I cancelled my LastPass subscription and removed LastPass forever. They dumped their Firefox support long ago and haven't updated this extension since forever. For a long time I've experienced very slow Firefox performance, and not only that, but my whole PC would freeze almost every day, causing me to hard reset. All that was due to LastPass extension. As soon as I removed it, Firefox became WAYS faster and my freezes finally stopped. Please abandon this for good. BitWarden is way to go.
