File extension removed during download

I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

Steps to replicate the issue please.

I have tried to upload a screen cap jpg that is self explanatory but the upload stalls. Here is a Dropbox link to the .jpg

The file extension. You will see from the original post and the Dropbox link to the screen capture that Firefox drops the file extension .DAT during download. The filename is GXUP0004.DAT but in the download dialog box it is missing the .DAT file extension.

Yeah, the upload issue has been going on for a long time... Link to the download please and let me fire up my 2012 mac.

I've just tested the same download link, and the file extension is attached, so I assume that the cause of the problem is local to your installation. Here's my screenshot: https://www.screencast.com/t/ftP9eBAXum

Your Firefox settings and info are kept in a folder separate from the Firefox program, called your profile folder. Try creating a test profile, to see if the problem still occurs. See Profile Manager - Create, remove or switch Firefox profiles.

Same issue with a new test profile on this machine, a 2021 M1 MacBook Pro.

On a 2013 Mac Pro w Intel processor, it works fine. No loss of file extension. FYI, different profile. My profile is not shared across machines.

Both machines running same versions of OS and Firefox, Monterey 12.4 and Firefox 102.0

The last successful download of the firmware with Firefox and this machine was in February 2022. Since then, both the OS and Firefox have been updated, but as I pointed out previously, the Intel machine doesn't drop the file suffix and it is running the same version of the OS as the M1 machine is. So kind of points to M1 compatibility?

Same issue here with different fileextension (.ica).

Worked fine until approx. 2weeks ago. I am running Firefox 102.0-1 on 5.18.9-arch1-1. Tested with a fresh profile (had to set the proxy for the file in question) - error persists.

I have what seems to be this issue as well on Windows 11.

It's seemingly randomly truncating file extensions on .7z and .exe files for me. The most reliable file to cause this for me is the Java runtime from https://www.java.com/en/download/. It happens pretty much every time I download the jre as demonstrated in the image.
