Is DeepSeek Open SideBar in Chrome safe?

Low risk

DeepSeek Open SideBar in Chrome removes anti-framing and content-security headers on DeepSeek and Google pages.

The extension installs a declarative network rule that removes X-Frame-Options and clears Content-Security-Policy response headers. This applies to DeepSeek and Google pages covered by its host permissions, including navigations and subresources while the extension is installed.
