I want to keep using Firefox, but the performance gap between it and Chrome keeps getting worse. My bank's online site takes upwards of 2 seconds to redraw in Firefox now when I scroll, whereas in Chrome scrolling is virtually instantaneous. Same thing with Google Streetview. PDF rendering in Firefox and Thunderbird takes upwards of 20 seconds to render the first page of common documents, while evince is a few hundred milliseconds. This is on my latop running recent Fedora. I'm still mostly using Firefox, but my patience is almost done.
