Q:

window.googleapis is undefined

I am trying to add a G+ +1 button on my web page. I am following the steps provided on Google developers page, but I get the following error window.googleapis is undefined. The same error appears even on Google developers page (viewed in Firebug).
Why does this error appear?
And how can it be solved?

A:

Looks like this error will appear only if the firebug is opened. Close firebug and refresh the page

A:

I could reproduce the bug on Firefox 18.0.2 + Firebug 1.11.1, though as I said before not on Firefox 19.0 (with the same profile).
So obviously this was fixed in Firefox 19.0. If someone still sees that issue with that Firefox version, please comment at issue 6280.
