Description:
Facebook Mobile Timeline Cleaner. Take back control of your Facebook Timeline with this activity log scrubber! This script deletes your facebook comments/posts/likes etc. 
This works on  https://m.facebook.com/<yourname>/allactivity and bulk deletes, hides, or unlikes
content to clean up your facebook. To use it, install greasemonkey on firefox or tampermonkey on
chrome. Then navigate to your activity log page (profile -> "View activity log"). If the script
is working it will add a new button call Open All Time, just after "Friends". Click this and many
tabs will open and begin deleting, hiding, and unliking.

Sometimes the script freezes and needs to be rerun, fix this
