I have installed this CHM reader on Firefox 3.5.10 running under Windows XP. The big problem appears to be that Firefox does not recreate the Toolbar and the Navigation Pane that are generic to the CHM format when read from Microsoft Internet Explorer. Consequently, the means of navigating a CHM document are lost! Therefore, this add-on is a regression, and I see no purpose in retaining it.
