Intercepting fraud phone

Sounds fishy to me, it is most likely to be a chinese extension that is going to make money with your browsing profile.

I cant say for now that it is dangerous but I would advise some caution while testing this one.

I would rather use MalwareBytes extension with uBlock Origin anyway ...
