Are you talking the site or Addon issue?

I have lastpass vault in a toolmarks tab. When I close my laptop and the open it I get a message lastpass is being signed out and I am presented with the laastpass login page. I would like not to be signed out of lastpass when I pause working or close my laptop.

thank you for your help

I assume this isn't just a matter of the session timing out due to inactivity, or reloading the tab (Ctrl+R), or Firefox closing and relaunching. Instead, the page seems to somehow be detecting a change in the system state like sleep or hibernation (or hybrid sleep) mode?

Also, you mentioned toolmarks, I'm not sure what that is.

toolmarks was a typo. I have bookmarked my Lastpass vault. When I click the bookmark to access my vault, it presents a message"'signing you out of lastpass." and then displays the Laspass sign in page.
