Problem with Noscript 2.6.8.15rc5 with mozilla-inbound build

[koron]

With Noscript 2.6.8.15rc5, some sites don't work normally on firefox (at least mozilla-inbound build, I haven't test with other tree yet...)

One case is below:
http://www.yahoo.co.jp/
(Japanese site)

1. Open page (Left tab(『ニュース』) is focused in topic box at center of page)
2. Click other tab in topic box.

Expected:
Tab clicked is focused and topics in box are changed.

Actual:
Tab clicked is focused, but topics aren't change at all and "TypeError: can't access dead object" is appeared in Error Console

Regression range:
2.6.8.15rc5(probably)
At least, sites work normally with Noscript 2.6.8.14 or Noscript is disabled.

EDIT:
Fixed in rc6. Thanks for good working.
