I don't touch Chrome, so I have no experience with it, but there is an extension for that browser called WikiTreeX that "enables you to create and edit WikiTree profiles using data from other genealogy websites" (
https://www.wikitree.com/wiki/Help:WikiTree_X).
Also, while it's not an import per se, there is a tool for linking WT and FS profiles. Easiest way to find it is to go to your Watchlist; it's toward the middle of the top bar of tools/links ("FS Matches"). There's an element of chicken-and-egg, in that the tool will not find matches if there isn't enough information entered on WT, but once there is a link, there's an "update WikiTree" button that will allow you to bring over any new information from the FamilySearch profile.
(There is a way to manually create a link between profiles, for those inexplicable cases where the matching algorithm fails to recognize someone; I don't know if/where there's a link to it anywhere else, but it's on the Help page that you get by clicking the tiny blue question mark on the main matches tool's page.)
