Thanks for your feedback.

Since the first version of this add-on, we also block tracking domains like doubleclick.net. Rules for these sites are not rational, because the entire page is a tracking "field".
This is the reason why we do not and will never delete complete domain blocking for tracking domains like doubleclick.net.
We also describe this feature since the first version in the description of the add-on, so every knows, what the add-on does.

Thank you for your positive feedback.

Edit: Since your review, I have made many performance optimizations on ClearURLs, especially for Android.
Can you reassess how ClearURLs is now behaving on your device?
