I should add that there are ways to detect and work around these situations, of varying levels of difficulty and specificity*; if there's sufficient motivation I can flesh out a bug.
* E.g., using server timestamps to detect whether another client is racing with us, and deciding that a profile copy must have occurred, at which point we can prompt, automatically rename ourselves, try to figure out which device was the original, etc.; and/or trying to use OS or device information to fingerprint and detect cross-machine profile copies. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
