Signed up specifically to leave this review after seeing the nonsense 1 star reviews in response to permissions prompt from the latest update. Per the other comments, READ THE RELEASE NOTES.

This is a fantastic add-on and Raymond Hill is an absolute champion. This project refuses donations and instead urges users wishing to offer their support to donate instead to the maintainers of open source filter lists, contrast this with say Adblock Plus and its "Acceptable ads" program which involves charging large institutions fees to whitelist their advertising.

Don't be a muppet and post knee-jerk 1-star reviews for an app which has done so much to keep the internet USABLE for so many of us. Do your research.

Still a great add-on. Regarding the recent update requiring IP and hostname permissions, see the dev's official statement on this below:

"Firefox 60+

uBO requires a new permission, dns, which is required to solve issue 780. This may triggers a new permission warning from Firefox when uBO updates to the latest dev build, specifically 'Access IP address and hostname information', even though this was already possible for uBO to access that information (through the webRequest API)"

Source: https://github.com/gorhill/uBlock/releases/tag/1.25.0

The reason for the new 'dns' permission is to block more advanced advertising mechanism:

it's alright

Hey, uBO requires new permission, but I won't check what's it's for on the main plugin page in "release notes" section. I'll use the feedback form on the same page and give this plugin 1 star with question what the new permission is for. Me is genius.

Greatly appreciate the work done on this addon. Thank you so much.

Än så länge väldigt effektivt bra skydd allt i ett koncept
