Microsoft (MS) Edge has recently released versions 142.0.3595.65 and 142.0.3595.69. After upgrading to either of these versions, you may find that launching a web-based function from Oracle Forms applications or from non-Forms Java applets in EBS Release 12.2 or 12.1 no longer opens a new browser window or tab as expected.
These issues arise from an unexpected change in behavior introduced in Microsoft Edge versions 142.0.3595.65 and 142.0.3595.69.
Recommended Resolution

It is recommended if you are running either MS Edge Version142.0.3595.65 or 142.0.3595.69, upgrade to Microsoft Edge Version 142.0.3595.76 or later. For more information, refer to the following:
