In my last review I said Sitelauncher didn't work anymore in Kubuntu. I failed to mention that I had failed to turn off automatic updates in FF, so I have FF 55.0.4. So Sitelauncher doesn't work in Kubuntu 14.04 or 16.04 in FF 55. I turned on Windows today and Sitelauncher is working just like it has for several years. That's Windows 7 SP 1, FF 54.0.1 (had auto updates turned off, already). I don't know if it is the different OS's or the different versions of FF that's causing the problem (or the new Sitelauncher install instead of upgrade in FF 55), maybe a combination of two or all of those. Personally, I think the main culprit is FF with these new, unnecessary changes. Sorry about blaming Sitelauncher as the sole contributor when it may not be the problem at all.
