Rated 1 out of 5 stars

The new version causes Firefox to crash almost constantly. Every time I hear the "Alert" noise I know I have at max five seconds to save all my work before I lose it all. It worked fine up until Firefox updated to the most recent version, and now both the browser and "Check 4 Change" do not play well together. Please fix it sometime soon -- its literally costing me money.

This review is for a previous version of the add-on (1.9).
