No instructions that I can find on installing on a Mac. I had to rename the file as a .zip file because my Mac said it didn't have the software to open the .xpi file. Zip worked and the folder opened, but don't see instructions and there is no obvious (to me) install file. Can't get it installed on a Macbook. Anybody have instructions to do it? Your help would be much appreciated.
