If you GNOME guys are getting addicted to the Firefox' smooth-scrolling feature (which is more of a GRE thing than Firefox) and would love to have it in Galeon or Epiphany, here is your trick. You owe me a good coffee (but not one of these):
- Fire-up your favorite GRE-based browser.
- Go to about:config (no typos here, that's exact URL)
- Find general.smoothScroll set it to true
- You're done.
Enjoy!
PS: I'm serious about the coffee.
