After installing Firefox 123.0 I ran a Mullvad Connection check https://mullvad.net/en/check and found I had a DNS leak. Turns out that Firefox had changed the settings under "DNS over HTTPS" so that my Mullvad DNS wasn't being used any more. After changing this setting to "off" in Firefox, the Mullvad check passed.

I should have mentioned, I am running the Flatpak version of Firefox on Kubuntu 23.10
