DoNotTrackMe............Oh except you guys are. Rated 1 out of 5 stars

Was happy until....January 2014...I was making an online purchase and tried to enter my Email address.
Then some crap popped up saying Mask my Email.
I had to dismiss it (I want them to have my real email)
Seconds later I get stupid email from "Abine [Masked]" Welcoming me to DNTM
and saying "This email is forwarded from a MASKED EMAIL you created using MaskMe"

So it turns out that you guys are watching my online purchases--CREEPY
Felt like I'd been hacked. Your email beat my order confirmation by 7 minutes.

You should make the following changes:
If you add features, turn them off by default. (When I first installed, there was no MaskMe feature)
Turn off DNTM completely on HTTPS sites, clearly you have no business there.

Sorry had to uninstall because of this episode.

This review is for a previous version of the add-on (3.1.1038.1-signed). 

hi Mandy_Says,
sorry you didn't like the Masked Email feature. you can turn it off with one click in settings. Many users prefer not to disclose their email to other sites, so we provide this feature free. click settings to turn it off.
your suggestion to turn it off by default will be put to a vote of all free users who want to respond. your suggestion to disable on https sites would make one of the biggest ways you're tracked - via shopping, able to collect, track, and sell your profile very easily, so that would be bad for privacy.
