The ubo extension does work in orion, but I remember having to go somewhere deep into settings to make it actually be enabled. I don't remember exactly how I did it but eventually after a few restarts of the browser I got it working.
I did compare against other adblock systems on ios and found it to be the best option, as other adblocks either gave broken webpages or just didn't work at all.
