Firefox: форум сообщества

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?

Starting last night, Microsoft wants me to login with my username and password. However, it will not allow me to input those factors. I have Windows 11 and am using a new desktop cube made by KAMRUI. I detest the control Microsoft is forcing on me. Can I delete my MS account? I don't use their products. Also, I am disgusted by their manipulation and invasion of my privacy. What are my options, in this case?
