Too slow on heavytabbed browsing Rated 2 out of 5 stars

I am, probably, tab addict. Right now i have around 1000 tabs (need to clean them, right), at least most of them suspended.
I tried this addon to clean some mess but...after installing Firefox become slow like slideshow. Looks like that load is too big for this addon.
At same time i use All Tabs Helper which do something similar, but with less fancy way and its works with no problem.

This review is for a previous version of the add-on (1.7.1-signed.1-signed). 

Hi, we've just released v1.9 which may solve these problems for you. Since it's currently in the release queue, the manual upgrade to v1.9 can be done here
