Firefox opens second window when triggered by external link
I have an issue with my Firefoxes, but I am not sure if it is a bug or a feature.
Whenever I click on a link inside an app, e-mail or whatever, Firefox opens up with the usual startpage in the background and the linked page in the front. Is that normal behaviour? I would rather have Firefox open 1 window with the link I clicked on and without an additional window for the generic Firefox startpage.
I am also using the Multi-Account container addon, but experiencing the same behavious without that addon.
Thanks for your insights :). Henning
