Script not letting facebook do its job.
I feel like I have read all the other questions related to this kind of problem, but I still haven't figured out a way to make it work. I have reset firefox, I have done the plugin check, I have installed the YesScript addon and I have tried the safe mode and... no change. My problem is that whenever I open Facebook, Mozilla is "not responding" for a few seconds and then, this message appears:
"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."
Script: https://fbstatic-a.akamaihd.net/rsrc.php/v2/yn/r/pk3wlFysxy7.js:34
How can I stop this? If I close the warning box, I can't scroll down the news feed, can't press on some buttons, etc.
