Sometimes Chrome will automatically hide extension icons. Here's how you can have the LipSurf icon show in the toolbar again:
Click the Chrome Menu (usually three dots "..." on the upper right of the window)
The LipSurf Icon should be at the top of the submenu
Right-click the icon and click "show in toolbar"
If you don't see LipSurf there either...
Make sure it is installed and enabled in
chrome://extensions (type this in the address bar)
