Did you ever want to text yourself? You're headed out the door to some place you've never been before, so you dutifully looked-up the address and driving directions on Google Maps. It would be handy to send yourself a text message with that info in it, so that you don't have to drag along that printout of the directions.
Google Send To Phone is a Firefox extension that allows you to send SMS messages (text messages) to your mobile phone from within your web browser. Copy and paste whatever content you want from your page into the "text to send" field. If you're going long, the tool will automatically split your text into multiple messages.
Not only is this useful for texting yourself, but if you need to dash off a quick note to somebody else, you can do so as well. All you need is the phone number and carrier for your recipient.
Google Send To Phone is compatible with any system running Firefox version 1 or later. Sending messages through this extension is free, but charges may apply to receiving them; check with your carrier for details. Most major carriers are included in the list for sending.
