Have you tried Comodo?
They have Comodo dragon based on Google and also Comodo Ice dragon based on Firefox.
Also have one of the best firewalls, Internet security and anti virus programs you can find.
Go to
https://www.comodo.com Look down on the left hand side and click on "Free Comodo Downloads"
Be sure to click on the Free Comodo Downloads and everything there is free....
I have used only Comodo for the past few years and I've never had a problem with it.
Comodo Ice Dragon is based on Firefox and Comodo Dragon is Google based.
Try it, I think you'll like it. If not you can also delete and try sometime else.
I also keep a downloaded copy of the install.exe file in my document folder just in case but have never needed to do a reinstall.
