Windows 7 x64Using Firefox 26.0Intel QX6850/8GB DDR2/SSDI put Firefox thru it's paces - at any time i have 100+ tabs open spread among several TabGroups representing different projects. Of course re-starting Firefox only loads pinned tabs and the last tab on the active TabGroup.I've been using ACM for a few months, it always does good job finding and clearing target cookies. But it's S-L-O-W. Upon opening the ACM add-on, Task Manager shows Firefox as "Not responding" for at least 1 minute before ACM allows me to type domain name into search filter. And once i start typing it grinds again between individual letters. Seemed to get worse over time until finally today it failed to respond after @ 5 minutes so I had to crash Firefox. When it came back up ACM worked but again slow as molasses between individual typed letters in search filter.As a part of weekly hygiene I completely clear the following:- Cookies- Cache- Active Logins- Site Prefs- Form/Search History- Offline Website DataI'm sure it's due to the heavy demands i make of Firefox, but Firefox itself is fine, as are all other add-ons.+3 stars because it does what it promises, so the design is fundamentally sound ... but it has serious resource-efficiency issues (-2 stars).

This review is for a previous version of the add-on (5.6.1-signed). 

Waiting for 2 more stars..

In the recent version (5.7...awaiting full review) of ACM, I have made a few changes, which improves the performance of the filters. I even tried with huge data and found reasonably fast enough. Hope, it meets your expectations this time.

Let me know, if you still see the slowness.
