It only blocks scripts and only external scripts. It doesn't actually disable JS. So, NOSCRIPT HTML tags won't work.

Easy to use for a Firefox fancier.
U can JS on/off so quickly.
Simple <3

This is a great add-on. It has become an essential tool that has really optimized my browsing experience. Recommend pinning icon to toolbar for quick toggling on/off as needed.

Отлично, а главное - есть кнопка.

Excellent! I've been wanting this toggle control in firefox for a long time now. A sorely missing control. My primary browser is firefox, but I sometimes switch to safari when I want to stop javascript on a particular webpage. This toggle button addon bascially does the same thing here that safari does in it's preferences -> security pane. Plus the addition that it automatically reloads the page for you. (It also has a preference setting to let you control auto-reloading in both directions.) It's even worth a small donation! (but it's not clear I can set the amount?)

Muito bom, em sites que necessita do JAVA simplesmente ele ativa e se quiser desligo num clique, se você está procurando aitvar o Java para jogar, ver animações ou escutar musica em sites que usa java , use esse aplicativo , ele usa o webextensao java, uma alternativa sem complicação e instalação do java.

El más simple... el ícono es muy claro!

just works

Does what it promises, but the toolbar switch disables JS globally (on all sites) until you enable it again. Usually I just want to disable it on one specific site, temporarily or permanently. In the addon settings there are options to white- and blacklist sites, but I wish there was a shortcut for this.

Excelente complemento!

This little magical button belongs right on the side of your URL bar. Honestly, it should be built in as standard on 100% of Browsers.

--Then everyone can actively interact with JavaScript and stop being dictated by others. There is a 100% chance that JavaScript is currently interacting with everyone already, whether they know it or not!! So why not put the power back in your hands?

Imagine yourself on a lazy Sunday afternoon, quietly reading an article about meditation... when BAM!!! All of a sudden this OBNOXIOUS, bright-red, completely unnecessary pop-up window instantly COVERS your screen.
Now stay calm. This is the right time to just take a deep breath. Feel free to shake your head slowly in righteous moral superiority,towards this blatantly uninvited, rude behavior. For now it is time yet again to casually slide your cursor up onto the right-side of your address bar. *Click!* Oh the magic little button. What a relief. Life is right back to what you were previously occupied doing.

At that moment, you can have this additional satirical moment acting out as the stern, a-bit-too-mean-but-fair second grade teacher actively scolding this particular immature and annoying web designer:
"Sorry Timmy, but for today you have lost your ability to use JavaScript. We're not going to act out like that, anymore; okay bud? Tomorrow I'll think about maybe giving your privileges back, but as for now... they're 100% gone.
So now go sit in the corner, so the rest of us can get back to what's actually important."

Sick of bouncing banners and those damned videos that keep popping up when you scroll down? Tired of pop-ups wanting you to register in order to read an article? This thing hasn't failed me yet. It knocks out some web page features, but cuts out all the annoying crap.

Good really
