I can confirm that this add-on is no longer working with the latest Slack webpage. (mac0S 10.14x, iMac, firefox 68.0.1) - side bar disappears when moused over, page flashes periodically) -- Prior to this week, the theme worked just fine.

Is Dark theme for Slack Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Dark theme for Slack requires a few sensitive permissions. Exercise caution before installing.
