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. :-)

Was working fine but sometime in the last several months it stopped showing the status for SABnzbd. Not sure what's wrong as whenever I test the connection it says it's working. Tried the reset button and re-inputting the sabnzbd credentials but did nothing.

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!

Used to love it, but now it won't connect to Sabnzbd, no matter what I try.

Does not work - it says it can't connect to my SABNZBd

Basically useless when authentication is necessary. The gui is also not the best either. I might switch back to chrome for nzbget-chrome...
REPLY: I think the main missing gui feature (I know it involves more than just the gui) would be to be able to add nzb files straight to my nzbget with a button click. On the Chrome nzb plug-in this makes my life so much easier.

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!
