The issue you linked is specific to the `about:` pseudo-protocol. uBO's WebExtensions version works as intended on the web.

I know that, thanks. I posted it as a real life example of where webextensions are still not as powerful as the so called legacy extensions and wonder if that specific case still applies, is it fixed, planning to be fixed, or are there other specific examples where webextensions fall short.
Yeah, that specific case wasn't fixed; it appears that Mozilla doesn't intend to let addons run on `about:`. However, they did make `about:` respect DNT by disabling GA.

WebExtensions currently fall short when it comes to any addon that modifies the UI significantly (tree-style tabs etc), though it's been mentioned in some other comments here that they're talking to addon devs to extend the API where possible.

The irony is that since most people have DNT disabled having it enabled would make it easier for you to be tracked.

Why is that?
