Development build
NoScript development happens very fast to keep up with emerging web threats. 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 candidate.
RC for Firefox
Install NoScript 13.2.1.901 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.
Non-store versions for Chromium
On Chromium based browsers you can download either:
- NoScript 13.2.1.901 (MV3) - experimental, supporting the Google-mandated but limiting, unproven and unstable latest extensions technology. Requires Chromium version 128 or above (latest stable version recommended).
- NoScript 11.4.44 (MV2) - legacy, unsupported by Google but proven and stable. Best option for browsers based on Chromium 127 and below.
In order to install next MV3 version until it reaches the Chrome Store, or the MV2 version if you're affected by some MV3-caused bug which could not have been fixed yet, you need to unzip the downloaded noscript-$VERSION-chrome.zip file and load its content as an unpacked extension in developer mode.
Please follow these steps:
- 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
- Enable Developer Mode by clicking the toggle switch next to Developer mode.
- Unzip the zipped "noscript-13.2.1.901-chrome.zip" package to a directory of your choice.
- 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 13.2.1 is compatible with browsers based on Gecko versions 115 and above (e.g. Firefox and Tor Browser, on desktop and Android) and on Chromium versions 128 and above (Chrome, Edge, Vivaldi, Brave...)
NoScript 11.4.44rc2 is compatible with Gecko versions 59-114.
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,
- latest NoScript version compatible with Gecko 57 - Gecko 58 is 10.1.7.3;
- latest NoScript version compatible with Gecko 46 - Gecko 56 is 5.1.9 (SHA256);
- latest NoScript version compatible with Gecko 13 - Gecko 45 is 2.9.0.14 (SHA256);
- latest NoScript version compatible with Gecko 1.9 - Gecko 12 is 2.9.0.1rc1 (SHA256);
- latest NoScript version compatible with Gecko < 1.9 is 1.10 (SHA256).
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.
