Rated 5 out of 5 stars

Disregard my previous message. It is indeed working after installing the Compatibility Reporter. For some reason, I received an incompatible message after installation. But when I actually uploaded like before, it worked. Thanks for the efforts Firefox team and Sankazim. Looking forward to further developments of this vital software.
