    Mozilla has released important security updates for its Firefox web browser to fix two critical flaws. The company has warned that exploit code for these vulnerabilities has been published publicly, meaning hackers have the information they need to attack unprotected browsers. The two flaws affect the WebAssembly component and the DOM: Navigation component. If you or anyone in your family uses Firefox as your web browser, you need to update immediately. These security flaws could potentially allow hackers to run harmful code on your computer when you visit a website. While Mozilla has not confirmed active attacks yet, the fact that exploit code is publicly available makes this especially urgent. This affects Firefox on all devices where you have it installed, including computers, phones, and tablets.

    Here is what you need to do right now. First, open Firefox and click on the menu button (three horizontal lines) in the top right corner. Second, click on "Help" and then "About Firefox." Third, Firefox will automatically check for updates and install them. You may need to restart your browser to complete the update. Fourth, repeat this process on every device where you use Firefox. Beyond Firefox, the article mentions that Chrome, Adobe, and VMware also released security updates.

    Weekly cybersecurity briefings for families. No spam, just the threats that matter and what to do about them.

    If you use Google Chrome, click the three dots in the top right, go to "Help," then "About Google Chrome" to update. For Adobe products like Adobe Reader, open the program and check for updates in the Help menu.

    If you are not sure whether you use VMware products, you probably do not, as these are typically business tools. Make browser updates a weekly habit. Set a reminder on your phone to check for updates every Sunday evening. Modern browsers usually update automatically, but checking manually ensures you are never running outdated software. Teach your kids that keeping their browsers updated is just as important as any other online safety rule.
