Firefox for Android
Release Notes

For new users, the address bar's default position has moved from the bottom of the screen to the top. The Customize > Toolbar setting can be used to move the toolbar back to the bottom.

Firefox now uses resizes-visual as the default value of the interactive-widget property of the viewport <meta> element. This means that when the software keyboard is shown, Firefox resizes the page's visual viewport but not its layout viewport, avoiding an expensive reflow and resulting in a more usable layout on many pages.

Various security fixes.
