MultiHighlight

The extension has a very small user base of only 970 users, which limits community validation. The rating of 3.5 out of 5 stars from just 4 reviews suggests mixed user experiences, though the sample size is too small to draw strong conclusions. The lack of developer information and company details reduces transparency and accountability. However, the extension uses Manifest V3, which provides better security controls than older versions.

The primary concern is the limited user adoption and minimal review feedback, making it difficult to assess real-world performance and reliability. The activeTab permission, while appropriate for a highlighting tool, still allows access to sensitive page content when the extension is actively used. The absence of detailed developer information makes it harder to verify the extension's legitimacy and ongoing support.

Given the low risk level but limited trust indicators, consider testing this extension on non-sensitive websites first. Monitor its behavior during use to ensure it only highlights text as expected. If you frequently work with confidential information, consider using a separate Chrome profile for this extension. Keep an eye on future updates and user reviews to gauge ongoing development and community feedback. For critical work environments, you might want to seek more established alternatives with larger user bases and clearer developer credentials.
