I'm sorry, probably my question was answerd earlier, but I can't found!
(I missed "sub-forum specified search feature" here)
I want install "FirefoxPortableESR_52.3.0_German.paf.exe" at memory-stick, for portable use.
I use local, persistent, a Firefox-Portable-Edition, updatet to V54.0.1 (64Bit).
Now, the Installer of the "FirefoxPortableESR_52.3.0_German.paf.exe" refuse the installation while the local firefox is running!
The local firefox is configured for multiple instances with "AllowMultipleInstances;true" in the "about:config"
I want no close my local Firefox, because informations from www are wishfull or important while working!
Any hints, ideas?
