What’s new:
- Mozilla is shipping a new Firefox version with RLBox Sandboxing to mobile and desktop platforms. This uses WebAssembly to isolate potential-buggy code.

When a video is playing, right-click on PiP button and select “Move Picture in Picture Toggle to Left Side” in the context menu.

- In addition to the RLBox security feature, to protect users against side-channel attacks such as Spectre, Mozilla has enabled fission or more popularly known as Site isolation for all users.
