Mozilla Firefox Testing FAQ
When will Firefox hit version 100?
Firefox is on a rapid four to five-week release cycle and at the moment the latest version is Firefox 88. That means in about 48 to 60 weeks Firefox will reach version 100, which is approximately February 2022.
Who will reach version 100 first – Firefox or Chrome?
At the moment, Google Chrome is at version 90 and Mozilla Firefox is at version 88. That means Chrome is 2 versions ahead of Firefox. However, Google Chrome is on a little bit slower release cycle than Firefox, averaging a new version every six weeks. As Firefox has a quicker release cycle, it's expected to hit version 100 first in February 2022, while Chrome is expected to hit version 100 only in June or July of 2022.
When will the next Firefox version be released?
Currently, the latest version is Firefox 88. The next version will be Firefox 89 and it will be released on June 1, 2021. We'll be installing this version as soon as it's released and making a blog post about it as well.
