Last Pass extension from your website not working.
Last Pass Firefox extension was working on my Windows 10 computer until 3 weeks ago. Now when I click on extension it hangs. (the extension is red red in tool bar so I know it is correctly installed).. I was able to solve by deleting Firefox extension and instead installed Last Pass 4.0 directly from Last Pass's site. Please fix your extension. This is not a Last Pass issue.
