Well, that is one clientid for one Thunderbird version of my four
versions of Thunderbird on Fedora. If they have my name, address and
phone number they are welcome to it.
I think it would identify my Thunderbird version, but have they would
have no idea who is using it.
If enough unique id's have the same crash, use the same features or
don't use the same features the application's can be improved.
I hate it when something I use is removed or changed because I'm in the
0.000001% of users. 😞
