Anyone have a recipe for getting Endpoint inspection application (the F5 VPN) working with Ubuntu 16.04.3 LTS with FF 54?

I have it working now. FF on Ubuntu doesn't seem to work right at all - I was never able to download the f5vpn .deb file, just f5epi. Then, I tried chrome, it downloads the f5vpn debian package file, when you open with Ubuntu software package manager, it doesn't install. so, saved it to disk, then used dpkg -i and voila it appears to be functioning ok.
