Uploading multiple files with firefox (mobile)

[jatentaki]

When I upload phone -> PC with firefox mobile and select multiple files at once, I instantly get a successful upload message but only some of the chosen files appear on my PC and are corrupt (0 bytes). It works fine with a single file as well as with chrome mobile.

Thanks a lot for the tool, it solves a big pain point for me :)

Hi. How big are the files you're trying to upload? and how many? and does it work with another browser?

Hi, I tried uploading anywhere between 1 and ~150 .jpg images about 2mb each. It works for a single one but not for more. It does work with chrome (as I stated above).

Thanks for your interest

Ok I managed to reproduce the problem. Firefox mobile does not properly send the multipart form like other browsers do.

When testing with two files...

Chrome mobile:

{
  'content-length': '522814',
  'content-type': 'multipart/form-data; boundary=----WebKitFormBoundaryBHWzyAyea9HBaafn',
  'accept-encoding': 'gzip, deflate',
}

Firefox mobile:

{
  'content-length': '230',
  'accept-encoding': 'gzip, deflate',
  'content-type': 'multipart/form-data; boundary=---------------------------116521216141164983863359111',
}

content-length is only 230.

I've googled a bit and tried to use fetch instead of axios but nothing seems to solve this issue on firefox mobile.

Maybe we need to upload files one-by-one

I just tested with firefox on mac, and it works. So it's definitely a firefox mobile issue
