Does anyone have an idea of how to do it or even if it’s possible? Because as I am paranoid I would like to close my Mozilla account.
BONUS: How to prevent the installation of new extensions from opening welcome pages because it’s very annoying thank you.
All except the Logins and Credit cards option is selected. It did not work when I moved from Firefox to Icecat, or IceCat to LibreWolf. I had to install the addons manually.
Were Flatpaks, Snaps or AppImages involved ?
