User Reviews

Reviews largely praise NZBDonkey for reliable SABnzbd/NZBGet integration, easy setup, and time-saving NZB management, including LAN use. The developer’s responsiveness is also highlighted. Common concerns center on stability and UI issues: pop-up searches that vanish, a blank window after Firefox updates, and the settings page auto-opening on restart. Additional drawbacks include occasional NZB renaming errors and questions about license/source code transparency. Overall, it’s well-liked for core functionality with some reliability and transparency caveats.
Pros
  • Reliable integration with SABnzbd (and NZBGet) for sending NZBs.
  • Easy to install and configure with simple setup and one-click use.
  • Useful for managing NZBs and saving time across Usenet, including LAN usage.
  • Developer is responsive and provides support when issues arise.
Cons
  • UI stability issues: search pop-ups can disappear, the extension may show a blank window after Firefox updates, and the settings page can auto-open on each restart.
  • Occasional NZB renaming errors that can mislabel files.
  • Questions about license/source code transparency and privacy concerns.

Great program! I am looking to replace nzbunity. The only difficulty I am having is that the program works great as long as you have the pop up dialog for the nzb sites set to on. But, if you set NZB file download interception > Edit Domain > NZBSettings Dialog to off, the program no longer forwards the requests to nzbget. The program works fine with this on, but not with the dialog turned off. I would like to have the dialog turned off, so I can simply click nzb's with one click, like I used to in nzb unity ( nzb unity was too slow, hence the reason for my interest in using your application instead). This would completely "enhance my user experience". ( I know, I used the language 'marketing babble'. ) [Edit: I don't know exactly what is going on, but now this function works fine with the dialog turned off. ? I am leaving this up, however, as there may be something else going on, and bug reports can be useful. I didn't do anything different, other than turning these dialogs off in the nzbdonkey settings, and I closed the settings page in firefox for nzbdonkey. Perhaps closing the page made a difference? I don't know...] [ Second Edit: Your extension is MUCH FASTER than nzbunity, and this was what I was after. The only potential change I could see being useful would be to put in a setting so the extension only informs you of a failure, but this is really not much of an issue. The red colour you use on the failure is attention grabbing enough, and I can ignore the other status messages quite easily, and, fortunately, the program doesn't sit there making me wait before I click on the next title. I can click on as many titles as fast as I want, and the extension handles all of this flawlessly. nzbunity used to slow down the loading of my web pages, and I would have to wait for the extension to finish processing the web page so I could click on links, and your extension doesn't have any of this kind of impact on performance or loading of web pages, so really, nzbdonkey does exactly what I need it to do, with alacrity, and without slowing down the browsing of nzb sites. nzbdonkey is really the Cat's Meow, and gets my stamp of approval of being truly "Awesome Sauce"! ] In any case, keep up the fine work. You are doing a great job. Thanks ever so much!!!

I am testing this out on Zen browser. It works well sending nzb'd to both SABnzbd 7 NZBGet from my indexers, but when I click on the extension to search via Easynews the pop up shows for a fraction of a second then disappears! Would love to get this to work.

Funktioniert wie erwartet! Und zwar ganz ohne NZBDonkey als separate Anwendung die man noch per ini-datei konfigurieren musste. Addon installieren, SABnzbd-Server und deren API-Token hinterlegen, Suchmaschine auswählen und das alles per Klick. Wunderbar, Dankeschön Tensai!! Nur, warum nur gibt es dieses Addon nicht für den Firefox unter Android und warum brauche ich unter Android eine separate App?

Is NZBDonkey 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.

NZBDonkey requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

NZBDonkey is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
