HTTP cookie headers about umatrix

[gorhill]

Looks fine from here, it tells me I've blocked over a 1,100, and that is after I restarted the extension two hours ago.

Things that can cause uMatrix to not see many cookie headers to foil:

• You have "Block third-party cookies and site data" selected
  • It is not selected on my side because I want to test
  • It is better if selected, even with uMatrix, because this also takes care of all sort of site data, not just cookies.
• Cookies are allowed for 1st-party

If you have the two conditions above reunited, there won't be any cookie header to foil.

Hello gorhill,

Thanks for the response. I understand now. I have the two conditions as you posted above (also when using HTTPSB) but was just confused as to why HTTPSB reported them blocked and µMatrix does not. I suppose this is due to a difference in code between the two. Thanks again.

The code for that part was not really touched. Are you blocking 1st-party cookies in HTTPSB?

Hello gorhill,

Now I fully understand. With HTTPSB, I had it set to "block-all/allow-exceptionally", which of course blocked 1st party cookies. I am using µMatrix in default mode which is allowing 1st party cookies. With both, I have selected "Block third-party cookies and site data" in Chrome's settings. Since I am now allowing 1st party cookies in µMatrix, I will not see any "HTTP cookie headers" being blocked. All due to the differences in how I have HTTPSB and µMatrix set up. Thanks for explaining this and helping me understand!
