Works fine until a few days/weeks after installation. Then it stops working altogether (on Windows 10 anyway). Same experience in Firefox as in Chrome. I've been a paying Lastpass user for years now, and never had any problems until a few months ago. Only thing that (temporarily) solves the problem is removing and re-installing the extension, but the problem re-occurs after a short while. Last time just days after re-installation. Have submitted a request to LogMeIn, Inc., but I know from experience they are tediously slow in responding.
