Downloader by AFTVnews (Amazon Appstore Fire TV and Tablet version)

From version 1.5.0-ForAmazonFireDevices:

What's new in version 1.5.0-ForAmazonFireDevices

• Added support for Android 13 and 14 devices.
• Added support for Phones and Tablets with a new touch-friendly interface.
• Added browser option to increase or decrease website text size on streaming devices.
• Changed download folder location from "/sdcard/Downloader" to "/sdcard/Download/Downloader" on Fire TV devices. This improves compatibility with future OS updates and matches the folder used on Google/Android TV devices. If files exist in the old folder, users will be asked if they want to move them to the new folder.
• Changed it so users of Fire OS 8 and Android 11+ devices no longer need to grant file access permission. This is an added benefit of changing the download folder location.
• Improved compatibility with Dropbox downloads.
• Fixed an issue where file access permission could not be set on newer devices.
• Fixed an issue causing files to be downloaded with the incorrect file extension.

Enter URLs, browse websites, or enter short codes to easily download files, such as app APKs, from the internet onto your Android TV, Google TV, phone, or tablet. Favorites allow you to easily save and open frequently visited URLs. Once files are downloaded, you can use the app's basic file manager to open them, install them if they are APK applications, or delete them.
