1-Click Blocker for X/Twitter par Sleepy-A

1-Click Blocker for X/Twitter adds a one-click block (or mute) button right inside every tweet, on profile headers and on follower lists, so you can clean up your timeline instantly — no more opening the "···" menu and digging through submenus.

The button blends into X's own action bar (a prohibited-sign icon for block, a muted-speaker icon for mute) and turns green when done. Accounts you have already handled are marked automatically, so you never act twice.

KEY FEATURES

• One-click block / mute on every tweet, on profile pages (right next to Follow) and on user lists (followers, following, people search).
• Instant feedback: the blocked account's posts vanish from the page the moment you click — no reload needed.
• Choose your default action (block or mute) and switch it any time from the toolbar popup — open X tabs update live.
• Per-surface control: decide exactly where the button appears (timeline & communities, replies & mentions, profiles, user lists, search & explore).
• Bulk blocking queue: paste a list of handles — or import a CSV / JSON / TXT file — and let it run in the background with smart throttling so you don't hit X's rate limits. Live progress, automatic pause + desktop notification if X starts limiting, one-click retry of failed handles, and a run history.
• List management: a searchable log of everyone you've blocked or muted, with Undo on X (unblock/unmute), Remove, and Export to CSV.
• Backup & restore all your lists and settings as a JSON file.
• Reliable: if X's API ever changes, the button falls back to clicking the native menu automatically.
• Multi-language interface with a built-in selector: English, Spanish and Portuguese (auto-detects your browser language).

PRIVACY & SECURITY FIRST

• No tracking, no analytics, no third parties. Everything stays on your device using local browser storage.
• Minimal permissions: storage, notifications, and access to x.com / twitter.com only.
• No remote code: no external scripts, no eval. The only network requests go to X's own API to perform the blocks and mutes you ask for.
