TIP and Fitaly support in Firefox
My GeckoTIP extension lets Firefox use the floating TIP like normal. This AHK script should work just fine alongside Firefox with GeckoTIP installed. Also, GeckoTIP actually has its own 3rd party onscreen keyboard popup built-in, and Fitaly is one of the programs it works with. If you're already running this script though, you probably should not enable the option in GeckoTIP to open Fitaly since they may conflict.
