So, what can i say Waardering 4 van 5 sterren

It is good idea to open .chm's in Firefox.

1) But i cannot see index/contents on sidebar at all (Firefox 3.0.5, plugin 0.2.3)

2) Have a file which plugin fails to open (if Author is interested - )

3) Fix a work please)

4) Maybe, it would be useful - .cmd code which can be associated with .chm files in explorer (works only for local files):
start "" "\firefox.exe" "chm:file://%~1"

firefox as CHM-MIME-handler Waardering 4 van 5 sterren

It would be great, if firefox could open chm-files as one of its common formats through that plug-in. It is a pitty that in order to open CHM, one cannot just double-click the file, but has to open through a menu or button.

Didn't work for me.

works really well..
only one suggestion though:
the option to have the side bar autohide, or to autohide whenever the user goes to another tab. ;)

good work!

error on linux-64 Waardering 4 van 5 sterren

Gentoo x64, unsupported platform. Went to sourceforge, got source
from svn. Was able to compile only after:
adding -L/usr/lib64/nspr for gcc.
After installing plug-in and trying to open chm got this error:

OpenDownload (101)
An unknown error occurred.
[Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsILocalFile.initWithPath]" nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)" location: "JS frame :: chrome://opendownload/content/opendownload.js :: openDownload :: line 30" data: no]

Problem With Windows Server 2003 + firefox 3.0.3 Waardering 2 van 5 sterren

I see it does not work on my PC with newly installed OS (windows server 2003 R2) + firefox V3.0.3.

I tried with some CHM files with various size and types but the result is an empty page.

If I try with MSDN magazine (Oct 2008) I see that firefox run at 100% CPU and its progress bar is blinking.

please review and fix. I hope that I can use this addon.

many thanks,

它真的能支持firefox3吗? Waardering 4 van 5 sterren

装的是chm reader
可是后来我换成了firefox 3.0.3
升级chm reader 到0.2.3后,
点open chm files无任何反应……
我用的是redflag 6.0

A few things.. Waardering 4 van 5 sterren

This does work, I'm impressed. I will list a few things that are needed..

Support for opening CHM files from a web page. Support for viewing CHM files from the Archview extension.
Push buttons should (+) (-) display only if the section has 1 or more articles.
Index: Find as you type.
Search content (not to sure how easy this will be to implement)

h-link not supported Waardering 4 van 5 sterren

This add-on is really good. But there are some weakness. On windows, Firefox 3, the hyperlink to another page seems not being supported-- the hyperlink is displayed as underlined text, the it does not jump when I click the mouse button on the text. The 2nd problem that is not convenient is that I've got to adjust font size again when I open a new chapter even in the same chm file.

Hi cee2G Waardering 5 van 5 sterren

The same problem is solved after I compile the add-ons myself, you can find information on

Nice Add-on~~~ Waardering 4 van 5 sterren

It's great to view chm files in my favorite browser.
It could be great if these two problems are solved:
1. I have to set the font-size whenever I go to a new page.
2. It can not open a certain page whose link has some non-latin characters.

Good idea but ... Waardering 3 van 5 sterren

Good idea, but doesn't seem to work properly. The most annoying thing - font size need to be adjusted every time when go to next page.

Waardering 4 van 5 sterren

Excellent add-on. But when I zoom the font size on a page, it doesn't remember that. I've to zoom on every single page, using FF 3.
