Diễn đàn hỗ trợ Firefox

I returned a phone that I had for 2 weeks (the phone was a Motorola G Stylus 2024, if that's even relevant), and while I did a factory reset on the phone before returning it, I am worried that my Firefox account information is still accessible through the device.

One reason why I am worried is because, when looking at synced windows open, *everything* that I had open on there was open and accessible through my account. Another reason that I am worried is because I did not log out on the device before returning it to my local Best Buy.

It'd probably be impossible to track down the exact phone that I had, but can anything be done? Should I redo my log-in password for Firefox (or even all the sites that I used on that phone) or am I worried over nothing?

Sync instructions on desktop browser include: Sync Firefox on your phone or tablet 1. Open Firefox on your mobile device. 2. Go to the menu ( on iOS or on Android) and tap Sync and save data 3. Tap Ready to Scan and hold your phone over this code

There is no "Sync and save data" that I can see on menu

I'm on Firefox mobile, and I keep having this issue, and trust me, I've searched for solutions, but they just haven't worked out. Wverytime I open the Firefox app, it asks me to "get started". I've had Firefox for nearly a year now and it's my default browser. The only thing I can think that could be causing this issue would be me recently syncing my account onto my computer, but that was a little while ago and it used to not do this every time. Now it is. Please help?

Running Win11 on desktop PC. Sync option offers QR code to scan but Firefox on android does not have sync scan option on settings. Despite instructions to contrary, that option is not listed on mobile. Yes I'm logged in and yes I have synced previous versions of firefox
