I use the Chromium daily PPA for Ubuntu. And for a few days now, Chromium has been showing abnormally high CPU usage. It basically locks up a core, and when you have only a dual core machine, things get bad and ugly. The only saving grace is that I can shutdown chromium rather painlessly as usually, only one process is responsible for the CPU lockdown,.
My cribs against Firefox still stand, but a quirky browser is better than a useless browser.
Back to Firefox then, :|
