Slack stopped working

[nofishonfriday]

What happened?

I used to be able to click on 'You can also use Slack in your browser' to use Slack in Waterfox, but since recently when clicking on it, it just loops back to this page. Happy to provide more details (if I can) when useful.

G6.0.20

Reproducible?
