Can't sync my data

more options

Hello.

I have been using firefox for a quite while now, I have LOTS of critical data linked to my firefox account (all the passwords, important bookmarks for work, etc)

I completely formatted and reinstalled windows on my pc because it had software issues that made it impossible for me to use my pc, after that I installed firefox , but forgot password for my firefox account, so I reset it with my mail, but now I can not sync to my very important older data that I desperately need.

Is there any way I can recover my data? Please, it is very important for me.

you can check that all the activities happened from same IP address, and that I searched for "windows 7 iso file" using duckduckgo right before I requested password reset


thank you in advance.

Resetting the sync password, or changing its e-mail will remove all data from the servers.

Resetting the sync password, or changing its e-mail will remove all data from the servers. The username and password are used to create the encryption.

This is a security feature. https://support.mozilla.org/en-US/kb/ive-lost-my-firefox-sync-account-information

Note: Only the data on the servers is cleared. The profile data is not changed or removed.

Do you have a backup? Or is the data loaded in another system or profile?

Thank you for your replay.

I don't think I have backup. only place I had my data loaded is on my pc, on which I reinstalled windows which resulted in formatting everything, including firefox browser. when I re-downloaded browser and tried to log in to my firefox account, I forgot password, and asked for reset. would that delete all the copy's of my data?

if not, I'm ready to answer any question regarding that account, to prove that I'm the same user. I can provide information about websites on which I had saved passwords for, name of bookmarks, etc.
