Кусок говна! И без этой хрени можно во всем браузере выключить java!!

This isn't the add-on I attached, but magically, this is the one I now mysteriously have. I haven't noticed a toggle switch yet either in the browser or in device notifications. I am using an Amazon Fire Tablet running FireOS. Does this app work on Android?

5* app, but broken with FF 75.0 on Win7. Please update!

As of 1/30 this add on appears to hijack links. When clicking links a new tab opens a page on 'iyfsearch.com'.

OBVIOUS malware.
You don't need those permissions to turn a settings flag on/off.

I had this add-on installed, but after a while any page containing javascript was prevented from loading, irrespective the settings in of the add-on: I've uninstalled the add-on and any page loads again.

Aún no la tengo porque no sé cómo instalarla.

O firefox estava travando para entrar em vários sites, incluindo o do gmail, e descobri que era por causa dessa extensão, pois, ao desabilitar ela, o firefox parou de travar instantaneamente.

Doesn't work for me. Only sporadically.

This add-on does not behave well on my Note 3. The toggle icon went away after I toggled off Java and I could not toggle it back on. I uninstalled and Java was still blocked, so i reinstalled it and found the toggle options in the drop down options in Firefox 57. I 'enabled' Java, but it was still being blocked. I finally had to uninstall Firefox and reinstall it to enable Java to run. Needs some further development before I could recommend.
