I don't see the pic either. More sun is the only cure for leggy. You can cut off etiolated growth, but without more light, the new growth will be the same.

There are many, many threads and photos about jades on Cacti & Succulents forum...

Hi! Becoming top-heavy is pretty normal for a jade plant because it’s best to keep them in smaller pot so you don’t accidentally overwater them or ror the roots. The trick I learned from someone else is to take the pot it’s in and place within a larger pot so it’s heavier and keeps it from being so top-heavy. Hope that helps.

Agree. Leggy & top-heavy can happen simultaneously, but are not the same @ all. Leggy = etiolated. Top-heavy is merely having more weight above the center of gravity than below, whether etiolated or more compact.
