Hi,
I don't use HN without this extention anymore. Any webextention that would work?
legacy add-on for FF: https://addons.mozilla.org/en-us/firefox/addon/hacker-news-mark-all-read/
chrome version: https://chrome.google.com/webstore/detail/hacker-news-mark-all-read/fghfahcbhpdeeaaofcefaoodmfejieok?hl=en
Maybe chrome store foxified will return to safe the day...
