Issue Description: My support ticket holder is running FireFox 96.0.3 and has to process records from the state, these records are available through links similar to this (not publicly accessible):

https://powerschool.tulsaschools.org/admin/reportqueue/prreport.html?jobQueueCurrentId=<id>&repName=<filename>&repType=html

When the dialog box offers to open / save the file the open option lists the file as a text file (ignoring the type tag above) and offers to open the file in the system's default text editor.

Choosing the save option downloads the file and saves it as a .html file... loading the downloaded file has the expected result of displaying the Web page as intended.

Other browsers (Chrome, Edge) load both files as HTML as expected. Steps taken: Cache and Cookies have been cleared, FireFox has been refreshed, and I closed and re-opened FireFox.

How can I recover the ability to display this HTML file as a webpage through the open option and not as source (text)? Resources: File saved in the temp folder & opening as source: FireFoxReport-Open.png Expected result (and result in other browsers: FireFoxReportOpen-Expected.png - Being edited for privacy

This might be about of how the server sends this file to Firefox. You can check the HTTP response headers in the Network Monitor.


You can try to set browser.download.sanitize_non_media_extensions = false on the about:config page to see if that makes Firefox show the correct file extension when you save the file.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
