these are all great!

Here's a resource on more ways to approach safety and security online: https://ssd.eff.org/

This is also a useful resource: https://www.privacyguides.org/en/

and some tips that come to my mind (some of these overlap with the EFF guide):

• use privacy centered apps for chatting, instead of SMS use Signal for example
• use an offline password manager like keepass to generate very strong and unique passwords for every account
• use a privacy-conscious VPN like Mullvad to make it harder to track you down by IP and to safeguard your location
• enable disk encryption on your devices like laptops
• use NoScript to disable js from running by default
• use uBlock Origin to block malicious content (malware, scams, etc.)
• use a privacy conscious browser like LibreWolf and change your browser settings to not save history, to delete cookies upon closing, etc. - don't use other browsers like Chrome which have surveillance baked in
• use privacy conscious search engines instead of Google
• don't have corporate social media accounts, delete your Facebook, Insta, Pinterest, TikTok, X / Twitter, Bluesky, etc.
• use Facebook Container to prevent Facebook from profiling and spying on you (even when you don't go to Facebook and have no account, they still profile and track you as a non-user through other websites that put Facebook widgets on them)
• use Canvas Blocker to make it harder for websites to profile you through your unique canvas data
• use EFF's Cover Your Tracks tool to test how safe you are and what you need to do better
• use a tool to wipe EXIF data from your images before you post them - even just taking a screenshot of the picture on your computer and sharing that can be better than uploading the original
• use Linux and configure it to respect privacy instead of using corporate operating systems like Windows or macOS that have baked-in surveillance
• on Android use F-Droid as an alternative to the Google Play Store to find and install secure and open-source app alternatives to corporate apps that spy on you

Remember that in this day and age, the enemy includes the government, ISPs, and tech companies like Google, Apple, Facebook, etc.
