Comment:

Two things that are likely to cause problems here, especially when combined:

  • Firefox is very problematic because of the way it only allows a single instance at a time - by the time you start it again, it may still be confused about where it should run and try to run in the instance that you are shutting down. We are keeping track of commands that can only be run once and you should get a notification warning (DE permitting) when you try to start a second one. Except... if we are shutting it down or if it is stuck, then you may have more problems.

Not much more we can do about that I don't think...

  • Session pre-loading and pre-connecting: this is what is causing those extra sessions you are seeing. Xpra is so fast to start that it makes little difference to startup time. When this is enabled and working properly - there is no difference to startup time between a local app and a "remotized" app, with it disabled you have to start the xpra server and client for each application - which may take about half a second.

To disable this feature, edit: 

.winswitch/server/server.conf

And disable: prelaunch_enabled then restart your server (or applet). Does this help?
