How to Add a Chrome Extension?

Many apps can be integrated with your Gmail account via Chrome. Some come only as Chrome extensions, and all of them can be found on the Chrome Web Store:

  1. Go to the Chrome Web Store, use the search bar to find the desired add-on and click on it.
  2. Select “Add to Chrome.”
  3. Grant relevant permissions if you’re certain the app is from a trusted supplier, and you understand what data it will collect.

Note that allowing a third-party provider into your mailbox can pose a security risk. Before installing, check descriptions, user reviews, and ratings.

If you want to be extra careful, download only verified extensions. It’s encouraging to know that Chrome has its own protections in place. Often, it will disable extensions that seem unsafe or don’t come from the official Chrome Web Store.

Gmail Extensions to Improve Security

You can encode your data, prevent email tracking attempts, and un-send attachments with the following apps.

1. FlowCrypt

FlowCrypt allows you to encode your data when you send and receive sensitive or confidential messages and files via Gmail. Encrypting your outgoing emails ensures your communication doesn’t get intercepted or altered by hackers.

  • The extension uses OpenPGP encryption.
  • You don’t need any prior knowledge of security protocols, so it’s easy to set up.
  • It contains a digital signature feature so the recipient understands that the incoming mail is from a trusted sender.
  • Best of all, it’s free to use.
2. PixelBlock

PixelBlock prevents tracking attempts in your inbox. Install it, and senders won’t know whether you opened and read a message – no marketing research has been done on you. And just a hint, your employer won’t know you ignored their email 15 minutes before the end of the workday either.

  • If PixelBlock identifies and blocks a tracking attempt, you will see a red eye inside the email.
  • It doesn’t require any advanced permissions and doesn’t access, store, or send any of your data to remote servers.
  • It’s free to use and can be set up within seconds.
3. Digify

Digify is the go-to extension for sending sensitive attachments via Gmail. If you often send important files via email, Digify should be high up in your toolbox – especially if sending an incorrect attachment by mistake is something you should avoid at all costs. This extension may be a lifesaver in that case.

  • It provides file encryption and advanced safety features.
  • It offers a file self-destruct timer so recipients can access it only for a restricted amount of time.
  • You can trace who viewed your files, prevent downloads and printing, or revoke access after sending.
  • It also allows you to add a dynamic watermark.
