Useful for a support ticket, and useful for seeing how much a page knows about you by default.

Frequently asked questions
Why does my user agent mention browsers I do not use?
For historical reasons every user agent string claims to be Mozilla, and Chromium browsers also mention Chrome and Safari. The string is a museum of compatibility hacks, which is why browsers are gradually freezing it.
