In-depth safety analysis
This extension requests broad host permissions (*://*/*), meaning it can technically read and alter data on any website you visit. This is a standard requirement for user-agent switchers because they must modify outgoing network requests for all sites, but it grants a very high level of access. The use of declarativeNetRequest in Manifest V3 is a safer modern approach, as it allows request modification without necessarily inspecting all page content, though the host permission itself still allows broad potential access.
For extensions in the user-agent switcher category, a key safety consideration is that they become a single point of control over how your browser identifies itself to every website. A careful user should verify that the extension comes from a trusted developer, as a malicious or compromised switcher could not only change your fingerprint but also inject or redirect content. Given the publisher's limited established identity, extra caution is warranted.
This extension's strongest safety dimension is Maintenance & Ownership, indicating it is actively updated and well-maintained. Its weakest dimension is Permissions & Access, reflecting the broad scope of what the requested website access technically allows, even if it is necessary for the extension's function.

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.
