I’d recommend Protonmail, as a substitute for gmail. It’s a Swiss based end-to-end encrypted email service that is expanding to Proton-calander and Proton-drive with their paid version. Their ProtonVPN also has a free version with limited locations. They also have apps for both android and apple.
To boost Firefox, I’d add-on-
Facebook Container- isolates your Facebook activity from the rest of your web activity in order to prevent Facebook from tracking you outside of the Facebook website via third party cookies.
HTTPS Everywhere- Many sites on the web offer some limited support for encryption over HTTPS, but make it difficult to use. For instance, they may default to unencrypted HTTP, or fill encrypted pages with links that go back to the unencrypted site.
Privacy Badger automatically learns to block invisible trackers. Instead of keeping lists of what to block, Privacy Badger automatically discovers trackers based on their behavior.
Privacy Possum monkey wrenches common commercial tracking methods by reducing and falsifying the data gathered by tracking companies.
uBlock Origin is not an “ad blocker”, it’s a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.
Firefox Multi-Account Containers lets you carve out a separate box for each of your online lives – no more opening a different browser just to check your work email! Here is a quick video showing you how it works.
Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. With the Firefox Multi-Account Containers extension, you can…
Sign in to two different accounts on the same site. For example, you could sign in to work email and home email in two different Container tabs.
Keep different kinds of browsing far away from each other (for example, you might use one Container tab for managing your Checking Account and a different Container tab for searching for new songs by your favorite band)
Avoid leaving social-network footprints all over the web (for example, you could use a Container tab for signing in to a social network, and use a different tab for visiting online news sites, keeping your social identity separate from tracking scripts on news sites)
Enhancer for YouTube™- Built to get the most out of YouTube, this extension comes packed with all sorts of features that allow you, among other things, to manage ads as you wish, control the playback speed and the volume level with the mouse wheel, automate repetitive tasks such as selecting the appropriate playback quality, configure dozens of keyboard shortcuts to control YouTube like a pro, and much more.
Decentraleyes- Protects you against tracking through “free”, centralized, content delivery.
Protects privacy by evading large delivery networks that claim to offer free services.
Complements regular blockers such as uBlock Origin (recommended), Adblock Plus, et al.
Works directly out of the box; absolutely no prior configuration required.
Bitwarden- A secure and free password manager for all of your devices. Bitwarden is the easiest and safest way to store all of your logins and passwords while conveniently keeping them synced between all of your devices.
Several of these also have companion versions in Firefox mobile.
If you are interested in other trustworthy add-ons, this icon shows that the add-on is an editorially curated extension that meet the highest standards of security, functionality, and user experience. Firefox staff, along with community participation, selects each extension and manually reviews them for security and policy compliance before they receive Recommended status.
Good luck! @ or message me if you need anything else.
Edit: I’d make a firefox account so you can log in and sync tabs/bookmarks across devices.
