1638226 - chrome.downloads.download works in Chrome but fails in FF after recent update.

Status: RESOLVED DUPLICATE of bug 1637973

(WebExtensions :: Untriaged, defect)

Description

[Deepesh Agarwal]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

This code, in my web-extension background script works fine in Google Chrome for same filenames but not in Firefox, this started happening after recent FF upgrade:

chrome.runtime.onMessage.addListener(function (message) {
var url = message.url;
var fname = message.filename;
fname = fname.replace(/[\/:"*?<>|\r\n]+/g, "_");

chrome.downloads.download({
	url: url,
	filename: fname,
	conflictAction: 'uniquify',
	saveAs: true
});

});

Actual results:

Unchecked lastError value: Error: filename must not contain illegal characters

Expected results:

File should download without said error in console. I debugged the issue and found any filename having consecutive spaces will fail, using .replace(/\s+/g,' '); fixes the issue.
