Previously if Firefox was in fullscreen mode and toolbars would autohide
(per Firefox normal setting) then this style would cause content area to
be pushed way too far up because of computed margin-top on
navigator-toolbox. This patch makes navigator toolbox use margin
computed from tabs toolbar height.
These rules were once needed to make sure that invisible toolbox didn't
steal pointer events from sidebar. Not needed anymore, and this removal
also fixes#305
For some reason individual .bookmark items in the toolbar are being
rendered in Firefox 96, even though the toolbar itself is hidden. This
patch applies a simple visibility:hidden to all of them.
Bookmark items in the toolbar may not be same height on all systems,
generally the text size on Linux is bigger than on Windows for example.
This patch changes the height to use min-height on bookmark items and
removes their individual block padding. Thus, thee effectively have
variable block-padding depending on the text size.
In addition this patch removes few pre-proton workarounds because those
don't need to be supported any more.
