Type about:customizing<enter> in the address bar. Look for Show / Hide Toolbars at the bottom left.

There is also a Restore Defaults button at the bottom middle.

Googlebar Lite still does not show up on the menu bar.

Was it listed in the about:customize window?

Is it active in about:addons?

Googlebar Lite shows up in the customize window and is active in the add-on's. It is checked as one of the toolbars in the View Menu, yet is still not visible on the menu bar.

Type about:customizing<enter> in the address bar. In the new window, look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but some icons are locked in place.

Thanks. I moved it to the menu bar. Not in the same place as before, but it's there, so thanks very much. Hope it won't disappear again.

If it does, you know what do do.

Glad to help. Safe Surfing.
