Browser can't log in to sync but accounts.firefox.com works perfectly
Today I found that my sync is disabled (it works at least 2~3 months ago)
I click "enable sync" but it just said "working" or something (not sure what exact word it is in English version, the original text is "正在开启同步...")
Then I found a answer at this site said quit and login again might fix the problem
...then I can't login anymore
When click "login" in about:preferences#sync , it jumps to https://accounts.firefox.com/signin?action=email&service=sync
I login to accounts.firefox.com successfully and found the device I'm using (fde 92, check attachment 1)
But the Browser is still not logged in (check attachment 2)
I tried:
- Reset pref.js & user.js
- Delete /weave/ folder
- Disable all addon
- Delete device in accounts.firefox.com and login again
- Delete /startupCache/
None of them works
Any help?
