How can I open .chm files in Firefox?

I'm trying to open a .chm file in Firefox. I've read that this is possible -- ultimately, I want to save the content out as something more accessible. But whether I right-click the .chm file in Windows Explorer, and use "Open with ... Firefox", or use the File/open menu command from within Firefox itself, it merely brings up a dialog box in Firefox asking me where to save the file, with the same filename and filetype extension. I save the file, and the pattern repeats. It never opens.

I can open the file in the Microsoft Help File utility, so I know it's a valid file, but that utility doesn't let me save or export it in any other format.

I've gone into Options/Applications in Firefox to set how this filetype is handled, but can't find any reference to Compiled Windows Help Files on the list in any form, and I don't know how to add it as an option.

How can I resolve this, please?

For reference, I'm running Firefox 35.0.1 on Windows 7 x64. Thanks for any help.

No, not really. I mean, thanks, but I know what a CHM file is. I specifically asked about opening it in Firefox. I'm not sure why you thought I deserved a Bing-ified LMGTFY response, Fred.

Once you identify what you need for the file, you will know how to use it.

No, I know full well what .chm files are, and how to search for info about them. I'd rather have an answer to the specific question I asked, which I asked for specific reasons.

You seem to have ignored my question, and leapt to massive assumptions about what I "really" need, and it's puzzling that you persist with them even after I've told you your assumptions are wrong. Your answers come across as somewhat patronising, maybe intentionally so - is that what you intended? Why would you do that?
