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.
