Now Google transmits user locations

I think I've provided enough details. Safe browsing blocks malicious websites, even though it uses Google. Search suggestions doesn't matter, since you'll search for the thing anyhow.
geo.enabled might be needed by some online services, and Mozilla states it's opt-in, so there's little point to disabling it.

 

That's easily mitigated with just 2 measures;
-Insert 2 table tennis balls in cheeks.
-Inhale helium.
-Start call.
-Ignore staring bystanders.
-Finish call to mom.

 

If you were driving somewhere, and went off the road into the woods and hit a tree, later reported missing, you'd be glad that you had the GPS.

 

This is true however it also has room for abuse. It is a two-edged sword imo.
