cannot drive existing profile

[stuart-little]

I am running the following, after having created a throwaway new profile called throw:

#!/usr/bin/env perl
use warnings;
use v5.12;

use Firefox::Marionette;

my $url='https://www.google.com';
my $firefox = Firefox::Marionette->new(
    profile_name => 'throw',
    visible => 1,
    )->go($url);
sleep;

This opens up a browser window on the default startup page Firefox gives new profiles (screenshot here), but hangs there.

It never reaches google.com, and pegs one of my CPUs to 100%.

Edit

Actually, it hangs even without the sleep; directive at the end. Removing that last line makes no difference.

Nor does setting my profile's homepage to blank. If I do that, then running that script results in a window hung on that initial blank page (again with a 100%-spinning CPU).

Here's what I get when running the following command in a clone of this repo:

$ perl -Ilib -MFirefox::Marionette -e 'my $firefox = Firefox::Marionette->new( debug => 1, visible => 1, profile_name => 'throw'); ' 
** firefox --version
** firefox -marionette -safe-mode -P throw

And it hangs there, again spinning up a CPU to full throttle. I have to kill the process with Ctrl+C.

I've also checked that running just that last hanging line in a terminal, on its own, without invoking Firefox::Marionette, works fine:

$ firefox -marionette -safe-mode -P throw

This opens up a Firefox window and does not hog a CPU. I can also visit web pages:

$ firefox -marionette -safe-mode -P throw 'www.google.com'

starts me up on google, again with no excessive CPU work.

Ok. I've verified this one. Bit busy at the moment, will get to it on the weekend.

Thanks! Some more possibly-related info follows.

I've also tried to use a copy of the existing profile instead, passing profile instead of profile_name (as per the documentation). So:

perl -Ilib -MFirefox::Marionette -e 'my $profile = Firefox::Marionette::Profile->existing('throw'); my $firefox = Firefox::Marionette->new( debug => 1, visible => 1, profile => $profile );  $firefox->go("https://www.google.com");  '

This again hangs and fails to load the google page (it just freezes on a blank page), but with more complaints:

** firefox --version
** firefox -marionette -safe-mode -profile /tmp/firefox_marionette_local_uMOkW5MQKkw/profile --no-remote --new-instance

/tmp/firefox_marionette_local_uMOkW5MQKkw/profile/prefs.js:237: prefs parse error: integer literal overflowed

I am having no trouble basing a profile off of this one with Python's Selenium Webdriver, via its firefox_profile option. So I don't know why prefs.js would pose a problem if I try to peruse it through Firefox::Marionette instead..

Just committed a fix for this. Can you confirm this fixes the issues in this bug?

[stuart-little]

Yes, that did it. I

• removed the existing profile's cookies.sqlite
• ran the following command in the repo directory

  perl -Ilib -MFirefox::Marionette -e 'my $firefox = Firefox::Marionette->new( debug => 1, visible => 1, profile_name => <PROFILE-NAME> );  $firefox->go("https://www.google.com");  '

• checked afterwards that a cookies.sqlite file was left behind, containing google cookies.

So yeah, this seems to have fixed it, and I think it's safe to close this. Thank you!
