Firefox extension and toolbar button

I'd like you to embody the Zoho bookmarklet into the firefox extension, so that

a) instead of, or in addition to the 'bookmarklet', the same functionality is embedded in a toolbar button (i.e. the main toolbar NOT the bookmarks toolbar).

b) the same functionality, pasting text from a web page to Zoho, should also be carried out through the context menu.

In short. I do not use the bookmarks toolbar to save screen space, and would like this functionality elsewhere in the firefox browser.

Thanks
John
