I have tested Like Box in all modern browsers and scrollbar does show.
I can not make any changes to Facebook Like Box because code displayed inside my module is generated by Facebook. It can be only configured with available options.
If you have still missing scrollbar then you should report this to Facebook Developers.
In my opinion, this plug-in is a must have on any joomla site using JS. I only had a minor conflict on one page but I couldn't fix it... so I downloaded this extention, installed, and configured it in literally 30 seconds and 'everything' on my site now
1) works as it should
2) seems to work much faster
I would recommend this extention to anyone to everyone... absolutely fantastic!!
Thank you for the review :-)
