Great add on should have the same functionality as in the Windows App.

Solid extension but does occasionally disconnect and experience minor issues never encountered on the standalone app

Cool for if you want your browser traffic, but not other apps, going thru vpn. Has some setting that's not obvious which prevents reset button working though. Probs just me, but these things should be idiot proof, IMO. Works a treat apart from that.

Once you have jumped all the hoops NordVPN is good, but you could design your website to make things easier to find without having to visit half a dozen different Nord pages.

It gets better. the most demanded feature -- whitelisting (i.e. when vpn is active and used only with listed sites, which is the most sensible mode in a case when your government breaks the Internet part by part) is absent, though blacklisting was added lately. There was some problems with UI (I needed to relogin sometimes), but overall not bad, get things done.

This add-on was causing me issues very often, like for others. Then I tried disabling all other add-ons and it worked! It's working even all disabled add-ons are re-enabled again so I can't tell what caused this. It may just be some other extension, it may be Firefox glitch or NordVpn extension issue. Until I figure this out it's 4 stars. Otherwise it's 5.

UPDATE January-2022:
No issues since using v2.40.0; it seems faster and I also like the new 'Pause' feature. Giving it 3 more stars.

June-2021:
It got really bad, broken Login! Claims "succesfully connected" to NordVPN in pop up window while exension icon shows it is not. NordVPN suggests to reinstall the extension but that's just a temporary fix; I'm getting tired of re-installing every week or so and perhaps it's time to trash it if NordVPN can't resolve it for good.
