I've got the same setup as you. Are they wrong or just not showing? Console errors?

No console errors, just not showing. Let me know if there is anything I can send to help debug.

Also, not sure if this is by design, but after I post an in-place reply, I have to reload the page to see my post. However, upon editing a post, the page reloads immediately. I didn't see any error in the console.

I was conflicted about whether or not to update new comments inline or force a page refresh. So the behavior with the comments is intentional. I may end up changing it if it's confusing.

As for the other problem, I'm confused about why that's the only thing not working. Are you running any other extensions that could be conflicting?

Makes enough sense re: problem #1. Re: the unread counts not showing up, this still occurs for me even when Hacked Hacker News is the only enabled extension.

EDIT: I have no idea why, but as I was hammer-clicking on the Hacker News main button, all of a sudden the unread counts started to appear. I wonder if there was some cache issue or something such as that.
