after several attempts, i finally got it installed and it is a great add on. still bothers me that the message continued to appear.

Это отзыв для предыдущей версии этого дополнения (0.19.3). 

Thanks for the great patience and adjusting the review. Sorry for the inconvenience while installing. I had the same frustrating experience myself before. It appeared to me that there was a period of time after the updating of a new version during which the error message "corrupt file" shows up while installing. My update from version 0.19.1 -> 0.19.3 was just got approved by Mozilla Add-ons reviewers at 12:27pm EDT, like an hour ago, and there must be some file replacement on the addon website. I was hoping that this wouldn't happen every time but it seems like a constant issue now. I'll try to report it to someone.
