No more YouTube comment stress. YTBM is a browser extension that blocks toxic comments and channels, removes Shorts, and filters keywords — so you can clean up YouTube exactly the way you want. You decide what gets blocked. ■ Features • Comment & Live Chat Blocking (All-in-One Account Block) — Blocking a comment author's account (channel) automatically blocks all of their other comments, uploaded videos, Shorts, and live chat across YouTube. A block button also appears next to nicknames in live chat. Replies are kept visible by default, but can be hidden via the Filter tab. • Hide Shorts — Completely removes Shorts from the Shorts tab, home feed, and search results with a single toggle. • Focus Mode (Hide Home Feed & Recommended Videos) — Prevent algorithm distractions by hiding the infinite recommended video grid on the YouTube home page and the related videos sidebar next to the video player. An intuitive guide banner is shown on the home page when the feed is hidden. • Hide All Comments & Chat — Hides all comment sections, Shorts comments, and live chat windows with a single toggle. Use this when you simply don't want to see any comments, regardless of channel blocking. • Channel Blocking — Block any channel from your feed, search, and comments. A block button appears instantly when you hover over any video. • Video Blocking — Hide specific videos without blocking the entire channel. • Instant Block & Undo — Enable 'Instant Block Mode' in settings to block without a confirmation dialog. Made a mistake? Click on any hidden comment to instantly restore (Undo) it. • Keyword Filtering — Automatically filters out comments and video titles containing words you specify. • Auto-Block on Keyword Match — Adds commenters whose comments contain specified keywords to your block list the moment they are detected. Can be toggled ON/OFF whenever needed. ⚠️ Read this before enabling Auto-Block on Keyword Match This feature does not understand context — it only checks whether a word is present, not its meaning or intent. If you add "idiot" as a keyword, someone writing "Wait, he's not an idiot — he's actually brilliant" will be immediately blocked and remain blocked until manually restored. The shorter and more common the word, the higher the chance of false positives. ⚠️ Please follow these guidelines: • Use long, specific phrases for keywords rather than short common words. • Check the auto-block log regularly and restore any wrongly blocked accounts. • Add trusted channels to the whitelist in advance. • False Positive Log & Bulk Restore — All auto-blocked entries (account name, keyword, comment text, timestamp) are recorded in a separate tab. Supports search, individual unblocking, and bulk restore by keyword. Restored accounts are automatically whitelisted to prevent re-blocking. • Whitelist — Register channels that should never be blocked. Whitelisted accounts are protected from all block conditions. • Backup & Restore — Export and import your block list as a JSON file. Switching browsers? Your data comes with you. • Performance Optimization (Prevent Comment Scroll Lag) — Click this if scrolling feels laggy after loading hundreds of comments. It frees memory and reduces lag by clearing read comment DOM nodes above the viewport without needing a page refresh (F5). (Scroll position is perfectly preserved after cleaning.) • Upgraded Settings & Options Layout — The popup UI is organized into a clean 'Filter | Block | Settings' layout, with the 'Settings' tab split into 'Options / Tools'. A new 'General Settings' tab is added in the options page to cleanly manage all Focus Mode and Block Action configurations inside card layouts. • Community Reputation — Displays a "⚠️ N blocked" badge on accounts reported by multiple users. Hover over the badge to see a breakdown of reports by reason. You can submit block reasons to contribute to the data, but you always decide whether to block. (Off by default, optional) ■ Who is this for? People tired of toxic comments and spam / Anyone who wants to completely remove Shorts from their feed / Users who want to firmly filter specific channels or keywords / Those who want to block spam bots at the source / Users who want to combine keyword filtering with account blocking / Anyone worried about false positives / Those who want to manage their filters with logs and restore tools ■ Privacy All block data is stored locally in your browser and never sent to any server. The Community Reputation feature is OFF by default. If enabled, only fully anonymized data is processed — no personal information is collected. ■ Support & Bug Reports For feature requests or bug reports, please contact no7beckham.dev@gmail.com --------------------------------------------------------------------------------------------------------------------------------------------- Patch Notes v2.1.9 -Fixed false positives in Korean mentions. -Fixed a bug where configuration data was loaded twice on popup open, and cleaned up leftover empty comments v2.1.8 -Blocked channels no longer bypass filters during lazy-loading on Home Feed. -Automatically syncs handles to name-only blocks without duplicate data, ensuring clean unblocking. -Fixed a bug where the 30-second block buffer banner persisted on recycled comments while scrolling YouTube Shorts. -Removed Lab Log height limit & added search bar. -Added descriptions explaining that logs are only recorded when the auto-block option is active. -Increased options page font sizes for readability v2.1.7 -New 'Focus Mode' Hide Home Recommendations: Hides video recommendations on the Home screen Hide Watch Recommendations: Hides the recommended video sidebar on the watch page -Fixed an issue where clicking the block button during the 30-second auto-block banner would delay the block overlay until the timer expired.
