The About Mozilla Firefox window will open and Firefox will check for updates and download them automatically.Open Firefox and click the hamburger menu icon (three horizontal lines), then Help, then go to About Firefox.The fix is primarily on Mozilla’s back-end, but the company advised users to update their Firefox browser to the latest version, which is now Firefox 93. This means that other add-ons with the same technology will now default to direct connections when Firefox makes an important request. Other steps that Mozilla has taken to stop the spread, include the pausing of new approvals for extensions that use the proxy API until a proper fix is implemented. The add-ons have since been blocked on Firefox, preventing other users from installing them.

Mozilla didn’t divulge the specific extensions but did say that they had been downloaded a collective 455,000 times. But that is exactly what the compromised extensions did: blocking access to updates and web blocklists. We all know that software and operating system updates are crucial to keeping malicious programs out of your computer.
