How to Fix Firefox Not Responding Error? Firefox is still one of the best browsers, available both on computers and mobile devices. Unfortunately, this application can introduce some bugs and problems that can sometimes be quite frustrating.
How to Fix Firefox Not Responding Error
If you are using Firefox on your computer, you have probably noticed that the browser has stopped responding to clicks and keystrokes. The label “Not Responding” will also be displayed in the title bar and the mouse cursor will rotate when it is on top of the Firefox window.
If you’re fed up with this problem, you’ve come to the right place; today we’re going to talk about how you can stop it, or at least reduce it.
Turn off Hardware Acceleration
Many don’t know, but your graphics card or graphics driver installation can cause Firefox to become unresponsive. It happens when Firefox is trying to use hardware acceleration. That’s why we recommend turning off hardware acceleration and see if that fixes the problem.
- Click on the menu button in the top right corner of Firefox;
- Select the “General” panel;
- Look for Performance and under that make sure that “Use recommended performance settings” is unchecked;
- Once you have done this, the option “Use hardware acceleration if available” will be displayed and you will need to uncheck this option as well;
- Restart Firefox.
If this fixes the issue, it was the hardware acceleration that caused the browser to stop responding. You can also try upgrading the graphics drivers to see if this fixes the issue, or just run Firefox without the hardware acceleration option.
Restore Duplicate Session Delete Files
Multiple copies of the Session Restore file can cause Firefox to become unresponsive. Follow the steps below to resolve this issue:
- Click on the menu button in the top right corner of Firefox;
- “?” Click the button and select Troubleshooting Information;
- A new tab opens where you need to click on the “Open Folder” button located under the “Application Basic” section;
- A folder with your profile files opens;
- Close your Firefox browser;
- Locate and delete sessionstore.js and duplicates such as: sessionstore-1.js, sessionstore-2.js.
You can then launch Firefox and see if this solves your problem.
Changing the “PAC” Application
If you are using a proxy autoconfiguration file (also known as a PAC), there is a good chance that Firefox will stop responding when loading websites for the first time (or when accessing websites you have not visited recently). To check if you are using a proxy autoconfiguration file, perform the following steps:
- Click on the menu button in the top right corner of Firefox;
- Click the “Options” button;
- Select Advanced Panel -> Network;
- Click Settings (this will open the “Connection Settings” dialog box);
- When “Automatic proxy configuration URL” is selected, you are using an automatic proxy configuration file.
We recommend that you disable this setting, which will prevent you from accessing the Internet. Instead, we recommend that you talk to your network administrator about your problem and have him or her look at this Mozilla Firefox webpage . We recognize that this does not completely resolve the issue, but users have reported that it is better than it was before.
Conclusion
We admit that Firefox still has many problems, but we can assure you that the developers are constantly working on them. There are reports that say that the new Mozilla Firefox 64-bit version fixes many of the problems that users with powerful computers had before.
