I cannot get firefox to read a .chm file. Old Netscape does, explorer does, chrome does. How can I get Firefox to read a .chm file?
In Firefox 24.0 -> Tools -> Options -> Applications, I cannot choose a program (hh.exe) to read .chm files. When I choose to open a *.chm file I have only the option of saving it, not to open it. Other browsers like Explorer, chrome, even old netscape 7.2 allow me to open it and the program finds I presume the hh.exe file and away you go. I cannot find a way to get Firefox (my favorite browser) to read chm files.

As I recall, Netscape 7.2 was a hybrid version made long after AOL shut-down their Mozilla programming operations, and that version incorporated some Trident code used by IE - which might explain the CHM compatibility. Not sure why Chrome handles it, though.
Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation.
There used to be a CHM Reader Add-on for Firefox - https://addons.mozilla.org/en-US/firefox/addon/chm-reader/ - but it hasn't been updated since June, 2008 / Firefox 3.6.
Sorry, Mozilla doesn't support "proprietary" formats such as that.
