Any update here? I continue to get "This webpage is using significant energy. Closing it may improve the responsiveness of your Mac." on every FT page after about one minute. I don't have this problem with Chrome or Edge, but it's consistent on Safari. Thanks.

That condition occurs occasionally on my MacBook Pro using Safari. One of the culprits seems to be "Disnoted".

When you get the significant energy message, check the Activity Monitor. If Disnoted appears select it and Force Quit. After a while, the fan slows down and things return to normal. Quitting Disnoted does not seem to have any adverse impact. It will return in a few days to repeat the cycle.
