Why can't WWW::Mechanize::Firefox locate it's "new" method?

I get the following error when I run the little sample script:

Can't locate object method "new" via package "WWW::Mechanize::Firefox" (perhaps you forgot to load "WWW::Mechanize::Firefox"?) at mechtest.pl line 2.

use WWW::Mechanize::Firefox;
my $mech = WWW::Mechanize::Firefox->new();
$mech->get('http://google.com');

$mech->eval_in_page('alert("Hello Firefox")');
my $png = $mech->content_as_png();

I have WWW::Mechanize::Firefox installed, I have the MozRepl plugin installed on Firefox. Why can't it find new?

Most likely you are on Windows and have an old version of WWW::Mechanize::Firefox installed. That old version was at the time (badly) named Fire_F_ox (note the upper case F). Look whether you have a file FireFox.pm on your machine.

Windows has case-insensitive filesystems and hence will happily load a file FireFox.pm even if you request to load a file Firefox.pm.

The solution is to uninstall WWW::Mechanize::FireFox and to install WWW::Mechanize::Firefox. Also, for future reports, it immensively helps if you tell us the version of Perl, the version(s) of the module(s) and the OS you use.

The module requires some dependencies like MozRepl::RemoteObject etc. you should probably reinstall using cpan or ppm (if using ActiveState) etc

Sounds like WWW::Mechanize::Firefox isn't installed properly. Reboot and confirm that it's installed properly (cpan, ppm etc).
