Firefox running slowly
I'm running Firefox 16.0.2 on Ubuntu 10.04.
It is now running slowly in opening some web pages, the window frequently goes dim and I have noticed from my ADSL modem that there is no traffic until the window goes bright again.
Could this be something to do with Mesa? If so is there a fix/bypass please?
I note that I do not get any problems with the Chromium browser 22.0.1229.79.
