Issue with Downloaded PDF Filename in Android DuckDuckGo Browser

[jeeva-sil]

Describe the bug

I'm trying to download a PDF file with a specific name using HTML and JavaScript. The file is correctly named "myFile.pdf" in the code, but when I download it using the DuckDuckGo browser on an Android device, the file is saved with a random string as its name, such as "f7160bf-07aa-4c50-8765-f3651a345g675.pdf". How can I ensure the file is downloaded with the specified name?

How to Reproduce

Code:
Here's the code I'm using to convert a base64 string to a PDF file and download it:

`

<script>
    document.getElementById('downloadBtn').addEventListener('click', function() {
        const base64Data = 'your-base64-string-here'; // replace with your base64 string
        const byteCharacters = atob(base64Data);
        const byteNumbers = new Array(byteCharacters.length);
        for (let i = 0; i < byteCharacters.length; i++) {
            byteNumbers[i] = byteCharacters.charCodeAt(i);
        }
        const byteArray = new Uint8Array(byteNumbers);
        const blob = new Blob([byteArray], { type: 'application/pdf' });
        const link = document.createElement('a');
        link.href = window.URL.createObjectURL(blob);
        link.download = 'myFile.pdf';
        link.click();
    });
</script>

`

Steps to Reproduce:
Open the above code in a browser.
Click the "Download PDF" button.
Observe the downloaded file name.
Expected Behavior:
The file should download with the name "myFile.pdf".

Actual Behavior:
The file downloads with a random string as its name (e.g., "f7160bf-07aa-4c50-8765-f3651a345g675.pdf").

Additional Information:
This issue occurs specifically on the DuckDuckGo browser on Android.
The code works fine in other browsers (e.g., Chrome, Firefox).

Questions:
Why is the DuckDuckGo browser on Android renaming the file?
How can I ensure the file downloads with the correct name in the DuckDuckGo browser?
Any help or guidance would be greatly appreciated!

Expected behavior

The file should download with the name "myFile.pdf".

Thank you for submitting this report and providing detailed steps to reproduce the issue. We are aware of this problem; however, we are currently limited by the existing WebView API, which doesn’t surface the filename to us in the case of blob URLs, such as the one your code generates.
