I'm running Firefox 55.0.2 under Kubuntu 14.04, and I'm having persistent memory usage problems. Most recently, something called "Web Content" (as revealed by top), is using a huge amount of memory. What might that be, and how can I shut it down?

Assuming you are using the release version of Firefox and "web content" process is referring to one of the content processes of Firefox, my question would be: are you using an ad blocker, such as uBlock Origin? I have noticed that some ads delivered over the advertisement networks to websites tend to cause Firefox to go wild on cpu and memory consumption and right now the only work-around seems to be to block them.
