Rated 3 out of 5 stars
Would definitely use this addon if it had "Minimize to tray on startup" option (like MinimizeToTray Enhancer) and option to disable "Restore Window" and always open blank one. This would provide real "turbo" mode.
Also I still don't understand how restoring windows works. If I close one window it can be restored but if I close two windows sequentially none of them can't be restored.
And yes, there is nothing about FireTray on the website you have link to.
Everything else seems to work smoothly. Nice work!
