Lastpass not working properly on Firefox - cannot open my vault.
I have been using Lastpass with Firefox for a couple of years with no problems. But recently I ran into an issue and need help. I can log in to Lastpass and it will automatically fill in passwords as it should; however, when I click on the Lastpass icon all I get is a white box -- so I cannot open my vault. I think this happened after the last Firefox update but am not sure about this. Any ideas?
