On Safari, on my MacBook Pro running OS 10.14.3, I have installed the LP plug-in (several times because it keeps prompting me--a nuisance bc there is no verification that I have been successful...). When I attempt to "launch" a site--either by "quick launch" or from my "vault"-- (example, USAA) it does not launch. I never had this issue with the old version of LP and the old plugin. This needs to be worked-on, doesn't it? No need for launch failure!
