For these we use Internet Explorer.
Here's one area that Firefox and Mozilla will NEVER function. Any site with ACTIVEX components.
Again, NEVER!
Hope this clarifies this issue.

I just want to report what for me is a shortcoming of Firefox (with which I am overall very pleased). Fidelity Investments has a way to get a chart showing the price fluctuations of individual stocks. I have no trouble getting the charts when I use IE. But when I use Firefox, and try to open a chart, I get a blank area where the chart should be an icon to click on to search for a plugin. When I click on it, I get a message that no plugin can be located. It is strange to me that Firefox does not allow for the use of such a chart. grandpaw
