SO easy & SO simple Firefox extension...

Hi... I have a manual task, that I do by hand... very boring :) I want a firefox extension, that will work on my computer only... so no need for fancy icons/graphics... It should automate the task for me. Simple... I copy an address in a web page... then paste it into another form at another website, then change few options in the form, then submit the form and SEE RESULTS! I need the FF extension to do this: - I will select the address. - right click and see my command in the context menu. - something like: send this address - the FF extension will automatically send the address to the form (it's a fixed form in 1 website). - Then will display the results beside the address that I selected/highlighted. So... the idea is to design a FF extension (or toolbar if you want!) that will automatically show me the RESULTS that I was seeing when I manually fill in the form. The form options that I manually enter in the other website, will be pre-selected in the OPTIONS of the extension. So, the default settings, will be set into the extension's options (or if you have easier way, then suggest). Well... just trying to make my life *little* bit easier :) Thanks, Mary
