Fixing an unresponsive Mozilla Firefox on Linux

How to fix “Firefox is already running but is not responding” error message

In this guide, we’ll show you a few different methods for fixing the Firefox is already running but is not responding error message on a Linux system.

First, let’s go over a few reasons for why this error may be occurring. It’s not uncommon to have an application freeze or “hang” every once in a while, so if this isn’t an issue that you repeatedly have with Firefox, you can probably simply kill the process and get back to what you were doing.

On the other hand, the problem has been known to become perpetual in situations where there’s an issue with the profile file. Firefox stores a user’s personalizations and settings inside a “profile” that is accessed every time Firefox opens. If you’re experiencing this error often, it can be helpful to create a brand new profile and import your old settings.
