Firefox provides a competitive array of features, customization options, and unique add-ons. Occasionally, it may encounter a problem. If Firefox becomes unresponsive on your Windows 10 or Windows 11 computer, troubleshooting is necessary.

If Firefox freezes or loads web pages slowly, it is a significant concern that should not be overlooked. We have compiled a list of solutions to help resolve this issue. Let’s get started.

1. Check Internet Connection

Patchy internet connectivity at home or office could cause Firefox to freeze or not respond. Check your Internet Connection by pressing Windows key + I to open Settings on Windows and go to the Network & Internet tab. You’ll see the connection status at the top.

To verify your internet connection, try opening another browser like Microsoft Edge or Google Chrome and load a few pages. If the internet is working, you can continue with this troubleshooting guide.

2. Restart Firefox

Firefox might not start if its previous session was abruptly closed. However, you can resolve this issue by simply restarting the browser.

Step 1: Launch the Task Manager by pressing Ctrl + Shift + Esc. Expand it by clicking on More details.

Step 1: Open Firefox on your PC. Click the menu icon in the top right, go to Help, and click About Firefox.

Step 2: In the following window, click the Refresh Firefox button to reset it.
