подведение итогов из этого комментария:
So things to keep in mind if you are eager to believe the above explanation from Stylish representative:
— the attempt at obfuscation (no valid reasons whatsoever).
— the unique id «appUniqueId» (no valid reasons whatsoever).
— the full URL visited (could be just the hostname and only on 1st visit + possibly a user-initiated update manifest in case new user styles become available for a specific site already visited.)
— the full referrer URL (no valid reasons whatsoever).
All these are not necessary for the official stated goal — and of course the worst is that the claim that the data is anonymous is false. If the will to not collect browsing history was really genuine, the extension would have been written in a very different way to accomplish the stated goal.
My advice is if you *really* need that extension, disable the option to send supposedly anonymous data — so far, as of writing, it seems it does what it says. Unfortunately as is too often the case, the default is not pro-user i.e. not opt-in so a lot of people will end up having their browsing history collated (even if using a VPN).
