When I open an html file from the desktop all I see is source code rather than webpage.

I have tried clearing the cache and reading other questions similar. I have a mac and am opening these files from the desktop, not a server or anything so It's incredibly annoying that firefox wont open them as html files even though that is what they are saved as. Also there is no .txt after them. They are purely .html files.

Try to delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.


Firefox 16.0.2 is the last version that works on an Intel Mac with the OS X 10.5 operating system.

Another option to consider is to install the last Firefox 10.0.x ESR version as that version is more recent than the Firefox 16.0.2 version.
