Firefow downloads a file twice
Whenever I download a file Firefox downloads two of the same file. One is an empty file and the second file is the right size.
Example: I want to download a file called blender-4.0.1-macos-x64.dmg, when I start the download the first copy shows up immediately in my download folder called blender-4.0.1-macos-x64.dmg with zero bytes but another one is still downloading. Once that one is fully downloaded too I have another one in my download floder called blender-4.0.1-macos-x64-1.dmg.
Not sure how to prevent that, it is very annoying
