I interact with this extension every day, essentially. Has always been flawless in terms of working with my indexer of choice.

Until you upgrade to hosted seedbox this is the most excellent pairing of NZB indexer with usenet fetching via nzb. It is easy to setup (with sabnzbd+)

It has all the features I need.
Particularly like the possibility to add a Newznab site manually (mine is nzbplanet)
Big thanks to the developpers.

Excellent extension, works great, nice UI. A solid improvement over SABconnect++.

I'm very impressed. I never heard of this software before. It was recommended by one of my indexers. I'm still playing around with it between my laptop and PC, but I have concerns it's not saving my SAB information. I'll keep using it to see if what I think is a problem reproduce. Other than that, it's a REALLY handy tool. Nice not having to tediously enter my SAB information for ever index. :-)

Works for me in latest version of Firefox

The SSL cert for sabnzbd is invalid by default as it's self-signed. You need to open the site in Firefox first and a security warning will be shown. Add an exception for the site and then add your connection details to NZB Unity and it should work fine.

Finally a replacement for nzbfox. Thank you so much!

Functionally this add-on is just about there and works well. It mostly needs UX and design improvements.

It's currently the only add-on in this category that works with Firefox 57, so I can't complain too much!

Great functions and easy to use!
