Yes, I noticed it. It seems to have appeared in Firefox 18.I never would have considered it something that I needed to fix.
It looks like your computer experienced a hard shutdown. Does it still show that message every time you boot?
Sure, it's possible.How are you viewing videos? (Flash or Webm?)
Does it help if you log out and back in to Cinnamon?
Also, are you a Dalek?
It was a few weeks ago that a kernel update caused some problems with Firefox.If you really want to continue using Firefox, then I'd suggest creating a new clean Firefox profile.

It's looks like there's some AUR packages that have what we want (as usual ). Try any of these that have "left_ptr" in the name. https://aur.archlinux.org/packages/?O=0 … _Search=Go
Also, the "man archlinux" is really simple, really concise, and really helpful for fixing those little warnings.
