I've used this for years, and it is awesome! Many times I've run into XSS causing malvertisements and such, they go down in flames!

I have gladly paid the developer for my use of this very handy and (IMO) essential tool. I think anybody with a conscience who decides to keep using it after they spend a week or two then decide to keep using it to pitch in a little bit, even if you an only afford five bucks. It's a gesture of respect, if nothing else.

A mouse click is enough to disable temporarily if it interferes with some website you enjoy.

Clearly one of my favorite extensions. I have had it for years and I really love it.

Extensão boa, mas por ser uma extensão recomendada no Firefox para Android a aparência da interface das configurações da mesma está fora da resolução de tela e sem quebra de linha no aplicativo e precisa melhorar a tradução do idioma pt-BR nas configurações e se possível adicione um submenu de escolha do idioma local do usuário na extensão.

The extension reveals my browsing history and I can't protect it from other PC users

I was so very happy using the previous version (5 star in my point of view), but latest resets itself every time I close Firefox rendering it undesired/not-needed on my pc's. I have to do every script acceptance over and over for every site I'm visiting ... so no good worth max 2 stars.

It takes a good while to set up your whitelist, but after that is done, this add-on feels as close to a must-have as it gets. Allows you unparalleled control over which parts of a page you allow and which not. This add-on should be the backbone of every security-minded user.
