It's very useful but it often occurs that, after few minutes of normal working, suddlendly happens that it's impossibile continue browsing (all web sites unreachable, no connection, not possible restart any vpn tunneling). There's no way to restore the functionality. You can only restart the browser completely and the extension will restarts to work. This is the only way. Quite frustrating.

A little slow navigation

While it's possible to use it in tandem with the Desktop app via split tunneling, the overall experience is frustrating.
Unlike the full version, the Firefox version suffers from intentionally slow speeds (with "a cap of 100 Mbps set on squid services to prevent the saturation of server ports through proxy connections").
NordVPN itself lives up to the hype, but it's better to just use the Desktop version at the moment.

I wasn't going to download the extension at first, but I'm glad I did. For whatever reason, split tunneling doesn't seem to work right with the NordVPN windows 11 app, so using the extension works out really well.

Leaks DNS without DoH enabled.
But with DoH enabled, DNS resolving is slower, and after a while it will fail to resolve DNS requiring a browser restart frequently. Its just broken at this moment.

Browser Extension needs a stable update since January 15, 2025. Extension is broken, login not working, connection not going thru.
