I have a Pavlovian annoyance response to noticing that I have inadvertently clicked a mailto link, because back in ~2005 firefox would try to start Evolution. I usually only noticed the click because of the sound of my spinning disk thrashing to try to lift into memory hundreds of MB of dependencies from their rust platter slumber. Evolution generally didn't even load enough to so much as show its splash screen before I found a terminal and killed the process tree.
