Issue/Introduction

Gen 8.6 ASP.NET application .ashx pages do not load in Firefox and return error "The resource cannot be found".
Firefox version is up to date at version 115.02

The .ashx file redirects to the browser specfic page IefFirefoxApplication.aspx
 



Under Chrome the redirection to browser specific page IefChromeApplication.aspx is successful:

Environment

Release : 8.63

Cause

In the application install directory there are these 4 versions of the .aspx file for the supported browsers but there is no IefFirefoxApplication.aspx:
IefChromeApplication.aspx
IefEdgeApplication.aspx
IefIEApplication.aspx
IefMozillaApplication.aspx

Resolution

In the application install directory copy the file IefChromeApplication.aspx to IefFirefoxApplication.aspx and the problem will be resolved.

Optionally, in the new file IefFirefoxApplication.aspx, the html title can also be changed i.e.
FROM:    <title>"IEF Chrome Application"</title>
TO:    <title>"IEF Firefox Application"</title>


** NOTE: As of August 1, 2023, Gen Engineering advised that the above workaround is valid and they are researching further with a view to issuing a PTF to resolve the problem.
