If you have anti-trackers or ad-blockers installed in browsers, it may be possible that some functions of Hashnode might not work properly.
When I enable privacy badger, certain parts of the website like images and fonts does not load, to counter this I have to unblock cdn.hashnode manually.
Also, if I block all the third party cookies in firefox, Hashnode just logs me out. When I try to login, it redirects me back to homepage.
Untill Hashnode fixes this, you have to allow third party cookies and unblock all the hashnode domains from privacy badger.
