I've just noticed that when Firefox on my Leap 15.0 system, which currently says it is 60.3.0esr (64-bit) in the Help/About, tells web servers that it requests pages from that it is
"Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0"
Why does it lie about its version number?
It does no lie maybe? By the principle of data parsimony, why would you give information that shall be available to the owner of the system but is of not use but tracking to the outside site? If it is sufficient for a correct service to know the general version and not the sub-revision, then this behavior would be perfectly sensible, also from a security point of view. If I do not know a revision, i have trouble to attack a precise revision. Besides, AFAIK you can even force a browser to give an arbitrary indication to web servers to heighten privacy and to make tracking harder. So that would not be a lie. But I am just guessing.
Thanks, that's a very reasonable explanation. I wonder if it's correct? Why don't you check out with your browser the following amusing and also educating page:
