Chrome suffers from gluttony. I need to restart it 10-15 times a day as it starts using gigabytes of memory. When I have 10-15 tabs open, my MacBook Air fan is always on. Safari is the best. For tabs with the same URLs, it uses times less memory and CPU. I've used FirefoxDeveloperEdition for a while and I still prefer it over Chrome. I only got mad once as One-Tab data file (a single JSON) got wiped out, and a few thousand links disappeared from this universe forever with no way to restore it. Then I spent the last four months using Chrome and I'm going back to Firefox, which has the best balance of features and gluttony. I really had a much higher opinion about Google's engineering talent, but the growing pile of crap that Chrome is becoming is starting to stink beyond tolerance.
