'''1. Use Private Browsing Mode''' Firefox has a Private Browsing mode that does not save your browsing history, cookies, or site data. Here’s how to use it: Open Private Browsing: Click on the menu button (three horizontal lines) in the top right corner. Select New Private Window. You can also use the keyboard shortcut Ctrl + Shift + P (Windows) or Command + Shift + P (Mac). When you use a Private Window, your browsing session will not be saved, and once you close the window, all history and data from that session will be erased. '''2. Create Separate User Profiles''' Firefox allows you to create separate user profiles, which can help keep your browsing data separate from others. Here’s how to create a new profile: Open Firefox and type about:profiles in the address bar, then press Enter. Click on Create a New Profile and follow the prompts to set it up. You can switch between profiles by going back to the about:profiles page. Each profile will have its own bookmarks, history, and settings, so others can use their own profile without seeing your data. '''3. Use a Different Browser''' If you want to keep your browsing completely separate, consider using a different browser for your personal use. For example, if you use Firefox for personal browsing, you could use Chrome or Edge for shared browsing. '''4. Clear History Automatically''' If you prefer to use the same profile but want to ensure that your history is cleared after each session, you can set Firefox to clear history automatically: Click on the menu button and select Settings (or Options). Go to the Privacy & Security panel. Under the History section, set Firefox will to Use custom settings for history. Check the box for Clear history when Firefox closes. Click on the Settings button next to it to choose what data you want to clear (e.g., Browsing & Download History, Cookies, Cache). '''5. Log Out of Email Accounts''' If you are concerned about others accessing your email, make sure to log out of your email account when you are done using it. This will prevent others from accessing your emails when they use the browser.
