Quick and easy to disable/enable JS.

A bit dissapointed, as the author stated he picked up "Javascript Control by Erwan Ameil" to change it's default behaviour (disabled). But he ended up leaving it disabled by default. So what's the point? I installed this expecting he would keep his word on his comment:
"by meetDeveloper, 6 years ago
I really liked this add-on apart from its default policy, so I forked the Code and edited to change the default policy, and made a new extension https://04.yfhome.xyz/en-US/firefox/addon/quick-js-switcher/ , feel free to install that. "

It doesn't show up in the toolbar or in a right click. There is no way to use the thing.

It is a very convenient addon that you can set the default status of script being "on" or "off".

is it possible disabled js by default

Android安装成功，也可以切换JS，但是地址栏图标在开和关时没有颜色变化。是否考虑更好地兼容Android？

Excellent extension.
Contrary to a lot of other extensions that disable JavaScript, this extension looks for <noscript>-tags and adds them to the DOM.
Without this looking for <noscript> you have no JavaScript AND no <noscript>-code. Now you have the best of two worlds.
Especially when you're building sites and you have to check if <noscript> works this is an excellent add-on.
Going every time to about:config or the settings in the developer tools is getting really annoying, simply clicking on an icon works far better.

Великолепно! Отключение и включение по 1 клику, большего и не надо.

Works well
