— SeaMonkey 1.0.8 is old and has a limited extension ecosystem, so two practical, low-risk options that work well on older Linux installs are: (A) register a local helper program for .chm so SeaMonkey hands the file to an external viewer, or (B) decompile the CHM to plain HTML and open the result in SeaMonkey. ’s pointer to standalone viewers is valid; the extraction/convert approach is useful when a native viewer isn’t available or when staying inside SeaMonkey is preferred. (seamonkey-project.org)

To extract a CHM to a directory and then open it with any browser, install the command-line tools that come with chmlib and run the extractor. Example (Debian/Ubuntu-style):

sudo apt-get install libchm-bin
extract_chmLib file.chm /tmp/file-html
# then open file:///tmp/file-html/index.html in SeaMonkey

If a single-file conversion or richer output is wanted, arCHMage can extract or convert CHM to HTML/PDF (it uses PyCHM / chmlib under the hood). See the arCHMage project and the extract_chmLib manpage for details. (github.com)

To have SeaMonkey call a helper automatically, add a helper application entry and point it at a small wrapper script that extracts the CHM and opens the resulting index. SeaMonkey 1.x exposes the helper prefs under Edit → Preferences → Navigator → Helper Applications; add MIME application/vnd.ms-htmlhelp (or extension .chm) and point to the script. Example wrapper:

#!/bin/sh
TMP=$(mktemp -d /tmp/chm.XXXX)
extract_chmLib "$1" "$TMP"
xdg-open "file://$TMP/index.html"

Make it executable and set that script as the handler for CHM in SeaMonkey. Use extraction when dealing with odd encodings or broken CHMs, and prefer updated viewers/browsers where security matters. (seamonkey-project.org)

I don't know about Seamonkey extensions, but there is a Firefox extension called ChmFox which can be used to view chm files (Not sure if that's compatible with Seamonkey though).

There are also several standalone programs which can be used to view chm files in Linux.
xchm is a chm viewer which should be in the repos of most, if not all distros. I tend to use this as my default chm viewer.
GnoCHM, ChmSee and KchmViewer are three other chm viewers which immediately spring to mind, but there are probably several others available too. Your best bet would be to use one of your distros package management tools to search for chm and it will list any viewers that are available.
