 ## Assumptions
 If you use any of the features below, please view the [common overrides](https://github.com/yokoffing/Betterfox/issues/87) sticky to restore functionality.
-* **Google Safe Browsing** (GSB) is disabled. We recommend use DNS-level protection like [NextDNS](https://nextdns.io/?from=xujj63g5), so check out our configuration guide [here](https://github.com/yokoffing/NextDNS-Config). If you have no other form of protection, then please re-enable GSB.

-* The native **password manager** is also disabled. If you don't use something like [KeePass](https://addons.mozilla.org/en-US/firefox/addon/keepassxc-browser/), [Bitwarden](https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/), or [1Password](https://addons.mozilla.org/en-US/firefox/addon/1password-x-password-manager), then re-enable Firefox's password management.
+* Firefox **Accessibility Service** is disabled to improve resource utilization and security. This will impact external application autofill capability (the ability to use a keyboard shortcut to fill in forms including logins) and screen readers. If you use assistive software, override this.
+* The native **password manager** is also disabled. If you don't use something like [KeePass](https://addons.mozilla.org/en-US/firefox/addon/keepassxc-browser/), [Bitwarden](https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/), or [1Password](https://addons.mozilla.org/en-US/firefox/addon/1password-x-password-manager), then enable Firefox's password management.
+* **Embedded tweets, instagram, reddit posts, and tiktoks** load on webpages, even though these requests are usually blocked when using Firefox's [Strict Enhanced Tracking Protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_strict-enhanced-tracking-protection).
