In-depth safety analysis
The permissions it requests are standard for a highlighting tool that works across pages. tabs lets it know which URL is active so it can apply your word lists, contextMenus and notifications provide convenient interaction and alerts, storage saves your settings locally, and alarms/offscreen handle background timing and Manifest V3 requirements. This access is normal and expected for its category.
A general risk with any extension that reads and modifies page content is that it can see everything on the pages where it runs. Highlighters need that ability, but a careful user should avoid enabling them on sensitive sites like banking or webmail and should prefer extensions from well‑known publishers. Since the developer self‑declares that data is not sold or misused, the privacy posture appears sound.
Our assessment shows a strong Maintenance & Ownership score (100%), indicating the extension is actively updated and ownership is clear, which is a positive sign for ongoing reliability. The weakest dimension, Publisher & Identity (60%), suggests the developer’s background is less established or transparent. This does not imply a problem, but users who prioritize a widely recognized publisher may want to look into highlightthis.net independently.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
