I would advise people to be careful with plugins/extensions/add-ons. Add-ons are risky, they bring more attack surface, and you add yet another party you need to trust add-on developer. Before installing add-ons, think about the following: What does the add-on do and what is the impact of it? Who is the developer of this add-on? Is said add-on open source? Does the benefit of add-on outweigh the con of extra attack surface, and adding another party to trust.
