Firefox Community Forum

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

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.

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?

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.

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.

Emergency!!! I just arrived home from a trip, and on my primary pc, I had saved say 50 tabs over a number of years. I was/am interested in syncing, but I had taken no known actionable steps to do so - but when I arrived home, my primary pc did not open the previous session. I lost everything. Spent hours trying to recover the previous session. Then, I simply decided to go back seven days and restore those tabs. Eight Hundred(!!!!!) tabs were restored, from what appears to be from each of my computers. I am now deleting the 750 unnecessary & repetitive tabs (again, on my primary computer), I am now *scared to death* to boot any of my other computers and have all of my history wiped again. WTF!!!??? Thank you very much!!!

Until few days ago i could see all the opened tabs of my first phone on pc using "Tabs from other devices" option. Today i connected another phone and now i canno't see anymore tabs from my first phone. At the moment i don't have access to the first phone as i had to rapair it. Under my mozilla account i can still see my first phone connected.

I have a desktop and a laptop on firefox. I am selling my laptop so i cleared history and deleted all bookmark history.

To my horror, even though i remember i have signed out of mozilla account on the laptop firefox, on my desktop firefox all the bookmarks including bookmark folders are gone. Thankfully, i have a fairly recent backup of firefox userprofile file so i restored them.

However, to my horror once more time, I realize now firefox sync automatically deletes my bookmarks everytime it syncs so i have to turn it off.

How can i make firefox sync to treat my current bookmarks as the latest and stop deleting them?

I am positive that I've been signed into a Firefox browser account for the past several years (to Sync my favorites, etc.) However, my laptop recently crashed and, when I signed into my Firefox account on my new computer, the bookmarks that populated are YEARS old. I'm not sure how this happened. Can anyone help?
