After the update to Firefox 63, Windows users with Quick Heal security software might be impacted by tabs repeatedly crashing while using 32-bit versions of Firefox.
We are in contact with the vendor about this problem. While they are looking into deploying a fix for this, a workaround for affected users is to disable the Browser Sandbox feature within Quick Heal:
- Open your Quick Heal security product
- On the Dashboard, click on
- Disable the Browser Sandbox setting by clicking the toggle next to it, so that it’s OFF:
- Restart Firefox for the change to take effect
As an alternative, affected users can also switch to 64-bit versions of Firefox in case their Windows system is supporting that.
