There may be various reasons why your Firefox browser is crashing or freezing very often. But there are common factors responsible for the malfunctioning of the browser:

When you refresh Firefox, a new profile folder is created where your personal Firefox settings and information are stored. But extensions and themes stored in the previous profile folder will be deleted. Only your bookmarks, cookies, browsing history, passwords, and auto-fill information are retained.

If you do not experience Firefox instability very often, the quickest fix is to force close Firefox from the Task manager and restarting it.

Closing the Firefox using the red close icon at the topmost right of the window is impossible when the browser becomes unresponsive.
To close the Firefox browser via the Task Manager. Here are the steps:
Firefox automatically updates itself by default but you can also do it manually. If you update Firefox manually, you need to restart Firefox for the update to be installed.
Reinstallation of the Firefox browser might also help especially if the previous installation is corrupted. For Mac users, you can uninstall the Firefox application first and follow these steps on how to download and install Firefox on a Mac computer.
For Windows users, uninstall the Firefox application by:
Step 1. Searching “Add or Remove Programs” from the Windows menu. Step 2. Look for Firefox and uninstall it.
Then download and install the application again from Firefox’s website.
Updating the right components that may have caused the problems had always worked in this kind of situations. Out of date graphics, card and drivers may be one of these reasons. So make sure that your drivers have the latest versions.
A lot of Firefox users have also tried clearing the browser’s cache as a solution to its unresponsiveness. This is the most popular method of fixing the problem. By deleting cache and cookies, potential reasons that may have caused the problem are eliminated.
