Firefox IE addon leak?

Hi

Do any of you FF users, know if the memory leak bug in IE tab add on is fixed?

My reference:

http://kb.mozillazine.org/Problematic_extensions

I do not know whether the info in this site is frequently updated , any how, I did not find any other opposite statement or update relating to this issue.

Thanks

It was just updated and a new version was released on December 3, 2008 however I don't know if that fixed what was wrong with it since I don't use it.
