Would love to know your pm message - I have this issue as well - updated to 10.14.6 and Firestorm won't even open. Restarted my computer multiple times. reinstalled Firestorm. Anyone else? Frustrating I'll take it a step further - I can't open either Firestorm or SL Viewer - white screens with rainbow of death..... WTH!
