Is Blue Blocker safe?

Clean risk

Blocks or mutes selected Twitter/X accounts with paid blue checkmarks from timelines, replies, search, and user pages.

This extension scans major Twitter/X tweet locations and can block users with paid blue checkmarks in the background, with options to skip people you follow, followers, affiliates, or certain notable accounts. It provides settings for block speed, tab syncing, optional notifications with unblock controls, muting instead of blocking, and optional blocking of users with NFT avatars. The description says it uses your Twitter/X cookies and headers to block users through the Twitter/X API.
