自己顶。谁告诉我怎么办？手机不能扫描。我甚至退出了手机登录，电脑版的仍然让我搞个手机去扫描二维码。

当然最缺德的就是明明MAC版本的火狐一直用着，突然就给我自动登出了。

自己顶自己顶

Can't sync between different devices. I allready login on Win10. I need login my account on my Mac.But it tould me I have to scan the qrcode with my iPhone Firefox which surport by the Mac Firefox. Then I did it. But my iPhone Firefox told me I didn't use my iPhone Firefox scan the QRcode but use my device camera. Actly, I am sure that I used my iPhone Firefox scan the QR code . I don;t know why. Now I couldn't scan my Firefox .

I think the QR code is only needed when you sync with a mobile device. If you want to use Firefox Sync on a Mac desktop, simply login to your Mozilla account, and you can sync it with the Windows one. For more information, see How do I set up Sync on my computer?, which should be available in Simplified Chinese.

Please try again and let me know how that goes.

This is how I did. It force me to use mobile sync.

From your first screenshot above, looks like you're already signed in into Mozilla account on your Mac.

yes，login allready but couldn't sync. It tole me have to scan the QRcode. So stupid design.

You don't need to click on the Connect another device menu. If sync doesn't work automatically, you can click on the Sync Now button which I highlighted in red in the attached screenshot.

You also need to make sure that your doing it on the other device that you want to synchronize.

you are right. login already, but can't sync data.

Scan fail again. the data couldn't sync. this is my iphone firefox. the mac firefox doesn't be showen.

你意思是iPhone和Mac都登录了同一个账号，但是数据没有同步？ 你要看看同步服务器是本地的还是全球的

试试看这么做： 1 在桌面端登录账号后，打开桌面端Firefox设置，在左侧切换到“同步”，之后点击页面最下面的“链接其他设备”； 2 在新出现的页面上选择“我已经安装移动版”，点击继续，将会出现设置页面并展示出一个二维码； 3 在手机上退出Firefox账号登录（若有，或直接卸载App重新安装），打开手机端Firefox设置，关闭“本地同步服务”，之后再点击上面的“同步并保存数据”。 4 点击页面中的“立即扫码”，扫描前述第二步中出现的二维码。 具体操作过程可参考随附图样。

如果你要用国内服务器同步：国区 App Store 下载的 Firefox 一般都有“本地同步服务”选项，打开它。 macOS 在这里下（注意域名后缀一定是.cn的）：https://www.firefox.com.cn/download/#product-desktop-release （注意登录时也应在.cn的网页完成）

Thanks a lot for jumping in, GuaiZai & copyerder. Really appreciate your help to provide assitance in Simplified Chinese.
