Original GitHub issue: https://github.com/netbirdio/netbird/issues/5710

Describe the problem

netBird fails to launch Edge/Chrome, FireFox prompts an error about not "Profile Missing" windows, with text "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

Closing out of FireFox, or Edge/Chrome fully (including any PWAs that use the default browser),
Then netBird can usually open and process sign in.

Can reproduce on both Edge, Chrome and FireFox.

Management v0.67.0
Dashboard v2.35.0

To Reproduce

Steps to reproduce the behavior:

Have NetBird require re-auth when disconnected
Have browser already opened
Connect NetBird
Browser either fails to open new tab/window or in FireFox, we get profile error.
Close all browsers
Able to then connect (you can open browser first, or let netBird open it, but this seems to be tied to the 2nd time netBird needs to auth.

Expected behavior

netBird should open a new tab if default browser running, netBird should start a new instance if default browser not opening or running.

Are you using NetBird Cloud?

No, Self Hosted.

NetBird version

Management v0.67.0
Dashboard v2.35.0

@JerBar commented on GitHub (Mar 26, 2026):

This seems to be GUI only.

when we do a netbird up from CLI, it seems to always open the browser. FYI.

@LufinityLucas commented on GitHub (May 3, 2026):

Nor sure if it's related, but we're seeing issues that the Netbird client on Windows is opening a new Edge window with a new profile when re-authentication is triggered (instead of a new tab in the current Edge window, with the user's current profile). We're using the cloud management platform and are Entra ID integrated.

Having the same problem with v0.74.6. CLI works fine, seems to be an issue with netbird-gui specifically. Restarting the GUI fixes it.
