Downloading is not working on Firefox.

[UnCrevard]

The fetch method to download file is not working for Firefox (cors problem most of the time).

A better way is to use the tampermonkey downloader. Simply add @grant GM_download to script headers then change the function downloadResource by GM_download(url,filename+".mp4")

GM_download is done with webext. So no cross-origin problem.

I have to fix the script at every update 😅

Thanks!

Add an if statment to sort between jpg and mp4..

if (url.contains("mp4")) {
GM_download(url, filename+".mp4");
} else {
GM_download(url, filename+".jpg");
}

I managed to get it working in Firefox by commenting out the 732nd line in code.
Before: 'User-Agent': window.navigator.userAgent
After: // 'User-Agent': window.navigator.userAgent

[grant]

Don't add me.

Confirmed. With CORS mode, at least Firefox seems to be like this. "User-agent header is only permitted for CORS when the server has opted in with "Access-Control-Allow-Headers: user-agent""

Haven't checked Chrome, but I would assume it's similar.
