1. Dont see any blacklist ... in the code, but i might have mised it.

2. Seems to only for miners from CoinHive, Mineralt and Webminerpool and "only" tries to invoke their "stop()" functions. (fine i guess)

3. Addon is quite old and outdated (3 years) so there is a high probability it does not even work anymore.

4. From a programmers perspective i also find the code a bit laking in clearness. Maybe involuntary? -

Overall, seems safe to use with a good idea behind it, but could maybe be improved even more.

makes Firefox slower. features are slow, difficult to use; parts of sites do not load or appear wrong. REPORTED.

do not block pirate bay

Hasn't been updated in a while (which is worrying), but it still works 99% of the time pretty much flawlessly.

cumple lo que promete, me ha ayudado a bloquear minado de paginas que con otros no logro bloquear

Excellent.

Test your minerBlock at this Website URL ... https://cryptojackingtest.com/

About two days after I installed this add-on, today suddenly my computer started freezing time and again, freezing so much I had to shut him down by unplugging the power cable!
I started to examine everything, hardware, software and it showed that Firefox was the culprit!
As nothing else was different or new or updated than the days before, I concluded, minerBlock must have done that freezing.
I deleted it and - oh wonder - Firefox works fine again.

Excelente funciona bien.

If you can add support for mobiles, you will make this extension more useful.

Thank you so lot that you always working on it!! (I like to reading here your support!)
Great Developer (y) ;)
Some of the other developer quits some time later :( So i want share my respect for your working time!
Best wishes for you future & greetings from Germany :)

Nunca eh visto que llegara a bloquar algo mientras estoy navegando, pero al leer los comentarios de los demas usuarios (se ingles) le doy su punto de confianza a la extensión ya que no veo el uso de bots para "tener mejor presentación" a diferencia de otra extensión que solo tiene 3 reseñas y más de 500mil usuarios. Si no sabes que es te explico, es una extensión para el navegador que protege tú PC de cierto malware que se dedica a "crear" dinero digital que no solo hace lento el computador sino que tambien te lo puede dañar. Felicidades al desarrollador.

A must tool for protecting oneself in the Internet. But there must be something wrong with the widget, the settings button cannot be clicked.
