In-depth safety analysis

This extension requests the "webRequest" permission along with host access to all HTTP and HTTPS websites. In practice, that combination allows it to read and modify every network request your browser makes, including the full URLs and any data sent or received. For a tool that displays HTTP headers, this level of access is technically necessary to inspect the traffic, but it is also extremely broad and sensitive.

General browser extensions in this category can pose risks if they are not kept up to date. A careful user should be aware that an abandoned or infrequently maintained extension with such powerful permissions could become a liability if browser APIs change or if security vulnerabilities are discovered over time. The fact sheet shows the extension was last updated in late 2021, which is worth noting.

The strongest dimension in the fact sheet is Community Reputation, reflecting a solid user rating and a reasonable number of users relative to the store listing. The weakest dimension is Maintenance & Ownership, which indicates a lack of recent updates and limited signals about the publisher's long-term commitment. This contrast between user satisfaction and ongoing upkeep is the key point for a user to weigh.

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.

Who's Behind HTTP Headers?

  • Publisher Christopher Kalafarski

Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
