Mozilla Firefox Browser Keeps Crashing and Freezing

Firefox browser from Mozilla Group is one of the most popular browsers today. It is a fast and technologically superior browser.

However, some users (including me) felt frequent crashes and freezing issues with the Firefox browser. Let us check why the Firefox browser causes freezing and crashing on a device and fix the problem.

The first part of this tutorial checks the reasons for a Firefox browser crash on a computer. The second part will teach you tips to avoid frequent Firefox browser freezing and crashing issues.

1. Outdated Browser:

   An outdated browser version is the number one cause of the freezing and crashing of the Firefox browser on a device.

2. Too Many Extensions:

   The second reason for the Firefox freezing problem is too many installed extensions.

3. Too Many Cookies and Site Data

   You might not have cleared the browser cookies and cache for a while. Firefox will show problems once it has a lot of saved site data and cookies.

   Malware applications like adware always pushes your browser to open new websites. It will create problems with the smooth working of the Firefox browser, and eventually, it will freeze or crash.
