Love this extension. It feels like the equivalent to RES for reddit (w/o the overkill). I never thought HN could be tweaked but this extension has changed my mind. It truly provides tweaks that HN needs.

I am having a similar issue, however, to one expressed on github (Jun 8, 2021) - titled:

[Firefox] Extension is broken (the loading wheel keeps spinning)

Most of this extension is working but the extension's Front Page sorting bar (sort by time/score, auto-refesh, hide read stories) - which is located above the stories/below the menu items was not working. This caused the spinning wheel.

This extension is so great, it allows easy blocking of certain features. So I disabled:

1. hide-read-stories
2. sort-stories
3. auto-refresh

BOOM! No more spinning wheel for features that weren't working anyway (for now). I'm still giving this extension 5 stars. It does so much! Even without the sorting, it's great. I do hope this issue gets resolved. I would really like to able to sort the front page stories by time (newest on top).

PS: Using Linux Mint: LibreWolf w/many extensions (main browser). Firefox with some extensions. Firefox *Profile* with zero extensions (ie, clean install of FF). They all had the same spinning wheel issue.
