I hesitated before installing JComments because of a prior review that said it didn't work with IE8. But I decided to give JComments a try, anyway, and am very glad that I did. It works just fine with IE8 and Firefox on my site. I assume the problem might be with a specific Joomla template or type of template, but I tried it with a couple different templates without a problem. The component was easy to install and set up, with all the options I needed. It looks as good or better than any other system I have tried.
