That's why I don't use any such tools and I'm extremely careful when I approved the few extensions from verified sources I use in the browser. But I am fully aware of the supply chain attacks so Grammarly, for example, and 1Password could also potentially inject malware.
But tools like Greasemonkey and Tampermonkey are the good guys. They tell you when scripts are updated, etc.... Malware versions of comparable tools could operate entirely below the surface, without your ever knowing.
