Firefox version 84.0 for Android gives users the option to view their open tabs side by side in a grid view, according to the changelog. To switch from List to Grid view, open your tabs tray by clicking on the number next to the address bar, which shows how many open tabs you have. Next, click on the three-dot menu bar in the tabs tray. Select Tab settings, go to Tab view, and choose between List and Grid view.

For developers, the Firefox v84's network panel will be able to handle unexpected crashes and render debugging details such as a related stack-trace in the updated version of Firefox.

The release notes mention that the Accessibility Panel now includes an option for displaying elements in their tabbing order.
