Hi. I was using 32 bit Windows 7 until this morning. I formatted my laptop and installed Windows 8.1 x64.

I installed firefox and login sync with my account but sync didn't bring back my informations. I reset my password and tried again but result was the same.

I have Sync recovery key so i tried this: I tried to go to firefox > options > sync > set-up sync > i have an account > i don't have the device with me in order to link firefox to your existing account option, but there is only "create a new account" and "log in" options. There is no option to use recovery key. Please help me. I can't get back my bookmarks, passwords and extensions.

hello Atikun, firefox 29 and upwards is using a different sync system which isn't compatible with accounts set-up in older versions.

in this case you'd probably have to use a workaround and download the prior firefox version, disable automatic updating for the moment (in options > advanced > update), link it to the old sync account and upgrade after you have successfully restored your data this way...

Hi. Thank you so much for your help. I installed firefox 28 without deleting firefox 29.0.1. Then i used my recovery key and login info on firefox 28. All my information came back. Then i went to Help > About Firefox and firefox updated itself to firefox 29.0.1 again. No problems left at the moment.
