Enable -Wexit-time-destructors for all in-tree library targets and
update process-lifetime library statics so they no longer register
exit-time destructors. Long-lived caches, lookup tables, singleton
registries, and generated constants now use NeverDestroyed or leaked
references where the data is intended to live until process exit.
Update LibWeb, LibLine, and the binding generators so regenerated
sources follow the same rule instead of reintroducing destructed
statics.
This as a pesudo third mode to vertical tabs. Now when the vertical tabs
are collapsed, users can enable a setting that will expand the vertical
tab area on hover. Unlike full expansion, the hovered vertical tab area
will cover the web content area to avoid pushing the web content area
around.
Add an advanced setting for rounded browser window corners. On macOS,
Qt browser windows now use a layer-backed corner radius, and clear it
when maximized, fullscreen, or the setting is disabled.
Hide the setting from about:settings on other platforms for now since Qt
does not expose a native antialiased window corner API there.
This adds a setting to enable vertical tabs and to expand/collapse them
if enabled. This setting is hidden for UIs that do not support them
(which is every UI as of this commit).
As we approach an alpha release, it will generally make less sense to
show all of the debug options in the application menu. Add a persistent
setting to show this menu, disabled by default.
Add a content_blocking.list_paths advanced setting backed by a JSON
array. This lets content blocker list paths avoid splitting one string.
The about:settings editor presents array values as one path per line.
It persists them as arrays.
Load configured paths before command-line paths so temporary lists can
still be appended for a single browser session.
Register debug.process.show_web_content_process_id and use it to append
the active WebContent process ID to tab titles and tab tooltips in the
Qt, Gtk, and AppKit frontends.
Keep the stored page title unchanged so toggling the preference can
refresh each tab without waiting for a new title update.
Add a small registry for config variables backed by JsonValue defaults.
Persist values under configVariables and expose the registry through the
Advanced tab in about:settings so every key remains visible and
filterable.
Use the default JsonValue type for validation instead of maintaining a
parallel type enum.
Remember the zoom level for each host so that returning to a site
restores the zoom the user previously chose, matching what other
browsers have done for years.
When the user zooms in, zooms out, or resets the zoom, the resulting
level is written to Settings keyed by the current page's host. On
navigation, when a view's URL host changes, the stored level for the
new host is applied (or the global default if there is no override).
Per-host zoom changes are broadcast through the SettingsObserver so
that two tabs viewing the same host stay in sync as soon as the user
adjusts zoom in either one. Zoom changes from within the page (such
as internals.setBrowserZoom hook) and the WebContent restart path do
not persist, only user-initiated zoom changes do.
The tabless page with an ever-growing list of vertical cards was getting
a bit disorganized. This moves each section of the settings page to be
its own tab, with buttons to switch tabs. Some of this presented the
opportunity to migrate settings from popup dialogs to be directly in the
tab, such as the disk cache settings.
The global "restore defaults" button has also been removed. The more
settings we have, the less sense such a button makes sense. Individual
settings can have a reset option where it makes sense.
This adds a settings box to about:settings to allow users to limit the
disk cache size. This will override the default 5 GiB limit. We do not
automatically delete cache data if the new limit is suddenly less than
the used disk space; this will happen on the next request. This allows
multiple changes to the settings in a row without thrashing the cache.
In the future, we can add more toggles, such as disabling the disk
cache altogether.
Global Privacy Control aims to be a replacement for Do Not Track. DNT
ended up not being a great solution, as it wasn't enforced by law. This
actually resulted in the DNT header serving as an extra fingerprinting
data point.
GPC is becoming enforced by law in USA states such as California and
Colorado. CA is further working on a bill which requires that browsers
implement such an opt-out preference signal (OOPS):
https://cppa.ca.gov/announcements/2025/20250911.html
This patch replaces DNT with GPC and hooks up the associated settings.
We had a bit of an awkward setup where we want the Application to be a
SettingsObserver, but neither the Settings object nor the Application
itself was fully initialized by the time the observer was created. So
we invented a deferred observer initializer specifically for the
Application.
Instead, let's just create a dedicated observer subclass that is owned
by the Application. We can then create it once we have the singleton
Application appropriately set up.
This allows the user to store custom search engines via about:settings.
Custom engines will be displayed below the builtin engines in the drop-
down to select the default engine.
A couple of edge cases here:
1. We currently reject a custom engine if one with the same name already
exists. In the future, we should allow editing custom engines.
2. If a custom engine which was the default engine is removed, we will
disable search rather than falling back to any other engine.
This implements a setting to change the languages provided to websites
from `navigator.language(s)` and the `Accept-Language` header. Whereas
the existing Qt settings dialog allows users to type their language of
choice, this setting allows users to select from a predefined list of
languages. They may choose any number of languages and their preferred
order.
This patch only implements the persisted settings and their UI. It does
not integrate the choses languages into the WebContent process.
This implements an autocomplete engine inside LibWebView, to replace the
engine currently used by Qt. Whereas Qt uses the Qt Network framework to
perform autocomplete requests, LibWebView uses RequestServer. This moves
downloading this untrusted data out of the browser process.
This patch only implements the persisted settings and their UI. It does
not integrate this engine into the browser UI.
The idea with the UI here is that it will serve as a generic component
for all site settings, such as autoplay, notifications, etc. When the
site settings dialog is opened, it is filled with the requested setting
data, and messages sent to the browser process are based on the setting.
This patch only implements the UI and persisted settings. It does not
apply autoplay changes to the WebContent process.
This adds a WebView::Settings class to own persistent browser settings.
In this first pass, it now owns the new tab page URL and search engine
settings.
For simplicitly, we currently use a JSON format for these settings. They
are stored alongside the cookie database. As of this commit, the saved
JSON will have the form:
{
"newTabPageURL": "about:blank",
"searchEngine": {
"name": "Google"
}
}
(The search engine is an object to allow room for a future patch to
implement custom search engine URLs.)
For Qt, this replaces the management of these particular settings in the
Qt settings UI. We will have an internal browser page to control these
settings instead. In the future, we will want to port all settings to
this new class. We will also want to allow UI-specific settings (such as
whether the hamburger menu is displayed in Qt).
