Impressive, but still needs some additional features

I am very impressed with this Safari extension. However, I would love to see two additional features: 1) the ability for the user to disable javascript on specific sites and 2) the ability for the user to add to a personalized filter list (i.e., allow the user to block content from specific sites; the functional opposite of the current "Whitelist"). Thank you for your continued work on this app/extension and making it open source!

Tricky to setup at first, but seems to work okay.

I used the previous ublock origin obtained through the extensions gallery and found that it worked well. I have read all the negative reviews for "new" ublock through the app store and was hesitant to download it. It's a little unintuitive to setup--you have to download it, go the Safari extensions settings to turn both the app and the icon on, and THEN open the app and update the filter lists to get it to work properly. This process should really be streamlined so it's ready to work from the get-go. It also installs a stand-alone app, which doesn't make me super happy, but I'm wondering if it's a OS X requirement.

Installs & Works Great

I read all the reviews saying the new uBlock does not install or work. Yes it does, you just need to follow the install instructions. For Safari 12 it is both a Safari Extension and a desktop application. Both must be properly installed and running. I've been using some ad heavy websites, they load much faster with no ads.

Subtracted one star - In MacOS Mojave if you are using Dark Mode the text on the buttons that appear when you click the uBlock icon on Safari title bar are not readable. The extension needs update to accommodate Dark Mode.
