How many times have you wished you could paste more than a single line into a search box or form in your browser? Well, now you can thanks to this very quick Firefox hack. Actually it is not a hack at all it is just a settings tweak.

Okay. So, open a new tab in FF (Control T), go to the address bar (Control L) and type about:config and hit the return key. Filter the config page that appears using the keyword “singleline”. You should see just one entry:

editor.singleLine.pasteNewlines.

Double click it and change the value from 1 to 2. If it’s already 2, then you’re already done. Now, you should be able to paste two lines from your clipboard into a Firefox search box or form even if the website displays only a single line. Very useful if you want to search for a text snippet that has had a linebreak inserted by an email program, for instance. But, there are many other times when you will find this tweak indispensable.
