Maff add-on will NOT open any maff file saved previous to the latest update of version 41.0 of Firefox. The latest version of Firefox is NOT backward compatible - WHY?? Troubleshooting information below shows Firefox version 40 because I had to uninstall version 41 and re-install 40 to be able to view my previous maff saved pages. When can I expect a fix for this Firefox maff failure?? Or do you suggest I use another browser??
