Facebook recently rolled out a new change to their user interface where they got rid of the Comment button and allowed users to comment by hitting the Enter key. However, this was a bit annoying to users who did not know about it and innocently hit enter to add a new line to their comment. When they did this, the comment was automatically posted. (Hint: use Shift + Enter to add a new line)
If you are someone who has been annoyed by this problem, there is a quick and easy fix to get back the old comment button on Facebook through a Greasemonkey script.
To get the old comment button back in Facebook, head over to http://www.crypticide.com/alecm/chrome/ and click on the FixSillyFacebook.user.js to install the Greasemonkey script in Google Chrome and Firefox (you will need the Greasemonkey add-on). If you are using Opera or Internet Explorer or Safari follow our earlier post on Installing Greasemonkey scripts in Opera, IE and Safari.
