WebThumbnailExtension Web Content High CPU/Memory Usage

Just wanted to post that the solution here worked for me -

Looks like Quick Look is the culprit, and I never use it, so this was a pretty painless bandaid until they patch it.

Open System Preferences > Trackpad > Point & Click, and uncheck "Look up & data detectors."

At the moment, the only solution I found is to close Safari, "Force Quit" every instances of "WebThumbnailExtension Web Content" in Activity Monitor, then use other browsers (e.g. Chrome, Firefox, etc.).

Same issue. Please help.

the same issume，please help us

I came here to add that, while this has solved the problem for me about 80% of the time, it's still happening sometimes, and I don't know why. I think it might be tied to MS Office, but I have no idea how to confirm that, because it happens at random times.
