Useful, fast, simple to use, simple to add new clauses. Basically perfect.

No uBO No Web

Perfect. Never had any issues, always blocks ads. Intuitive design, blocks you from entering malicious sites (which you can turn off or enter anyway if you please) and allows for whitelisting certain sites. All in all, perfect.

einfach zu bedienen und sehr effektiv

Very happy with this adblocker. Installed it and never looked back. Blocks ads without the need to intervene. Extensive options. Thanks to the developer. Keep up the good work!!

Great addblock. Best out there. It's completely free/libre.

Starting to become obsolete. Popular and progressive websites are getting smarter and their ad spaces are nullifying uBlock's element blocker. You can zap countless times and the same add will reappear on every refresh. :(

Recently I can see more and more websites with ads which uBlock fails to block. There are websites that detect uBlock easily and block their content unless I switch it off. Another drawback is that it is sometimes impossible to pick elements for blocking on certain websites with no error message displayed (I consider this a bug). I think it's time to look for other ads blocking software...
