Is Block Ctrl W safe?

Low risk

Block Ctrl W lets any website query its content script and receive an active-extension status response.

Block Ctrl W injects a content script on every website and listens for page message events. If a page sends JSON with the action QUERY_BLOCKCTRLW_STATUS, the content script posts back a BLOCK_CTRL_W active status; no external recipient is shown in the reviewed code.
