@FastSpace So we just need to apply a new fingerprint according to the browser version of the current BAS (e.g. 26.2.0 --> Chrome 117) to the profile and the rest should be fine in terms of anonymity?
Just noticed that the "LastVersion" file in the profile folder, as the name suggests, gets updated when the profile is opened with (another version of) BAS e.g. from 114.0.5735.91 to 117.0.5938.63. Therefore it's not suitable for our need to determine the original version of which a profile was created.
But at least can be said what was the latest BAS version that worked with it ;)
