Does uMatrix still exist (maintained)? I remember reading it is being discontinued.
(I occasionally used it for curiosity, but found it too tedious in the long term. I have settled on CookieAutoDelete, which seem to address most tracking. Not many seem to run a completely server based fingerprint database.)
It is not maintained but the latest version[1] still works fine, and I will continue to run it until that is no longer the case.
[1] A beta that you can download from the github page. I assume the latest stable version also works fine, but the beta had a few additional bugfixes and features and I haven't encountered any instability.
