Everytime I click on the LastPass browser extension icon in Firefox, and then click on the "Account" button, and then on the "Account Settings" from the pull down menu that opens up, it just throws me onto a new blank page within Firefox. MyLastPass extension plugin, Firefox browser and operating system (Windows 10 Pro 64-bit) are all up to date, and I have disabled all other browser extensions. I'm using a free LastPass account i.e. I don't have the Premium Subscription.
