When using Toggle Software‘s ToggleMINIMIZE with Mozilla Firefox and/or Mozilla Thunderbird, you may find that it’s not minimizing to the tray as it should. You need to set a preference in the Moz apps before it will work.
I totally stumbled upon this by accident. I was investigating Firefoxes’ atrocious memory handling and how to deal with it. I found the
config.trim_on_minimize Mozilla preference (FYI, I’m still evaluating this to see if I like what it does). After restarting FF and TB, they started minimizing to the tray all of a sudden! To verify that
config.trim_on_minimize was the fix, I removed that pref, restarted and tried to minimize to the tray. It didn’t work. So, there’s your fix for that, found on a fluke.
See Mr. Tiensivu’s blog for more info on the Mozilla preference.
