I’ve used it off and on in KUbuntu for a couple of years without issue, installing the helper app from the .deb file directed to me by the plugin. I have scanned it for viruses and watched for strange behavior, and I haven’t observed anything suspicious. It runs as the current user, no elevated privileges required.
In the suburbs of a middle-sized city in Ohio, USA. So midwest, but a bit older, higher-density, and more northeastern suburban layout than, say, Iowa. Built up in the 1960s-70s. Almost all single-family suburban homes on large lots.
