Browsers have cookie and anti-tracking enforcement issues
A team of Belgian researchers from KU Leuven analyzed third-party cookie policies of seven major web browsers, 31 ad-blockers and 14 anti-tracking extensions and discovered major and minor issues in all of them.

Major issues include Microsoft Edge's unwillingness to honor its own "block only third-party cookies" setting, bypasses for Firefox's Tracking Protection feature, and use of the integrated PDF viewer in Chrome and other Chromium-based browsers for invisible tracking.
Fun fact, I tested all the exploits on Vivaldi 1.15 and Chrome 68 and no cookies where saved (due to Adguard Desktop APP).
