What are the limitations and compatibility?

  • Not available for Chrome OS
  • Not available for Opera 12 on Mac OS X. We believe this to be a bug in Opera 12 for Mac OS X.
  • For Opera, the Preference option "Enable plug-ins only on demand" must be disabled.
  • For Mac OS X 10.10 (Yosemite), the LastPass Menu Bar must be enabled. To enable the LastPass Menu Bar, go to Safari View > Show LastPass Menu Bar after installing.
  • If you are experiencing issues with the binary component disappearing in Safari, be sure that "Stop plug-ins to save power" is disabled by going to Safari Preferences > Advanced.
