disregard prior review Rated 5 out of 5 stars
after several attempts, i finally got it installed and it is a great add on. still bothers me that the message continued to appear.This review is for a previous version of the add-on (0.19.3).
installing issue might be caused by new version updating
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.
