I have two computers. I logged into my account on each. However now the bookmarks are different on each computer. Completely rearranged. Also, the banking window had it's own logins and passwords, but now they are all intermixed. I just want it to work the way it did before.

Unknown Microsoft Login Appearing in Saved Passwords

Hi,

I recently noticed an unknown Outlook/Microsoft account (oliveconscious13@outlook.com) saved in my Firefox logins. The email and password appear to be randomly generated, and the account’s preferred language is set to Russian. I have never seen or used this account before.

Here are the key details:

My Firefox account was created on June 8, 2025.

The unknown Microsoft account was created on July 8, 2025.

I only have two devices connected to my Firefox account: my Mac (where the account first appeared) and my Windows PC.

The account is also showing up in Chrome’s saved passwords, which I never intentionally synced with Firefox.

This is a brand-new Mac purchased directly from Apple, so I know it wasn’t a used device.

I’m trying to figure out:

How this account was added to my saved logins.

Whether this was synced from another device.

If there’s any security concern or if my account may be compromised.

Could you check my sync history or logs to see which device added this login, and advise on how to make sure my saved logins are secure?

Urgent: Lost Firefox Sync Data after windows reinstalation

Hello Mozilla Support Team,

I hope you can assist me with an urgent issue. After reinstalling Windows on my PC, I lost access to my Firefox Sync data, which includes years of bookmarks, saved passwords, and browsing history.

Before formatting, I had been using Firefox Sync with my Firefox Account (sometimes signed in via Google). However, after reinstalling Windows and logging back into Firefox Sync, my data no longer appears. At one point, I saw my account showing activity from just before formatting, but now that is gone as well.

I am worried that my synced data might have been overwritten or lost during this process. Unfortunately, I do not have a local backup of my Firefox profile.

Could you please help me: - Verify if my Firefox Sync data is still stored on your servers. - Assist with recovering my synced data or advise on next steps I can take. - Provide any guidance on preventing data loss in the future.

Thank you very much for your help. I look forward to your response.

Best regards.
