After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open. This problem only occurs when using Firefox. If using Microsoft's browser there is no problem. Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years. I prefer the Firefox browser versus Microsoft. Please research and repair this issue.
