I've been using this for years. I updated to the latest version and I noticed that Firefox's CPU utilization was running at 30-40%. I tried disabling the addons one at a time. This turned out to be the culprit. I'll just wait for the next update.This review is for a previous version of the add-on (22.214.171.124.1-signed).
