I use old.reddit.com, and had trouble logging in from there today. “Too many redirects”. I also use the Redirect to old.reddit.com extension. When I disabled that, the login link it now takes you to is https://www.reddit.com/login/. That, of course, takes you to www.reddit.com.
The old ‘popup’ login box has been removed. I also noticed that the in sub logins where they used to have username/password entry boxes have been removed.
More reddit enshitification to try and make us use their horrible UI.
They’ve now fixed/reverted it to the old operation.
No doubt because of my scathing post here.
