Firefox 26.0 freezing computer after changing settings

You encountered that problem because of the modifications you did in the internal configurations of the browser. When the browser starts or each time the browser launches, it will keep applying those settings that’s why it always end up freezing. That problem is caused by the settings you applied. Note: when tweaking the internal configurations of the browser, in this case Mozilla Firefox, modify one setting at a time.

After applying or modifying one setting, restart the browser then see if it works. Don’t modify multiple settings at a time because it can trigger compatibility issues in the browser making it unstable to run. To troubleshoot, first thing to try is to run the browser in Safe Mode. To do this, press and hold the Shift key when launching Firefox.

This starts Mozilla Firefox in Safe Mode. In “Firefox Safe Mode” window, you should have two buttons:

• Start in Safe Mode – this button disables all your browser extensions or add-ons and themes and disables hardware acceleration. When you leave Safe Mode and start Firefox normally again, all extensions, themes, and settings will return back to the state before you entered Safe Mode.
• Refresh Firefox – this button resets Firefox back to factory default but saving your important information.

If the problem continues, uninstall Firefox and install the latest. Download the free version of Revo Uninstaller and install it. Once installed, start Revo then select Mozilla Firefox among the applications and click “Uninstall”. Follow the normal uninstall process. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer.

When it is finished, exit Revo then download the latest Mozilla Firefox and install it. The download button basically downloads the web installer. If you want the offline installer, click the “Advanced install options & other platforms” link.
