New item dropdown list does not include "Web Page"
While it is possible to save a web page to Zotero from a browser, and it is possible to change the item type (using the selection list) to "Web Page", the new item drop down list (accessed via the "new item" icon drop down menu => More selection) does not include a Web Page choice.
