How to Easily Downgrade Firefox to a Previous Version

It is certainly possible to downgrade Firefox to a previous version safely. Well, there can be many reasons why you want to do so. You might be facing some issues with the new build or you simply don’t like the new UI changes.

The guide to restoring the previous version of the browser is simple. Just download the older build, install it, and enjoy your browsing. But, you will also need to disable the automatic updates so that you could avoid upgrading to the newest build in the future. However, it’s not officially recommended.

Mozilla Firefox is one of the privacy-centric browsers which offers enhanced tracking protection, private browsing, anti-phishing protection, and more. But you wish to stay on the older build because Firefox is not loading pages after the update and is throwing issues like screen tearing, Tabs crashing, or simply cosmetic changes like border-radius not working issue.

Alternatively, you can also switch to a completely new browser like Opera if you think Firefox is throwing troubles or even downgrading isn’t helpful. It’s faster, reliable, and includes so many built-in features like VPN and adblocker.

Can we downgrade the Firefox version?

Yes, you can degrade the current version of the Firefox browser to an older one. There can be several reasons why one would want to roll back.

• New UI changes aren’t really welcome.
• Compatibility issues.
• The older version works better with add-ons.
• The new build is throwing troubles like any specific website isn’t opening.
• Unwanted new features.

It’s worth mentioning that you can revert to an older version of Firefox but it’s not recommended. Mozilla clearly states on its support page that downgrading to an older version can invite unknown vulnerabilities.

The developers do not support the older versions so you will be left with an insecure version.

   A new window will open that will tell you the system architecture.
