It's not lost on the legal world that no one reads Terms of Service. As a result, TOS are rarely enforceable in court, except inasmuch as they comply with broad industry standards.
However, compliance requirements are much MORE strict for parties who demonstrably should be aware of their legal obligations. Lawyers, for example, can't really argue that they didn't read a legal document they executed because of the manner in which it was delivered (in an inscrutable TOS doc, at the entrance to an amusement park, etc).
If you install this extension, you might actually be making yourself MORE bound to crappy terms of service, since you will not be able to make the case that obviously you didn't read them terms and therefore should not be held to some non-standard provision.
The reviews/ratings provided by tosdr.org are awesome, and I hope you guys continue this project, but I, for one, will be covering my ass and not installing this extension.
