Hi, I have been wanting to switch to Firefox for a while now and I have imported all of my data from Chrome onto Firefox. All the other members of my household use Firefox on their Mac laptops and iPhones. I have only ever signed into my own account on Firefox, and in the same way I have only ever signed into my own account on Mozilla VPN, which I have used for over a year while living elsewhere and have never had a problem with this. I also have only my own Google account in the data imported from Chrome. I have no one else's information for any account on anything in my device nor, to my knowledge, do they have any account information of mine on theirs. However, sometime in the 10 or so months since I imported my Chrome data - around the same time I moved into a house with others who use Firefox - my laptop's Firefox seems to have...connected somehow, in a way atypical with normal syncing, with the other devices in my house. Occasionally, when I open Firefox on my computer, whatever tab another household member has open on their computer will open instead of a homepage. Also, a little icon pops up occasionally to tell me Firefox is "open on iPhone" when another household member is using Firefox on their iPhone. I use an Android which does not have Firefox installed, so it's not a glitch syncing with my own device. I do not know how this happened and I do not know how to stop it. There doesn't seem to be any evidence of this connection in any place I can see in the preferences window, nor can I find any way to permanently unsync my device's Firefox application from anything unless I sync something first. Any ideas? I'm not that terrible with computers lol, I swear!
