FYI, .. I did some testing with FF ESR 45 & ESR 52 ESR, but neither runs on openSuSE 13.2. I DID learn that both required the 4.14 update for mozilla-nspr, .. and, after this round of testing, I went back to the distro version 50 - and the LastPlugin now WORKS!! So, it appears that the major issue was the nspr version! Lee
