Thanks for staying up-to date against new tracking/ads techniques!

Some people should stop overreacting about the IP and hostname permission request. Please inform yourself before reacting. Don't be a knucklehead. Here, let me do the homework for you:

https://github.com/gorhill/uBlock/wiki/Permissions#access-ip-address-and-hostname-information

5 stars rating for the uBlock team for staying very transparent about the permission requests.

Please don't give a one star rating when you don't understand why the addon asks for your IP and Hostname. Read the release notes before rating this addon. This is one of the best addons and it is open source - so you can have a look behind the scenes if you don't trust it.

In short:
The reason for the new IP and Hostname permission is to block more and advanced advertising:
https://github.com/gorhill/uBlock/releases/tag/1.25.0

Originally this review was one star after getting the "Access IP address and hostname information" notice with the latest update. However, I was not fully informed of what this meant nor educated on how the WebExtension JavaScript API is laid out.

According to the developer and my own research, uBlock Origin has no access to YOUR IP address. The extension is asking for permission to access the IP address of the website/server you are trying to connect to. The reason why you may have seen or may now see the "Access IP address and hostname information" notice is because, IRONICALLY, uBlock Origin required more information from the servers being accessed in order to block trackers which had found a technique to bypass the filters/rules that uBlock uses. In order to do so, this was only possible by allowing the extension to access server-side DNS information, which is what triggered the "Access IP address and hostname information" notice.

So, be rest assured that this extension has not sold itself to the devil! We still have a reliable extension being developed by those with our best intentions in mind.

Please see the links below if you would like to look into this further.

I gave a 1* but have changed it, its not Ray's fault, like others have mentioned do your research.

Good god people, read the release notes before you freak out. This is still as good as it gets. Raymond Hill isn't coming for your precious IP's...

Entendo que precisa dessa atualização, mas prefiro ir para outro bloqueador nesse caso!

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

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.
