Summary

Introduction This web extension lets an user decide if JavaScript should be enabled or disabled for a given host or a given tab.

Features

  • Set the default state (JS on or JS off)
  • Set the disable behavior (By domain or by tab)
  • Use shortcuts (you can also disable this)
  • Use a context menu item for toggling (you can also disable this)
  • See your blacklisted/whitelisted domain list
  • Add domains manually before visiting a site
  • Add base domains that automatically enable/disable JS for sub domains
Usage When accessing e.g. mozilla.org and disabling JavaScript, the web extension will block all JavaScript which otherwise would be loaded by mozilla.org (including inline JS and external JS files from other hosts).

Please note that scripts from the blacklisted host will still be loaded if they're being loaded in another host (unless you block that host as well of course).

Supported browsers

Why to use this web extension The code is completely open source, you can also use the unpacked version of this web extension if you prefer. No data of you will ever be logged and the web extension asks only for the permissions it really needs.

ドメイン指定でJavaScriptを無効化出来る便利なアドオンです（☆5）、が…… 同名のChromeアドオンのバージョン2.3.2がマルウェア認定され削除されました（☆1）。 「2.3.1 / 更新日 2018年12月11日」 「2.3.2 / 更新日 2024年3月10日」 とのこと。更新が来ていますがご注意ください。 先日は「2.3.2 / 更新日 18日前 (2024年3月10日)」でしたが変わりました？ GitHubのissueではこの件について話されてます(/issues/118)がFacebookとLinkedin絡みですかね。

This was a 5 STAR addon up to & inclusive of version 2.3.1 but the addon was sold. None of the description is accurate. 2.3.2 is not by the same author, is not on github, no posted privacy policy, has been minified, contains MALWARE per Google & MSFT. DO NOT LET THIS ADDON UPDATE TO 2.3.2.

Usefull add-on, but your Chrome extension got removed as malware. This doesn't need to effect this add-on, but do you want to explain what's going on?
