Windows: Refresh Firefox in the background

Starting with Firefox 90, Windows users can update Firefox in the background. If the option is activated, Firefox then checks if there is a new version every seven hours and, if necessary, installs it without disturbing the user. This is especially useful for users for whom updates are annoying when starting the program.

This feature will be gradually rolled out. If you want to activate it earlier, you can use a file Help from Mozilla consequences.

SmartBlock 2.0

The SmartBlock mechanism was introduced with Firefox 87, which is activated in private windows and in all windows for those users who have activated strict protection against activity tracking, combining privacy and compatibility with the web. Firefox replaces the scripts of known tracking services with some kind of alternative script, ensuring that website compatibility is not compromised while disabling actual functionality. For example, website functions that require Google Analytics can be called without actually being executed and without script errors, unlike without SmartBlock, because Google Analytics is blocked by Firefox.

Firefox 90 brings SmartBlock 2.0, an improved version of this mechanism. For example, Facebook scripts are still prohibited on websites, but are allowed for the corresponding website at the time the user decides to use the Facebook login applicable to many websites. So far, Facebook login cannot be used without turning off protection beforehand.

HTTPS Mode Only: Manage Exceptions in Settings

Firefox has an HTTPS only mode where Firefox only loads pages over HTTPS, not over an unencrypted HTTP connection (exceptions are possible). This can be activated either always, only in private windows or not at all. From Firefox 90, it is possible to manage exceptions to this mode directly in the Firefox settings.
