LinkedIn Muter

A lightweight browser extension to reclaim your LinkedIn feed by automatically hiding posts that match keywords or regex patterns you define.

Features

• Keyword & Regex Filtering: Filter posts by plain keywords or full regular expressions.
• Per-Rule Hit Counts: Each rule shows how many posts it has muted.
• Click-to-Reveal: In reveal mode, click a blurred post to temporarily show it.
• Sponsored Post Muting: Optionally mute all sponsored/promoted posts.
• Two Muting Modes: Completely hide posts (display: none) or blur/grayscale them so you know something was filtered.
• Infinite Scroll Support: Uses MutationObserver to filter new posts in real-time as you scroll.
• Dynamic Updates: Changes take effect immediately — no page refresh needed.
• Persistent Storage: Settings and keyword list are saved across sessions via the Chrome Storage API.
