I've been using LastPass (free version) for years and was always satisfied with the functionality. However, LogMeIn announced on 16/02/2021 that they will effectively cripple the product I use as of 16/03/2021, by arbitrarily preventing sync between desktop and mobile.

Given this, there is no way to guarantee that even the new, reduced level of functionality will remain going forward. In my opinion an app like LastPass derives its value wholly from being reliable into the future. Therefore, the extension is useless at best.
