I’ve enabled “Delete cookies and site data when Firefox is closed” but while all cookies gets deleted, some random site data does not. Are my settings wrong, is this a bug, and what even is that data?

Additional Info: I use RFP, want to keep browsing history and site settings. Thank you very much.

    8 bytes is enough to store 18,446,744,073,709,551,616 (18 quintillion) different values, more than enough space for a fingerprint ID. The size of the data shouldn’t factor into the potential threat.

      Oh for sure, I just wonder if the size being the same on 2 of them is a result of Firefox storing some default data there on cleanup by accident.

        Oh, I get it now! In my sleep deprived state I missed that two of them had the same size. That seems like a reasonable guess, I’m just paranoid about cookies :P

      Except the actual content is very likely boilerplate stuff.

        My point still stands. The size of data says nothing about its contents. If OP is concerned about this from a security or privacy perspective, you shouldn’t be writing them off because it’s only 100 bytes.
