Firefox 8 breaks MozRepl/RemoteObject.pm

[goldmund]

My script stopped working today right after an update to my Ubuntu 11.04. FF was updated to 8.0 it seems and now I get the following error message:

Transport still not UTF-8 safe: "8.0!"&#65533;"!&#65533;" at /usr/local/share/perl/5.10.1/MozRepl/RemoteObject.pm line 522, <DATA> line 1. (Sub)string is 8.0!"&#65533;"!&#65533; at /usr/local/share/perl/5.10.1/MozRepl/RemoteObject.pm line 252, <DATA> line 1. garbage after JSON object, at character offset 4 (before ""\x{fffd}"!\x{fffd}") at /usr/local/share/perl/5.10.1/MozRepl/RemoteObject.pm line 240

To make it simple I reduced my script to the following and still get the above error message:

#!/usr/bin/perl
#

use strict;
use warnings;

use LWP 5.8;
use WWW::Mechanize::Firefox;
use Net::Telnet;

my $mech = WWW::Mechanize::Firefox->new(launch => 'firefox');
my $url = 'http://www.google.com';

$mech->get($url);
print my $response->content;

Since perlmonks was where I found the solution when FireFox went to 7 (http://perlmonks.org/?node_id=926820) I figured this was the place to seek a solution.

It's not MozRepl::RemoteObject that's broken but the mozrepl Firefox Add-on. You need to use a checkout from the Github repository (for example 1.0.2). You could also have searched this site - there is at least one other post with the same problem and same solution.

Update: RemoteObject.pm fails in open firefox8.0 is that other post, as found by Super Search

Thanks for the prompt response, everything running smoothly again.
