Affects Navigator 2.6.6 on Ubuntu 24.04.3 LTS
When freshly installed, Navigator runs without errors. After installing additional programs, Anacoda applications e.g. Jupyter, can no longer be started. Instead, Thunderbird EMail starts every time. That’s funny, isn’t it? Upon closer examination of the problem, there appears to be a conflict with the GTK library.
anaconda-navigator Gtk-Message: Not loading module “atk-bridge”: The functionality is provided by GTK natively. Please try to not load it.

Some html files apear with the hint: This page should redirect you to a Jupyter application. If it doesn’t, click here to go to Jupyter. It works, but Anaconda cannot automatically open a Firefox tab.

But it seems Anaconda is Using GTK+ 2.x and GTK+ 3 in the same process.
