Development build

NoScript development happens very fast to keep up with emerging web threats. Each published development build in-between stable releases is considered a release candidate and is marked by a version number ending with 90x, e.g. 13.6.2.901.

If you're brave enough and you need a specific feature or fix not released yet, or you simply want to provide feedback before official release, you may want to try the latest release as listed below.

RC for Firefox

Install NoScript 13.6.2.901 on Firefox Desktop by simply clicking here.

On Firefox for Android, unfortunately, a pre-release can only be downloaded (same link as above) and temporarily installed on Nightly by using the web-ext tool, which is only suitable for hardcore developers and contributors.

RC for Chromium

Download NoScript 13.6.2.901 (MV3 for browsers based on Chromium 128 or above).

In order to install non-store extensions like NoScript 13.6.2.901 on Chromium-based browsers you need to unzip the downloaded noscript-$VERSION-chrome.zip file and load its content as an unpacked extension in developer mode.

You can install an unpacked extension on Chromium by following these steps:

  1. Open the Extension Management page by navigating to chrome://extensions. Alternatively, open this page by clicking on the Extensions menu button and selecting Manage Extensions at the bottom of the menu. Alternatively, open this page by clicking on the Chrome menu, hovering over More Tools then selecting Extensions
  2. Enable Developer Mode by clicking the toggle switch next to Developer mode.
  3. Unzip the zipped "noscript-13.6.2.901-chrome.zip" package to a directory of your choice.
  4. Click the [Load unpacked] button and select the extension directory you've unzipped the extension to (the one containing the "manifest.json" file)

You're done. Happy testing!

Browser compatibility and obsolete versions

NoScript Classic Logo

You can still download NoScript "Classic" (5.1.9) (SHA256) for Seamonkey, Palemoon, Waterfox Classic and possibly other "vintage" (pre-Gecko 57) Firefox forks here.

Notice: you may need to open about:config and set your xpinstall.signatures.required preference to false in order to install NoScript 5.x, since Mozilla doesn't support signatures for legacy add-ons anymore. If you're using a non ESR Firefox, you may also need this hack.

Users of Firefox 58 and below are urged to upgrade their very unsafe browser. For those few who can't,

Disclaimer We cannot update nor support NoScript 5.x and below anymore, because it was based on a completely different and now obsolete technology. However you can still find usage information and a FAQ section for those ancient versions in the NoScript Classic archived website.
