Pasting here from Slack:

151.0a1
log in with account with 90% usage - VPN OFF - 50GB of 50GB usage
turn ON VPN => 3GB infobar + warning displayed in current window, infobar is not displayed in new window (just the warning)
turning it OFF => triggers the infobar in a new window as well
same applies if I start from VPN OFF in main window
On Raluca's PC this only applies while starting with VPN OFF in main window;

150.0b2
log in with account with 90% usage - VPN OFF - 3GB of 50GB usage infobar and warning displayed in current window;
turning it ON => triggers the infobar in a new window as well
same applies if I start from VPN ON in main window
On Raluca's PC this only applies while starting with VPN OFF in main window;

149.0
log in with account with 90% usage - VPN OFF - 3GB of 50GB usage infobar and warning displayed in current window; both infobar and warning NOT displayed in new window
turning it ON => triggers the infobar/warning in a new window as well
same applies if I start from VPN ON in main window
On Raluca's PC this only applies while starting with VPN OFF in main window;

The issue also applies if the infobar is dismissed from the "X" button -> at turn ON it is shown again - let me know if this needs separate tracking.

Comment 4

[Becca]

Yes, if you could file a separate bug for 'infobar does not stay dismissed after clicking 'X' button' that would be helpful!

Tracked the infobar not being dismissed issue here - https://bugzilla.mozilla.org/show_bug.cgi?id=2028819.

[Michael Hynson]

After discussing this with fchasen and rking, we'll update the expected behavior as follows:

• If an infobar is displayed, it will be dismissed when the VPN panel is open and contains a message bar.
• If the VPN panel is open with a message bar, an infobar will not be displayed.

Verified this as fixed using Firefox Nightly 152.0a1 (21-04-2026) and Firefox Beta 151.0b1 on Windows 11/macOS 26.
Changing the VPN state does not impact the infobar/warning behavior.
