In the ArcticFoxie versions, you can add any useragent you want in the loader.ini file.
At the end of the Parameters line, the below is what I add, you could change this to whatever useragent you prefer:
--user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36"
