So it's not a privacy issue, it's an ad issue. Which doesn't show, it's blocked.

I don't understand what did you intend to respond to with this. as filtering instructions get more out of date, the addon's privacy protections will also fail.

What does uBO do different here?

on youtube? if you fire up firefox, install uBO, ocannote uBO logger and open a youtube video page, you'll see what it does. I don't know what it does different because I don't happen to have an itemized list of what does uBO lite do, but I suppose it has a logger function too, and you can compare it.

uBO mostly protects against tracking here. automatically selects no in the google data sharing dialogue, employs lots of scriptlets (documented on the wiki) to set variables used by youtube, to unfuck youtube in other technical ways, and to block behaviors it shouldn't even think about doing (why does it need a scriptlet that blocks writing the clipboard??), blocks ad video segments, hides annoying things from the UI because I have lists enabled that do that.

but there is something I can confidently say it does differently: it always works from up to date, detailed filterlists. lite cannot do that.

Just FYI - that only happens to me on YouTube every once in a while. Like, three times this year for a day or two.

so far releases go public within a day, but don't think that will go so smoothly when google gets the urge again to fuck up ad blockers, and addon uodate review suddenly takes days to weeks, or they find some idiotic non-existent problem as the play store team loves to do with open source apps.
