Everything the browser reports about itself, on one page — the details a support technician will ask for first.
Reading browser details...
The details come from the browser’s own user-agent string and navigator properties, read locally — nothing is looked up or sent anywhere. The user-agent string is the same identification the browser presents to every website it visits.
Why does my browser claim to be several browsers at once? User-agent strings carry legacy names for compatibility — a modern Edge or Chrome string mentions Safari and Mozilla too. The checker reports the real browser by checking the distinctive token first.
Is this information identifying? On its own, no name or account detail is shown. Combined with other data points it contributes to a device fingerprint, which is why the full string is shown here — so it is not a surprise.
