mgbrowser v0.9.26 Experimental Preview

Desktop browser UX parity with Chromium: Omnibox search & live autocomplete
dropdown, chrome:// internal pages (newtab, history, bookmarks,
downloads, settings, version), Find in Page (Ctrl+F / F3 /
Shift+F3), persistent user-local Browsing History (Ctrl+H) & Clear Browsing
Data (Ctrl+Shift+Delete), pure-Rust File Downloads (Content-Disposition: attachment, <a download>, Save link as..., Ctrl+S Save Page, Ctrl+J),
toggleable Bookmarks Bar (Ctrl+Shift+B), Hard Reload (Ctrl+Shift+R), Stop
Loading (Escape / toolbar ×), Ctrl+U View Page Source, Ctrl+Shift+T
Reopen Closed Tab, Ctrl+N New Window, Ctrl+Shift+W Close Window,
Ctrl+1..9 tab switching, middle-click background link opening & tab closing,
tab-strip right-click context menu, mouse buttons 8/9 Back/Forward, and F11
EWMH fullscreen. Exact-source publication and public-install receipts are
recorded in the dated work log.

Linux x86_64 / X11 or XWayland, glibc 2.35 or newer. Rust 1.91.1, locked
dependencies and pure-Rust implementation backends (zero new crate dependencies).

Desktop Browser UX & Chrome Parity (v0.9.26)

• Omnibox Search, URL Normalization & Live Autocomplete (crates/mg-chassis/src/omnibox.rs):
  • Smart input classification distinguishes explicit http(s):// and
    chrome:// / about: schemes, localhost / IPv4 / dotted hostnames
    (defaulting bare domains to https:// and loopback to http://), and
    free-text search queries routed to the user's configured Search Engine
    (DuckDuckGo, Google, or Wikipedia, persisted in settings.json).
  • Live Omnibox autocomplete dropdown (Up / Down / Enter / pointer click,
    up to 6 suggestions) surfaces direct URL/Search actions, matching
    chrome:// internal pages, saved Bookmarks (★), and visited Browsing
    History (⏱).
• chrome:// Internal Pages:
  • Built-in styled HTML pages rendered natively through mg-sparkle with safe
    internal-only chrome:// link navigation: chrome://newtab (search hero,
    pinned bookmarks, recent history), chrome://history, chrome://bookmarks,
    chrome://downloads, chrome://settings, and chrome://version (plus
    about:blank).
• Find in Page (crates/mg-chassis/src/find.rs):
  • Ctrl+F opens the floating Find bar with live case-insensitive substring
    matching across positioned Frame::text_runs, live N/M match counter,
    translucent yellow (#ffe066) inactive and orange (#ff922b) active match
    highlights, automatic viewport scroll-into-view, F3 / Enter / ▼ next
    match, Shift+F3 / Shift+Enter / ▲ previous match, full clipboard
    support (Focus::FindInput), and Escape / × dismissal.
• Persistent Browsing History & Clear Browsing Data (crates/mg-chassis/src/history.rs, src/history.rs):
  • User-local $XDG_CONFIG_HOME/mgbrowser/history.json (O_NOFOLLOW, 0o600,
    advisory flock .history.lock, 2 MiB read cap, 512 deduplicated
    entries sorted newest-first with visit counts and timestamps).
  • Ctrl+H and Menu > History open the paginated History modal with click
    navigation and per-item Remove; Ctrl+Shift+Delete clears browsing
    history, session cookies, HTTP/render caches, and the download list.
• Pure-Rust File Downloads & Save Page (crates/mg-chassis/src/downloads.rs, src/downloads.rs):
  • RFC 6266 / RFC 8187 Content-Disposition: attachment and binary MIME
    detection (application/pdf, application/zip, application/gzip, etc.),
    <a download="..."> link activation, context-menu Save link as..., and
    Ctrl+S / context-menu Save page as... stream downloads without navigated
    page loss.
  • Safe host persistence into MGBROWSER_DOWNLOAD_DIR / XDG_DOWNLOAD_DIR /
    ~/Downloads using sanitized filenames, O_NOFOLLOW, create_new(true),
    0o600 mode, and automatic (1), (2) collision numbering (8 MiB per
    download cap), inspected via Ctrl+J / Menu > Downloads /
    chrome://downloads.
• Bookmarks Bar, Toolbar Reload/Stop & Page Source:
  • Toggleable Bookmarks Bar (Ctrl+Shift+B or Menu > Settings > Bar) renders
    one-click saved bookmark pills directly beneath the main toolbar.
  • Active page loads turn the toolbar reload button into Stop (×, or Escape
    to cancel in-flight navigation); Ctrl+Shift+R / Shift+F5 performs a
    cache-bypassing Hard Reload (Cache-Control: no-cache, Pragma: no-cache).
  • Ctrl+U and context-menu View page source open the raw HTML document in
    DevTools Sources.
• Tabs, Windows, Pointer & Fullscreen Shortcuts (src/desktop.rs, src/workspace.rs):
  • Ctrl+Shift+T reopens closed tabs from a 32-entry LIFO stack; Ctrl+N
    opens a new native browser window; Ctrl+Shift+W closes the current window;
    Ctrl+1..8 selects tabs 1–8 and Ctrl+9 jumps to the last tab.
  • Middle-clicking (Button 2) a page link opens it in a background tab
    without stealing focus; middle-clicking a tab in the tab strip closes it;
    right-clicking a tab opens a native Tab Context Menu (New tab,
    Duplicate tab, Reload, Close tab, Close other tabs,
    Reopen closed tab); X11 mouse buttons 8 and 9 navigate Back and
    Forward; F11 toggles EWMH _NET_WM_STATE_FULLSCREEN.
