Previously we hid it on purpose because it caused pretty major layout
issues when urlbar's grid layout interacted with xul layout.
But now with flexbox it should work just fine.
This adds a 2px margin to periphery which acts as buffer-zone so when
a tab is added or removed the layout won't immediately cause
overflow-mode to activate
This makes sure that the icon stays visible unless your theme colors
explicitly tells otherwise. Setting full fill-opacity makes the icons
look same between pinned and non-pinned tabs.
Previously this just used --toolbar-bgcolor which may have transparency
leading to poor readability. Similar results might still happen if theme
has poor text-background contrast, but now the result should be less
unpredicatable.
This patch makes the placeholder borders use transparent borders instead
of color derived from your theme. Instead the background-clip is
extended to border-box (which it already was on non-Windows systems)
-webkit-box doesn't work correctly in Firefox 112 and 113 so lets
default to flex again and make webkit-box opt-in. It is required for
Fx 114 though, but nightly users need to opt-in to using it.
This patch simplies a lot of selectors and makes the changes apply to
buttons in menubar and tabs toolbar. With the exception of
tabs-newtab-button. Additionally, this makes the style
much better support dropdown buttons, combined buttons and findbar
buttons.
Flexbox model will replace old xul box as the default display model so
this patch adds support for that in a whole bunch of styles.
A lot of style rules are marked as "Fx < 112 compatibility" rules and
those can be removed when 112 hits release.
This patch patch makes the link generator handle "+" characters in the
filename.
Additionally, file-target list should now have more-correct grid-layout
without producing overflowing rows.
The category list is fixed-positioned sidebar which hopefully makes
mobile rendering work better than before.
