Seems very fast and efficient, and I'd say less clunky than using the Nord application. Which is fine if you mostly use Firefox as your browser of choice.

Used to work fine. Completely broken now.
Can't even sign in anymore.

edit: they fixed their sh*t and it's working again just fine.

It can't be a coincidence that many people besides me have been experiencing massive losses in speed for a few days now. Fix your add-on. After all, we pay money for it

Update: Contacting the support is frustrating.
Summed up: clearing cache, reinstalling NordVPN add-on and deactivate other add-ons. Despite my messages about many others having the same problem, the supporter didn't think about the NordVPN update as the cause of the problem.
I hope, there is a bug fix coming soon. Otherwise I'll look for a reliable vpn provider.

A friend told me that I could simply add NordVPN as an extension on my Firefox rather than download the entire program onto my desktop computer system and it does the same thing. Ever since the last update, this extension slows Firefox right down to a crawl where the new tabs I do searches in or just click on a certain website in one of my bookmarks will not even show results whatsoever. I decided to turn off the extension, download the entire program and install it onto my computer system that shows in the system tray as it did before and Firefox works quickly like it did before I added the extension. Like so many have already said, this extension needs improvement to an update that will make it work as it should.

unfortunately this add-on doesn't work in Saudi Arabia for months now , tested it on multiple connections / pcs , the only time this add on work if someone use VPN and hotspot then it will work , my guess is ISP blocking the connection

卧槽这尼玛带劲

Extension works. No connection issues. It is fast, even though I have somewhat average computer.
