Answer 1

you can set proxy details with credentials here in your automation code as above answers explained but another way to do it without sharing your details in your java or python code with firefox profile.
firefox provides profiles, we can create profile for every user and customize it for proxy ,bookmarks etc.
windows user : open run(win+R) and type 'firefox -p'
linux user : run command 'firefox -p'
1- it will open a dialog box where you can create your profile then select that profile and open firefox.
2- open a new tab and search 'about:config' .accept the Risk and Continue then click on show all
3-here you can search and set all the property
example:
network.proxy.type   1
1 for Manually
2 for Automatic proxy
for Manuall proxy -
property                     value
network.proxy.http              your proxy ip
network.proxy.http_port               port number
network.proxy.ssl               your proxy ip
network.proxy.ssl_port               port number
network.proxy.ftp               your proxy ip
network.proxy.ftp_port               port number

(to find your profile name )
Linux : cd .mozilla/firefox/
windows: Press. +R on the keyboard. A Run dialog will open. Type in: %APPDATA%\Mozilla\Firefox\Profiles\ Click OK. A window will open containing profile folders now load this profile in java code

FirefoxOptions options = new FirefoxOptions();
options.setUnhandledPromptBehaviour(UnexpectedAlertBehaviour.ACCEPT);
FirefoxProfile profile=new FirefoxProfile(new File("path of your profile"));
options.setProfile(profile);
WebDriver driver = new FirefoxDriver(options);
System.setProperty("webdriver.gecko.driver", "path of gecko driver");
driver.get("url");
