I found NoScript to be a good alternative. It disables JS by default but then you can reenable per page but also per domain. You only enable just what you need for the page to work and sometimes only temporarily. I still need to enable things here and there but it's a fairly easy straightforward process. Couple this with uBlock and firefox Container (where I am logged to google only for gmail in a specific container) and the web is pleasant again
