I was a long-time user of Lastpass before I started using Bitwarden a couple years ago, and I'm never looking back. The philosophies of Bitwarden, including it's commitment to it's open-source code and cost-free status, give me a much greater sense of security than the other ready-made options. As far as this extension goes, it is a godsend, given it's seamless operation inside Firefox. Due to the ever-increasing attacks on privacy, I finally did my little part in purchasing Bitwarden Premium because why not support a company that keeps me safe? Thank you, Bitwarden!
