FeatherBrowser

Minimal Windows desktop browser built in C# on Edge WebView2. Small footprint, automatic background tab sleep, built-in request blocking, and Chrome extension support.

Included

• Uses the system Edge WebView2 runtime instead of shipping a duplicate Chromium bundle.
• Sleeps idle background tabs via TrySuspendAsync() and monitors live process-tree RAM.
• Supports unpacked and .zip Chrome extensions (MV2/MV3) plus lightweight CSS/JS userscripts.
• Network-level ad and tracker blocking, bookmarks, history search, downloads, private windows, and DevTools (F12).
