Overall sentiment is strongly negative: reviewers accuse Stylish of spyware and data collection, complain that the style site is broken and inaccessible, and note the extension often doesn’t function. Several reviews advise switching to Stylus as a safer alternative. A minority mention the ability to apply themes as a potential positive, but reliability and privacy concerns dominate.

The extension is reported as not working or dead on Firefox by several users.
Stylus is repeatedly recommended as a safer, more reliable alternative.
