When it comes to privacy-centric browsers, it’s no hidden secret that Mozilla Firefox stands right there at the top. The ability to block trackers, the presence of anti-malware and anti-phishing tools, fingerprint, and ad blocking are just some of its noteworthy features. Moreover, the browser also gets blessed with updates regularly.
While you aren’t going to witness the addition of new features with each update, however, there are always some bug fixes and patching of the underlying issues. As a result, it is more often than not recommended to be on the latest build. However, sometimes things might not go accordingly as planned.
There have been a few instances where users wish to rather downgrade to an earlier version. For example, a user recently updated his browser from version 44 to 49.0.1, but on doing so, issues began to pop up with the Selenium Firefox web driver. Likewise, some users complained that on updating Firefox, they ended up with its Quantum build, which they never opted for in the first place.
Well, these are just some of the many instances why one would prefer reverting to an earlier build. If you also echo these thoughts and wish to carry out the aforementioned task, then this guide shall help you out. Given here are the detailed instructions to downgrade and install an older version of Firefox.

Keeping all that in mind, here are the required downgrade instructions:

That’s it. You have successfully downgraded to an earlier build of Firefox. Now there’s just one thing left to do- disable its Auto-Updates feature.
Step 3: Disable Automatic Updates
By default, Firefox checks for the latest updates and if found will download and install it automatically. While it may come in handy in the general scenario, not so under the current circumstance where you have manually downgraded to an earlier build. So it is recommended to disable this feature now, which could be done as follows:

- Scroll to the Firefox Updates section, and select Check for Update but let you choose to install them.
This will disable the automatic updates on the Firefox browser. Though this will check for the newer version, but won’t install unless you manually confirm to update.
It’s not recommended to stay on the older version for a long, it can happen that successive versions might have the fix or patch release for the issue you are facing. Hence, keeping your Firefox browser up to date is highly recommended.
