I updated the neutered script from googletagservices.com, I found the site was throwing an error because of a missing method in uBO's neutered version of the script. Not sure whether it's a new method or whether I missed it when I created the neutered script.

There is no filter in EasyList or EasyPrivacy for googletagservices.com (hence it worked fine with ABP), it's something I added to "uBlock filters - Privacy" a long while ago, and created a neutered script to replace the real one to minimize web page breakage.

If you want uBO to behave just like ABP blocking-wise, just select the same exact filter lists -- though I strongly advise you at least keep "uBlock filters" for best results.

For reference, ABP comes with only EasyList enabled by default + a regional list if applicable. Privacy-wise though, you lose a lot by not using EasyPrivacy, Peter Lowe's and other uBO's own filter lists. See this graph[1]: second bar is when only using EasyList + "uBlock filters". Third bar is uBO's default list/settings.

Are you sure it's not one of your other extensions? It works fine with Firefox Nightly and uBlock Origin on Windows 10.

I went to check, you're right, on my Chrome 55, Windows 10 and uBlock 1.10.0.

Yep, that's broken on Firefox 50.0.2 on Linux Mint 17.3

Worked for me.

Chrome 55 and UBlock 1.10

Works for me as well. Firefox 50.0.2, uBlock 1.10.0, Windows 10

uBlock Origin uses less resources than AdBlock Plus, so it's not an issue for me.
