When I click on a campaign, I land in the "Details" tab of the campaign.
Then I click on the "Design" tab of the campaign.
In Safari or Chrome, the Design tab already shows a preview of the email.
In Firefox (V125.0.1 on macOS 13.6.6 (22G630)) the email flashes and can be seen for a moment, then it disappears. In the Preview tab, everything is OK in all browsers.
