Rated 5 out of 5 stars

Does what it's supposed to for Gmail (Yahoo s---ks anyways. Five stars because it's the only quick page-emailing add-on that (brilliantly!) includes your selected text in the body of the email.

FYI fellow FF users. RTFM! Stop asking questions about it in the rating comments. I hate when a good add-on like this gets under-rated because of nit-pickers and lazy folks. Here's an example of writing a REVIEW, as it's intended:

"Email This! does not provide a large plethora of options. While this may be a drag for some FF power-users, it complements the simplicity of this add-on (how complicated should sending an email really be?). After installation, using this add-on was very simple and intuitive. Select my text of interest, right-click, and select the email service I want to use. Too easy!

While I might suggest that the author consider filling in a few extra-small details (a configuration option for setting a default "To" address, for example), this is still the most effective, instant-page-emailing solution that I've found for FF yet."

It's not difficult, FF fans. Try it sometime.

This review is for a previous version of the add-on (2.2.6). 

Stevo,

Thank you for the kind words and the example 'review'! The add-on is now at 5-stars again, so all is well in the world! I tend to request (from Mozilla) that all bug/support comments to be purged from the ratings page, but sometimes it takes a while to act on it.

If you're looking at a extension with a pre-filled To: line, check out my other extension, Email Yourself!

Have a great day!
