I have tried on Edge, Chrome and Firefox. When I log into my LastPass account and the browser does not have the extension installed, a red spinner is in the middle of the screen and my entire page is greyed out.
Clicking around, scrolling, hitting escape, hitting refresh, nothing works to clear the spinner. I am unable to access anything. In fact when I hit refresh, it wants me to log in again but in the top left hand of the login page it shows me logged in.
I do not want to install the extension. I want to use a computer to log into my account from anywhere in case I get stuck, lost my phone, etc. So it may be a friend's computer or let's hope never a public computer.
Thanks for the help!
