Years ago, Mozilla applied periodic releases of new Firefox versions just like Google did with Chrome unless a serious problem occurred. And recently, the company was forced to break the schedule, suddenly launching a new version of Firefox and asking users to update immediately.
According to Mozilla, Firefox has a zero-day vulnerability and cybercriminals are trying to exploit it for bad purposes. Therefore, users should download the latest version of Firefox, v67.0.3, for security. To view the version and update Firefox you can access the menu, select the "Help – Help" section and select "About Firefox – About Firefox". The browser will prompt you to update, but you can also manually update it by clicking here if the system updates automatically.
Mozilla often avoids providing details about security vulnerabilities. They just said that there have been attacks on new vulnerabilities that users have to update immediately to avoid getting worse.
The first to discover the flaw is Samuel Groß, who works for Google's Project Zero as well as Coinbase's security team. According to Groß, cyber criminals are trying to exploit this vulnerability to steal cryptocurrency.
Firefox rarely has to release an emergency update. The last time a zero-day hole patch was unexpectedly released by Firefox in 2016.
