ohhhhh you betcha. https://amiunique.org/ https://amiunique.org/ i ran this on my work laptop (windows 10 / firefox - mostly default settings). the "details" tab shows a full breakdown of each fingerprinting component with a "similarity ratio" (percentage of fingerprints that share the same value). every entry is 20% or greater, most of them around 50% except for timezone (4%), canvas (1%), and user agent (0.12%). so, yeah, user agents are still the largest source of entropy by a wide margin for fingerprinting scripts.
