Hi,
Thank you for coming Microsoft Q&A.
I noticed IBM Notes Browser Plug-in – Techniques for Efficient Usage says,
Suppose that your default PC browser is Internet Edge but, you do not want to use it. You want to use Lotus Notes browser plug-in in the Firefox. So, for this you need to perform following Notes.ini settings:
NOTES_PLUGIN_DEFAULT_BROWSER=Firefox
NOTES_PLUGIN_DEFAULT_BROWSER=IEdge
So you could try on your side with those configuration.
As Notes Browser is a third party product and out of our support scope, we know it is out of support now for IBM. We could use the thread for discussion with other customers who familiar with this issue. Or you could create another thread on IBM forum to check if they have any resource for it.
