Add credentials to the proxy configuration

[octavioj]

Before submitting a bug report

• I updated to the latest version of Multi-Account Container and tested if I can reproduce the issue
• I searched for existing reports to see if it hasn't already been reported

Step to reproduce

I tried looking for this answer in the issues, but could not find it. When one configures a proxy, I would like to be able to specify credentials for the proxy site in the configuration. As it stands, when the tab is first used a pop up shoes up for the credentials and then it works but when a new tab is open, it seems the credentials are not "sticky" and the browser does not ask for the credentials and the proxy rejects the request.

Actual behavior

Credentials for the proxy only work the first time instead of all requests. The credentials are only asked for the first connection.

Expected behavior

Credentials for the proxy server should either be sticky or it should be possible to configure the credentials in the URL of the proxy server.

@octavioj Unfortunately I'm not sure that I understand what you are talking about. Did you configured proxy in some of your containers in Advance proxy setting? How you did it? Or you mean something else? Could you provide more information and/or screenshots.

On the proxy configuration field, one cannot add credentials to the proxy in the form of ://:@ . One can only configure :// . In the latter configuration, the first time a site is visited a password is asked by the browser but in a new tab or new window after some time, the password is no longer requested and the proxy request fails.
