Is SideAll: Chat Sidebar - GPT, Claude, DeepSeek safe?

Low risk

SideAll modifies DeepSeek response headers so DeepSeek pages can be framed with fewer browser protections.

When the extension is installed or Chrome starts, it registers a declarativeNetRequest rule for DeepSeek frame loads. The rule removes frame-protection and content-security headers from deepseek.com responses and sets Access-Control-Allow-Origin to *, and it is not limited to only the extension's own sidebar.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
