It is possible to implement an add-on that disables and enables Javascript without reloading the page? Thanks in advance for your answer.

it is so nice

This is a very important add-on nowadays.

Finally a plugin to restore some pre-quantum functionality.
Thank you!

very useful, simple, easy. Perfect.

awesome. Does just what it needs to do and nothing more.

Very useful n easy!

Similar to Quick Javascript Switcher for Chrome. Very elegant in its design and function. Open source! Works beautifully.

Спасибо!

Very very useful, can't believe Firefox is missing such a basic feature as JavaScript disable button.

A decent competitor and alternative to noscript. However it causes layout issues on some sites, like duckduckgo and startpage. E.g the text "The search engine that doesn't track you. Learn more" appears twice. This is with JS enabled. It's also a consistent issue, but if you refresh it disappears. Haven't found other websites with similar issues, I'm sure there are more.

Edit: Might the "google goes blank whenever a link is opened" issue on github be related to this? I don't know
And whenever you click on a link in duckduckgo it says "You are being redirected to the non-javascript version of the site". Excuse me, but I have it enabled! It doesn't actually do it, it's just a message.

A brilliant add-on, simple to setup and use, and did exactly what I was hoping it to do: automatically disable JavaScript on sites unless the domain I specify is listed (called whitelist in this case). You can also allow subdomains per each listed domain so it will work across an entire site. Alternatively you can set the default behavior to work vice versa and always allow JavaScript to work on all sites unless a domain you specify is listed (called a blacklist in this case). Some nitpicks I have (by which I think these functions or abilities would be nice to have but don't hinder functionality currently) are:

Ability to backup and import domain lists within the options.
Support for containers.
An option for a "grey list", or ability to allow JS for the current session/tab/domain but disable again when the browser is closed without need to modify the white/blacklist.

Overall, a great Firefox extension, I highly recommend giving it a try.

very useful !
keep on good work. ;D

Great addon.

works perfectly

Muito bom! Simples e prático.
