Corrupt file? Rated 5 out of 5 stars
Firefox reply that could not install.Possible corrupt hash or invalid file.5 stars for the idea,but i hope that the author will resolve this big issue.This review is for a previous version of the add-on (0.4).
Could you tell me what Firefox version you're using? I just checked on beta 7 and 3.6.12 and it seems to be working fine. Thanks!
