I know you said you have reservations against installing add-ons, but that's really the best way to add features that aren't widely used. Modularity is flexibility. Set custom window title: https://addons.mozilla.org/en-US/firefox/addon/custom-titlebar-text/ https://addons.mozilla.org/en-US/firefox/addon/custom-titleb... All future tabs in a window keep the same container as the first: https://addons.mozilla.org/en-US/firefox/addon/sticky-window-containers/ https://addons.mozilla.org/en-US/firefox/addon/sticky-window... Both have links to their Github page if you want to look at the code and see what they do with their data permissions. I don't know what "fn+opt+leftarrow" is a shortcut to. I haven't used a home page in years, I save my tabs between sessions and use bookmarks and the built in search bar.
