* the history and saved bookmarks can at least be accessed conveniently
* through the navigation search.
* - fullscreen is hidden: not available in FF for android either, the

* that don't expect apps to go fullscreen (i.e. in Phosh, as soon as
* the on screen keyboard is triggered, the top and bottom bars of Phosh

Updated CSS files:
single_tab_mode.css
single_tab_mode_with_space_for_1_item.css
single_tab_mode_with_space_for_2_items.css
numbered_tabs.css
The recent FIrefox-ESR update has added close buttons next to the tabs in the Tab Manager Menu, allowing me to create the True_Mobile_Mode style (true_mobile_mode.css
).
