I am using Edge. I don't see any discount coupons. I must have clicked a "no ads pls" buttons somewhere, but now it's good.
Speaking of adware and spyware, doesn't Firefox still have Google as its default search website? They are not Google, but literally selling you to Google, that's like even worse?
It takes more than one click just to get to the right settings page, and there are numerous anti-features scattered across several settings pages. Cleaning up Edge is way more than one click.
