I don’t care for themes, just need night mode. I need the option to throw out any taskbars except fot tabs and address bar. Including any search window. I need a zoom slider at the bottom right corner, and this is a must. It’s also nice to have these things built in instead of looking for extensions. And You are right, o haven’t looked into Firefox for a long time.
The “cradle” for going forward and backwards plus swipes for closing a tab, refreshing and opening a new tab.
