Off topic: I don't know if it's Firefox, GTK or some other component at fault but all tooltips in the browser last for an unreasonably short amount of time and it's really hard to read something more than a couple of words. I have to either view the page source or freeze the process. I wonder why a tooltip is supposed to disappear in the first place.
