- facebok gives user the option of dragging a button to the toolbar, that will post any website to your facebook profile when clicked. ...
- facebook uses the bottom line of the browser to set up site-wide links. this bar does not render correctly in k-meleon.
K-Meleon's surfaces... are not from XUL. XUL extensions for Firefox will not work.
You will need to construct Your own buttons or menu items.
"wrong page on facebook.com": my guess the page is part of a frameset.
Bookmarking the whole frameset will often give You the some pre-programed entry page (only well constructed sites with framset pages compensate this).
If You right-click on frameset pages (right into the section/page that is interesting, framesets consist of several html pages) You get a menue item called FRAME. You can bookmark and/or open as standalone page. I normally try the later to make sure that I bookmark the right page
K-Meleon's menus are context sensitive - the browser shows You different usable items in right click menu in different context..
seems like everyone uses facebook these days
You are right: facebook and many other sites are not optimized for K-Meleon but for Firefox and IE.
