"Hide only last window", how it work??

[Questius]

Hi! Win7 x64, Firefox 45 x64, FireTray 0.6.0.1-let-fixed

I have set "Hide only last window". It works through time, sometimes last opened window is minimizied to tray on close by clicking X button of Firefox window, but sometimes in same situation, last Firefox window is fully closed (process killed) and icon disappeares from tray.

Possible I dont understand of logic of this addon?? I thouth it must always stay in tray while I not close window choosing "File -> Exit" in Firefox? It is possible to do such?

btw, I think I have found when it happens...

Try to do this steps:

1. make sure firefox is not run and no icon in tray
2. do first run of firefox
3. open any web page with links
4. open any one link in new window (use context menu or Shift key)
5. go to this new opened window and close it by X button
6. click X button on the first window you have opened to close it
7. you'll see that icon is disapear from tray and Firefox terminated from process!

If you will do first run of firefox and then close it without open any links then it stay in tray and in opened process. After it you can try 1-7 steps writed above and everything will work good, Firefox will stay in tray... So to work your addon correct I always need to do first run of Firefox, then close it and only after it your addon work correct, but I think it is not so suitable...
