1. After composing mail in Yahoo mail on my Mac laptop with Firefox, I cannot scroll down to "Send" to send the email I can Send using Safari on the same laptop,. 2. On the Website Sense.com, Firefox has changed the background. The original is baqlck background with yellow text; Firefox displays White background with blue text. Safari displays the original on the same laptop. I've been using Firefox since 2000, please stop tinkering with pages which work. I'd prefer to continue using an Open Source outfit rather than a Proprietary one, in solute of not having a Help phone number. ThANK YOU.
