Most of those features are rendered moot by cookie blocking, NoScript and POPS with Thunderbird. It occurs to me though that you use Customize Google to prevent clicktracking and removal of UID.
I don't block all cookies, (third party only), but all cookies are cleared when I exit Firefox. And blocking cookies won't give me back the screen space occupied by Google's ads.
Using Thunderbird is OK when I'm sitting at my PC, however when I'm on the road with a laptop I use the web interface - I don't keep email on my laptops.
And it's not removal of UID, it's anonymising it.
So to sum up:
Allow cookies = get ads, waste screen space.
Disallow cookies = No Google account access at all.
Use Customize Google = Google account access, no ads, customised search, force Google pages into https, lots of other options to happify my Google experience.
I could whiz up a GreaseMonkey script to do the https, no ads, etc, but why bother when someone has already created a add-on that takes care of it and adds a few more things ?
Why would you be concerned only about Google and no other corporate entity?
I visit corporate websites very rarely and NoScript is still running when I do.
And what's with the Spanish Inquisition, (not that I expected it) ?
You, being paranoid, should just accept that the more layers of obfuscation between yourself and everyone is a Good ThingTM
EDIT: Sorry, noticed you said corporate entity
. Oh well, there's still NoScript, AdBlock and OSS has a rather large list of sites to block.
Plus while I can't do something about all of them, I can at least do something about one of them.
BTW, getting back to Carnivore which links to Magic Lanternw
, there's a reason right there not to buy or use USA based anti-virus.
Instead, take advantage of the current Lifetime special on the Russian based Outpost Security Suite.
