View open document text files with Firefox

As ODF (Open Document Format) advances as an open alternative for text documents, spreadsheets and presentations it makes more sense to be able to open these documents from Firefox directly.

ODT file rendered by ODFReaderODFReader is a Firefox extension developed by that renders the contents of ODF text files (.odt) as HTML. Specifically it renders the contents.xml file inside .odt file (which are zip archives) applying a template (XSLT) designed by J David Eisenberg.

It has some limitations however as it doesn’t render the full styling or even images. So think of it as a quick tool to get to know what is inside without having to open another application like

Another limitation is that files can’t be opened directly from a remote web server but must be saved to the computer and then opened using File/Open.

    For regular text files you should use a more powerful text editor such as NoteTab Light (just Google it). For ODF documents, try They are much better suited for handling monster documents like yours.
