Firefox 70.0 download and update
Updates are made available on October 22, 2019. We publish the release overview early usually to provide users with information prior to the release.
Once released, you may run a manual check for updates in Firefox by selecting Menu > Help > About Firefox. Firefox opens a new window that runs a check for update and either suggests to download and install it, or does to automatically.
The following pages list direct downloads for supported Firefox channels.
Firefox 70.0 Changes
Enhanced Tracking Protection improvements
Mozilla improved the built-in tracking protection feature of the Firefox web browser once more in Firefox 70.0. The organization added the social media tracker blocking component to the standard setting making it a default in the new Firefox version.
Firefox users had to switch to strict or custom blocking in previous releases to enable the protection.
Social Media trackers are used by social media sites like Facebook or Twitter.
Tip: check the about:protections page of the Firefox web browser to look at protection statistics.
Firefox Lockwise improvements
Firefox Lockwise is a password management solution that Mozilla launched some time ago; it is part of the Firefox web browser and can be opened at any time by loading about:logins in the browser’s address bar.
The desktop version of Lockwise supports synchronization and the creating, updating, and deleting of logins and passwords.
The new version supports integrated breach alerts powered by Firefox Monitor in the new release; this informs users about potentially compromised passwords so that users may react by changing passwords quickly.
Firefox Account icon and menu, and What’s New icon
Mozilla placed a new Firefox Account icon on the Firefox toolbar. A click opens account specific options, e.g. to sign in to a Firefox account, enable synchronization, access logins and passwords, or open the Firefox services Monitor and Send.
Firefox users who don’t need the icon can remove it with a right-click on the icon and the selection of Remove from Toolbar from the context menu.
To add it back at a later time select Firefox Menu > Customize and drag & drop the Firefox Account icon to the toolbar again.
A What’s New icon is also available that highlights new releases and features.
- Firefox may suggest secure passwords when the user encounters input fields that have the autocomplete=”new-password” attribute.
