+import MozillaConfigGenerator from '../../src/components/mozilla-config-generator'
+
+> mozilla 镜像目前正在测试中，行为可能不稳定，预计将在9月下旬完成测试。当下，不建议在生产环境下使用此镜像。
+
+此仓库为基于 Debian 的发行版提供了官方打包的 FireFox 浏览器，支持 amd64、arm64 架构。
+
+目前，Debian 稳定版只包含了长期支持版本 `firefox-esr`，而 Ubuntu 的 FireFox 切换到了 Snap 包。有需要的用户可使用本仓库提供的 APT 源。
+
+### 使用方法
+
+下面的内容修改自 [Install Firefox on Linux](https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions)。
+
+首先，导入和检查 keyring：
+
+```bash
+sudo install -d -m 0755 /etc/apt/keyrings
+wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null
+gpg -n -q --import --import-options import-show /etc/apt/keyrings/packages.mozilla.org.asc | awk '/pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0").\n"; else print "\nVerification failed: the fingerprint ("$0") does not match the expected one.\n"}'
+```
+
+#### APT 配置
+
+<MozillaConfigGenerator ubuntuVariant="ubuntu" />
+
+如有需要，在 `/etc/apt/preferences.d/mozilla` 配置 APT 优先级：
+
+```properties
+Package: *
+Pin: release a=mozilla
+Pin-Priority: 1000
+```
+
+最后，更新 APT 缓存并安装：
+
+```bash
+sudo apt update && sudo apt install firefox
+sudo apt install firefox-l10n-zh-cn  # 可选：中文语言包
+```
