Is Highlighty: Search, Find, Multi Highlight Safe? — Extension Safety Profile

This extension requests broad host permissions for all websites and local files, which allows it to read and modify content on any page you open. That scope is typical for a highlighting tool that needs to scan text across different sites, but the inclusion of file:// access means it could also interact with local files viewed in the browser. The developer’s privacy disclosures state that the extension collects personally identifiable information, financial and payment data, authentication details, personal communications, and web history — a range far beyond what most simple highlighters require.

For any browser extension with wide content access, a careful user should consider that it can technically see everything you type or view on matching pages. General safety advice for this category includes reviewing why an extension needs such permissions and checking whether its stated data collection aligns with its function. The declared collection of sensitive categories like payment and authentication information is unusual for a search-and-highlight utility, so it is worth verifying the developer’s privacy policy to understand how that data is handled.

The fact sheet shows a strong Maintenance & Ownership score, meaning the extension is actively updated and its ownership is clear, which helps with timely security fixes. The weakest dimension is Publisher & Identity, indicating limited transparency about the company behind it. This combination suggests that while the code is maintained, users have less public information to assess the developer’s track record, making it prudent to weigh the convenience of the tool against the privacy trade-offs.
