Sometimes you posts a wrong status in facebook and later need to modify or delete it. Facebook Undo extension gives you a 5 sec of interval time on each facebook posts. Do You Know 'undo Feature' In Facebook Benefits of using this Facebook Undo Extension: ✔ Posted a status and changed your mind? undo your post within five seconds. ✔ A post that you undo using this extension is never published (so Facebook will not be logging your status. Facebook is known to save your data even if you delete it). ✔ Without the extension, simply deleting a status on Facebook does not work fast enough for people not see the original post - the status might still be shown on your friends' feed for a couple of minutes (because of Facebook caching mechanisms). #Facebook #FacebookUndoFeature #Extension #Feature #Trick #Tech #TechTrick
