Lastpass used to be a great tool, and I've subscribed to the service for years, but it no longer works in Firefox for Android. Can't get it to log into my Lastpass account. After entering my credentials, the cursor icon just spins indefinitely. In FF 57 for Windows, I also encounter problems, such as it often not prompting me to save new credentials or to fill in existing creds. The fact that the subscription fee doubled but the quality of the product deteriorated means I'll no longer be subscribing. Too bad because this used to be a frustration-free product.

Update: According to Lastpass support as of January 31, 2018, Lastpass will no longer be supporting their addon for the Android version of Firefox and suggests using another browser. Oh well.
