I'm very satisfied with this extension. Default options right after installation are generally fine. If you want better results, It takes some time to learn about all the available options but the more you learn the more you'll benefit from this fast, light and very customizable extension.

Greetings. I am using this addon for some time, however since yesterday it has not been blocking ads. Cannot find a solution on the internet. I would be really happy if you could provide me some advice.

------------------
Thanks for reply. I also tried another addon, Privacy Badger and it seems that also does not work. Maybe something is wrong with Firefox.

-------------------

After reinstalling whole firefox with returning to default options and preferences it repaired.
Thanks for your time.

Sajnos újabban azt is letiltja, amit nem kellene. Remélem hamarosan rájönnek a hibára.
