How to Fix Firefox Slowness, Crashes, and Broken Extensions

Firefox problems often have quick fixes, so it's worth trying troubleshooting steps before reinstalling or switching browsers. Starting in Safe Mode, which temporarily disables extensions and default settings, helps reveal whether an add-on is the cause. If issues persist, users can check active extensions, hardware acceleration, and GPU rendering status, and consider reducing open tabs to lower memory use. For site-specific problems, the guide suggests reviewing content blockers, codec support, DNS settings, and cache. As a last resort, Refreshing Firefox or creating a new profile can reset the browser while preserving key data like bookmarks and passwords.
