To achieve a similar privacy and security level as Brave in Chromium-based browsers like Chrome, Edge, Vivaldi, and Firefox-based browsers like Firefox and Librewolf, you can consider the following tweaks:
1. Install privacy-focused extensions: Start by installing privacy-focused extensions like uBlock Origin or AdGuard to block ads and trackers. Additional extensions like HTTPS Everywhere and Privacy Badger can also enhance privacy protection.
2. Adjust browser settings: In Chromium-based browsers, you can access advanced settings by typing "chrome://flags" in the address bar. Look for options related to privacy, security, and tracking, such as enabling "Enhanced Tracking Protection" in Firefox or "Strict site isolation" in Chromium.
3. Manage cookies and tracking: Configure your browser to block third-party cookies and disable unnecessary permissions. You can also consider using separate profiles or containers to isolate different activities, such as work and personal browsing.
4. Stay updated: Keep your browser and extensions up to date to ensure you have the latest security patches and features.
Remember that while these tweaks can improve privacy and security, adopting additional measures like using a reputable VPN, practicing good browsing habits, and being cautious about the websites you visit will further enhance your online safety.
