2021-09-06 Sam Tuke Works mostly as described. Unfortunately it doesn't seem to support wildcards (*) in url patterns, meaning eg every subdomain of a given parent domain must be listed separately, which is not convenient.

2021-04-11 Cyberknight Very awkward to use. It can't be activated for the current Page/site, but, instead, its address must be manually added to the list of the desired agent string, what is possibly the worst way to implement it (what if a site matches more than one list, the first string is selected or does it randomise amongst all matches?) I also had problems using * as a wildcard, forcing me to use full URL.
