If I press and hold a link or picture on a webpage, a little menu pops up. This menu has at most two lines of text for the alt-text/tooltip/link destination. Even in landscape mode, this can be insufficient for the full text. How do I make it show more than just two lines?
By the way, I like m.xkcd's method. But is there really no about:config entry to configure the amount of title-text shown?
