It's a Firefox-specific issue. There so much uBO can do to deal with the way Firefox API fires the tabs.onUpdated event. Even trying to be a bit smarter to avoid the weirdness, I get:

Of course it makes no sense that https://github.com/issues became about:blank then back to https://github.com/issues, but that is what Firefox fires to the extension.

Can be closed - browser issue or something. I put this here only to be documented.

Well I think I will keep my fix to detect duplicate URLs in onUpdated (the code change seems trivial enough, but then it's difficult to foresee everything), but beyond that the logger will still look weird.

Happens on Chromium 63 too, I get 5 popup entries.
