Review summary

Users praise Script Blocker Ultimate for being easy to use and lightweight, with effective, early blocking of scripts (including autoplay) and flexible white/blacklisting. It’s viewed as a simpler alternative to NoScript and privacy-friendly. However, common criticisms include the lack of logs and poor visibility of blocked/allowed URLs, plus requests for more granular controls (per-link rules, regex support). Some reviewers also want more proof of the claimed no-tracking behavior.
Pros
  • Easy to use and lightweight; designed to be simpler than NoScript.
  • Blocks scripts early in the page load, reducing script activity and improving page performance.
  • Flexible black/white lists with wildcard support for precise control.
  • Privacy-friendly operation with claims of not tracking user activity.
  • Effectively blocks intrusive scripts such as autoplay and random in-page scripts.
Cons
  • No built-in logs or a visible list of blocked/allowed domains, making auditing difficult.
  • Limited visibility of what will be allowed when whitelisting; it’s hard to quickly see which URLs are blocked or allowed.
  • Users frequently request more controls (per-link enable/disable, per-domain rules) and features like regex support, which are currently missing.
  • Some reviewers are skeptical about the privacy claims and would like verifiable proof of not tracking user activity.

2025-12-17 bo***** I like this Add-on, it's easier to use than NoScript, and seems to block sooner in the add-on chain, relieving work on privacy screens and such, and it catches non-existant domain names from running scripts. (which is a particular problem I've been having lately … random invented domains which seem to run directly in memory without going out to the router) @developers, I would like to use it *instead of* NoScript, but sadly I need to keep NoScript, because that lists the domains it blocked and allowed. I need that list to know what to add to the blacklist, and I don't get, even a log, from Script Blocker Ultimate. So I only know I've got my blacklist right for current threats because they don't show up in the NoScript list any more.
