[Bug 990997] [NEW] Slow typing in Firefox

[skalka]

Public bug reported:

Typing is extremely slow in typing in multiline fields. This happens
with the text field on twitter, google+, blogger. Usually there's a big
delay between typing and charachters to appear and cpu works a lot.
Everything works fine with other browsers like chrome or opera.
Disabling Javascript doesn't solve the issue even because withut js it's
impossibile to load text fields that make a large use of it. My pc is
equipped with a nvidia 8400gs m video chip. Let me know if more
informations are needed.
