Firefox for Android Community Forum

I understand that changing the file extension of downloads to match the file contents is a protection feature but it is causing me issues on mobile.

I am trying to download .rosz files, they are essential .zip files with a custom extension. These files are generated from one web app and are going to be uploaded into another web app and the receiving app will reject files with the wrong extension. The current behavior changes the file to .zip and requires me to manually locate the downloaded file and rename it back to .rosz .

Is there a setting that I can change to prevent download file extention renaming? I understand the security issues it can present and am willing to accept the risks.

I'm on the android version of firefox.

So i browse in private tab, find image and file i want to download. I download them, and few second after the tab is closed or i closing the app, the file delete itself. At best it stays for few minutes. Sometime it delete itself before i close the tab and open the gallery/file manager to check if they still there. Only resulted on me seeing they delete itself.
