If you liked Chrome, but it's no longer supported under 10.6, you might try the Epic Privacy Browser, which is available here: https://www.epicbrowser.com
What Epic is:
It's the Chrome "engine", but with ALL the "google stuff" stripped out. But there's more to it.
Epic is designed from the ground up to protect user privacy. It will block trackers, and do "secure searching", and even more, it can "cloak" your IP address (make you invisible to other web sites).
I don't have any issues with Firefox and I use it on occasion myself. Normally, I use Safari though. At the office on my Windows PC, Firefox is my main browser.
