+Releases are done with GitHub actions:

 Alternatively, you can use [`@wxt-dev/auto-icons`](https://www.npmjs.com/package/@wxt-dev/auto-icons) to let WXT generate your icon at the required sizes.
 
+### Firefox `theme_icons`
+
+Firefox supports a [`theme_icons`](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/action#theme_icons) field on the toolbar action that swaps between a light and dark variant based on the current browser theme.
+
+When [targeting Firefox](/guide/essentials/target-different-browsers.md), WXT auto-discovers paired light/dark icons in the `public/` directory and attaches them to `action` (MV3) or `browser_action` (MV2). You only need to drop both variants next to your regular icons:
+
+```plaintext
+public/
+├─ icon-16.png         # regular (default_icon)
+├─ icon-light-16.png   # Firefox light theme
+├─ icon-dark-16.png    # Firefox dark theme
+├─ icon-32.png
+├─ icon-light-32.png
+└─ icon-dark-32.png
+```
+
+A size is only included in `theme_icons` if **both** a light and a dark file are present. The following filename patterns are discovered:
+
+<<< @/../packages/wxt/src/core/utils/theme-icons.ts#snippet
+
+Only `.png` files are discovered today, even though Firefox supports `.svg` - follow [#1120](https://github.com/wxt-dev/wxt/issues/1120) for updates.
+
+If you set `manifest.action.theme_icons` (or `manifest.browser_action.theme_icons`) explicitly in `wxt.config.ts`, WXT will not overwrite it.

+### Augmenting the Browser Type
+
+WXT's `browser` types are based on the `@types/chrome` package. That means some Firefox-specific APIs may not be typed, like `browser.sidebarAction`. If you want to add types for these APIs, you can augment the browser type to add them yourself:
+
+```ts
+// <srcDir>/browser-types.d.ts
+import '@wxt-dev/browser';
+import type { SidebarAction } from 'webextension-polyfill';
+
+declare module '@wxt-dev/browser' {

+  }
+}
+```

+>
+> ```sh
+> pnpm add @wxt-dev/browser

 ## Entrypoint Limitations
 
 Because WXT imports your entrypoint files into a NodeJS, non-extension environment, the `chrome`/`browser` variables provided to extensions by the browser **will not be available**.

+# Favicons
+
+[Chrome Docs](https://developer.chrome.com/docs/extensions/how-to/ui/favicons)
+
+Chromium-based browsers expose cached favicons through the `_favicon/` URL served from your extension. To use it, declare the `favicon` permission in your manifest and call `browser.runtime.getURL` with a `_favicon/` path:
+
+```ts
+// wxt.config.ts
+import { defineConfig } from 'wxt';
+
+export default defineConfig({
+  manifest: {
+    permissions: ['favicon'],

+function getFaviconUrl(pageUrl: string, size = 16) {
+  const url = new URL(browser.runtime.getURL('/_favicon/'));
+  url.searchParams.set('pageUrl', pageUrl);
+  url.searchParams.set('size', String(size));
+  return url.toString();
+}
+```
+
+::: warning Chromium only
+The favicon API is only available on Chromium-based browsers. Firefox has no equivalent, so `/_favicon/` URLs will not resolve at runtime there. If your extension supports both browsers, gate favicon usage behind `import.meta.env.CHROME` (or similar) and declare the permission per-browser.
+:::
+
+## Usage from a content script
+
+WXT does **not** add a `web_accessible_resources` entry for `_favicon/*` — not every extension needs one, and adding it unconditionally would expose internals to sites that don't need them. If you want to load a favicon inside a content script (for example, as an `<img src>`), add your own entry in `wxt.config.ts`:
+
+```ts
+// wxt.config.ts
+import { defineConfig } from 'wxt';
+
+export default defineConfig({
+  manifest: {
+    permissions: ['favicon'],
