Horrendous

Chrome has been unusable for a week or so. I couldn't log into some websites, some websites would be corrupted. All thanks to this extension (finally figured that out). As someone else said, this effectively destroys any java running. Something to stay away from.

Crashes all the javascript on chrome

Highly unreliable, just recently started crashing everything on chrome and made chrome unusable. Upon investigation found out that it was this extension as the javascript completely stops working on chrome. Used to be good but not anymore.
