Web browsers on the Mac since Mosaic have stored bookmarks in an HTML file. Chimera apparently breaks this long tradition and uses it’s own simple XML format. Is this progress? No. Sure, they do fun things like type=“toolbar”, but the same extensibility could have been achieved with XHTML and some new elements or attributes under their own namespace. Now, we have a politically correct file format that cannot be viewed in a web browser or parsed by existing bookmarks-parsing code. Oh well.
