20111212185108
Steps to reproduce:
Scripts cause significant slowdown in processing cursor/page down keys
[2-5 seconds delay before the first key is handled, 1+ second for the next keys].
If too many [10+] cursor/page down keys are queued the scripts hang Firefox.
After 30-60 seconds with no cursor/page down key the initial delay is in effect again.

Actual results:
