Ce setari trebuie sa fac ca de exemplu atunci cand intru pe Facebook sa nu vada nimeni ca sunt on

Certainly! To appear offline on Facebook using a desktop web browser, first log into your Facebook account. Then, click on the Messenger icon located in the top right corner of the page. In the Messenger menu, find the options or settings gear icon, usually at the bottom or top of the list.
Click on it and select 'Turn Off Active Status.' A new window will appear, giving you a few options.
You can choose to appear offline for all contacts, for all contacts except some, or only for some contacts.
Select your preferred option and then click 'Okay' to save your settings. This will make you appear offline, and others won't be able to see that you are online.
Remember, these settings might not affect your online status on other devices, so you may need to adjust settings on mobile devices separately.
