Seems to work well and I changed the xpi to zip, looked over the code, and it seemed clean to me! I disabled auto updates for the extension just in case, because clearly the extension's original repository is dead. Also the fact that there's "resigned" in the file name is not a good sign, but, again, the code looks fine!! I wish these reviews about malware would specify in what file(s) and on what line(s) is the malicious code. I use this addon with noscript cause it adds a simple switch that I can put on the taskbar and it can just simply disable a single tab's js temporarily (until tab is closed). Which is nice when I don't want to completely unload the tab or block the associated sites or anything like that. I just want it to stop executing it's code temporarily. Also, Author; Please migrate your codebase to somewhere. Dude your github repo is gone obviously and even the web archive containing a copy of your github repo/issues just doesn't exist anymore.

***!!!Contains MALWARE!!!*** would give it one star but then it wouldn't show up at the top

How to enable it for all websites?

This extension was working great but at some point I could no longer access sites that used cloudflare protection with this extension enabled. Obviously it wouldn't work without JavaScript but even after enabling JS on the site in question, it would still fail. Hopefully issue gets fixed.

Offline pages (file:/// ...) do not appear to be considered by the extension.

I wish though to test my own pages under both conditions – with and without Java-Script – before I publish them. It is still not clear to me if this is a bug or just something that the author chose to do this way.
Please read the recommendation given by Didjo, further below. Dev tools is really all you need.

Contains malware – see web.archive for github/dpacassi/disable-javascript/issues/118

To easily disable / enable JS on a page in Firefox :
Open Dev tools (F12 / ⌘⌥I) → Debugger → Cog icon → Disable JS

Contains malware (see other comments)

I can't see a button. I tried deleting some buttons from my tool bar to free up space but I still can't see it. I also tried ALT Shift 1 but I did not notice anything happening. The extension is on and I restarted firefox. Seeing the reviews, I am removing it.

Support link no longer exists, archive from other user suggests this has in fact been transferred/sold onto other parties.

I noticed it wasn't working for me today anymore for some reason so I'm removing it.

I would suggest to exercise extreme caution if you intend to use this addon.

Its very helpfull for speciphic sites

Contains malware and breaks normal browser behaviors since 2.6.2

Contains malware. See this: [https:]//web[.]archive[.]org/web/20240329145533/[https:]//github[.]com/dpacassi/disable-javascript/issues/118 (remove [ and ] from link]).

Good, but not as great as it could be:

The keyboard shortcut clashes with other add-ons, and cannot be changed

If a site uses JavaScript to disable the context menu, then the context menu cannot be used to turn JavaScript off

This extension is using the code based on a discontinued github repository, which can be found here: github, user: dpacassi, Repository: disable-javascript

This current extension version contains malware, which can be learned about here:
github, user: dpacassi, Repository: disable-javascript, Issue # 118.

fantastic! finally something that just works and is what i asked for, perfect for testing noscript tags and just disabling js for one page you are currently on

I love this add-on.

very useful
