Hi, Linked Firefox Sync accounts that are no longer in use--or useable--still appear in the synced tabs drawer in Firefox for Android as different groups of tabs under corresponding device names. This is despite trying to fix the issue by changing the account password from one device (PC) I still use and deleting my account/setting it up on Firefox for Android again with the new password. It seems Firefox for Android (or the Firefox Sync system generally) syncs tabs from offline devices linked to the same email address, despite them not being set-up using the same password. Whether this is by design, something not anticipated or just a bug, it makes it very tedious to scroll through the list of tabs from unwanted "devices" (actually, previous Firefox installations on my current PC, wiped along with entire drive during system reinstall) in order to find tabs directly under the device name corresponding to the current Firefox installation on my PC. I'm prepared to delete the entire account and de-associate all my devices at once, and start fresh, but that doesn't seem to be an option.
