Better Zen

Zen Browser (based on Firefox) config changes for better speed, privacy, and security.
Inspired from the config tweaks Betterfox for Firefox Browser.

Zen's default preferences are already based on Betterfox (as mentioned here).
But there are a few differences, which are covered by Better Zen.

Tested with Zen version 1.0.2-b.3 Based on Betterfox version 133

How to use Better Zen

7. Back in the Zen Browser, under the new profile's name, use the Launch profile in new browser button to open a new Zen Browser window using the new profile.
