Need Single instance of FFP with mulltiple .exe's concurrent with installed FF
Getting Firefox is already running. Running installed FF 52.0.2 (32 bit) and Portable 2.0.4.1 as downloaded. AllowMultipleInstances=true and moved to FirefoxPortable.exe dir. Would like to have new tabs opened instead of new window. Many reported problems are looking for multiple instances and not what I am looking for.
