I have a Firefox add on called "Paste Email Plus 5.1" which allows you to paste email addresses into any text field. It is a great add on and I use it a lot but today it stopped working. I click on it and nothing happens except the appearance of a tiny white square under the lower left corner of the icon on my toolbar. Previously, when sending an email, I would click the "Paste Email Plus" icon and a drop-down menu would appear with the names of my contacts. I would click on the name of the person I'm sending the email to and it would appear in the address field, eliminating the need to type in the address. I hope someone has a solution to this problem because I really like this add -on. PS. My "Add This" add-on stopped working months ago and I can't get it back either.
