TL;DR: try recompiling everything. You can ask emacs to, or you can just force it to:

find ~/.emacs.d -name "*.elc" -delete

Then restart emacs.

The main culprits for this error are:


I recently had to uninstall/reinstall my brew casks and recipies because I had royally screwed something up. I have a script to re-install all the things I want so it was no drama except for the downloads and re-install, and some oversights when I uninstalled brew. So here is what I think I should have done:

1. uninstall any applications installed with brew cask

$ for APP in $(brew cask list); do
  brew cask uninstall $APP

What to run:

rsync -HPva --delete <source>/ <dest>/

(tip for remembering: "Arr! Sync! Hey, Pretty view, eh? Do Eet")


  • -H (--hard-links) sync any hard links as hard links, as distinct from files, at the destination
history -d $((${HISTCMD}-1));history -d $((${HISTCMD}-1))

This should only be necessary on platforms where Firefox isn't honouring the global setting. For instance on a Mac or Windows it's not necessary if you've set the scrolling direction to reverse globally, but on Linux, Firefox doesn't honour KDE's setting. I haven't tested GNOME ….

The default setting is fine for an actual mouse-wheel, but when using a touchpad to two-finger-scroll (or a trackball), it's more Natural for the page to scroll down when you swipe your fingers up: it seems more like how a paper page will shift.
