JS Blocker Ultimate

Block JavaScript on any site. Four modes, whitelist and blacklist with wildcards, per-site controls and stats. Free, no tracking.

JS Blocker Ultimate makes it easy to block JavaScript, for a cleaner, faster and safer web. Everything is free: no account, no limits, no locked features. One toggle, four modes: - Allow all: allow all scripts to execute. - Block all: block all scripts to execute. Be careful, sites that need JavaScript will not work properly. - Block all but whitelist: block all scripts except those in your whitelist. - Allow all but blacklist: allow all scripts except those in your blacklist. A good fit for news sites full of ads, where only the text matters. More control than a simple on/off switch: - Current-site card: see whether this site is blocked right now and fix it in one click with Allow site, Block site, or Temp allow. - Temporary session rules: let a broken site run scripts for this browser session only; the rule clears itself when the browser closes. - Whitelist and blacklist with wildcard domains: an entry like google.com covers its subdomains too, and *.google.com works the way you expect. Paste a full URL and it is tidied into a domain. - Search inside your lists on the full settings page. - Right-click menu: allow, block or temp-allow the site you are on. - Keyboard shortcut (Ctrl+Shift+B) pauses or resumes blocking. - Toolbar badge: a red X marks pages where scripts are blocked. - Stats: pages protected since you installed, kept locally. - Backup: export and import your settings as a JSON file. While blocking JavaScript you might encounter some irregular behavior in web pages, which can usually be solved by whitelisting that page. Private by design: JS Blocker Ultimate injects nothing into pages and reads no page content. Your settings and stats live in your browser's local storage. No uploads, no tracking, no server. Happy blocking!
