That makes no sense. How would they really protect one's privacy???

Ask them.

"Browsers: Can They be Trusted? " I've never thought so.
Long time user of NoScript (I use Firefox). For me 95% of the time I don't need J$ being able to run, the other 5% is for YouTube. I also use Better Privacy and DoNotTrackMe. I don't allow cookies except for here and 2 other places, 3rd party cookies aren't allowed at all.
I use Ixquick and Startpage for searching. In about:config I turn off clipboard autocopy and geo.enabled as well. Every thing gets cleared at the end of session and then Bleachbit gets run after closing Firefox.

Well, those are just words. You are the only one who can protect your privacy on the Internet. I think there can't be any confusion, it's obvious if you know how Internet works.

Indeed - they also conveniently fail to mention that google tracking, in the form of "safe browsing", is in fact built into Firefox and enabled by default. The "do not track" option is also pretty pointless as you're blindly trusting a 3rd party not to track you.

You are saying Mozilla/Firefox routes everything a user does through Google without their permission or knowledge? Just where does one "turn this off" if possible? I don't see an option for such a function.

Basically you are deleting private data only on your computer.

As others have pointed out, IP domains identify the country and so country specific ads.
Most sites get you to use your e-mail id as an identifier. So they build associations with this stored id.

OK

Not exactly, safebrowsing does send identifying information about you, your browsing habits and your system to google however. So if you tried to access some site and safebrowsing blocked it, it would certainly log the info on google's servers... (This is why tor browser has it disabled by default).

In fact for safebrowsing to work, it has to check the url of every site you visit against their database... this involves transmitting information and it's safe to assume that this information is logged every time. So yes it's just tracking wrapped up in a "secure/safe browsing" package to make it easier to swallow.

Mozilla don't get their google $$$'s for nothing...

Enter "about:config" in the address bar, accept the "disclaimer". Then change
to

Thanks.
Greatly appreciated.
