Firefox will not load paged properly once WINSelect is enabled when the "Prevent opening of files or folders from the address bar" is selected and enabled.
Firefox maintains a number of files on the disk that retain user preferences and browsing history. When the option to prevent the opening of files or folders from the address bar is enabled the ability to access these files is broken.
This issue was resolved in WINSelect version 7.5 build 706. Customers having issues with Firefox should update to the latest release of WINSelect to resolve this issue.
