How does OPNsense remember the GUI view settings?

[JasMan]

Hi all,
I'm wondering how OPNsense remembers the modified WebGUI views e.g. when I changed the column order or width in the firewall rules overview. Are they saved in the browser storage or on the firewall with the other user settings?

I'm asking because my modified views get very often lost. I can't determine a pattern.

Thanks
Jas

They're stored in your browser storage.

They're stored in your browser storage.

Thanks. Do you now how? As a cookie?
I'm not familiar with the possible methods to save such settings. But I would like to understand what's deleting them from my client.

It's not a cookie, it's localStorage.
