How can I turn off data sending?

I am still experiencing ads poping onto my screen.

Убивает кэшбэк. Несколько раз вносил в исключения-бесполезно. Или себе забирает или просто убивает.
Господа разработчики, может вам этот момент лучше продумать, хотя если вы воруете кэшбэк то вопрос снимается...

It's horrible. It blocks not only advertising but also the main elements of many sites. For example, it's impossible to work with send.firefox.com and make payments on privat24.ua.

Horrible. Blocking key sites I need to access while allowing one's I don't want. Great perhaps for geeks. Appeared with last Firefox update but no explanation on how to white list sites you don't want screwed up. Once I blew an hour searching/viewing YouTube for how too's it seems to work. Would be nice if uBlock provided simple videos on how to use it.

New permission "Store unlimited amount of client-side data". makeit 10-20 not unlimited ...im not updating .

Ne fonctionne pas, la sauvegarde dans un fichier donne un fichier vide avec plein de lignes.... vides
Bravo pour proposer des extensions non fonctionnelles c'est beau :)
