Definitely back to Firefox. With all the non-standards compliant features that have been built into Chrome recently, it's a lot slower than it once was. Plus the less support Chrome gets, the less chance they have of destroying web standards. Just watching how Google handles the Android ecosystem should be enough to prove to anyone what would happen if Google had more control over the web. These days if you want an open web, you pretty much need to be at least Google-wary.

Firefox has also made leaps and bounds in memory usage and keeping the UI good looking but usable. Definitely a project worth supporting.
