I really like this extension. I realy do. But for the past two weeks my CPU has been going crazy and I could not figure out why. When I finally narrowed it down to this extension I thought of cryptocurrency mining and left a review stating my suspicion. I might have been wrong, as the developer assured me this extension is not mining cryptocurrency so I deleted the review. This still leaves me with the cpu hogging issue which was not present before January the 5th.
