I have used Firefox for a long time in my personal and professional use, but a few days ago when I try to open it, that time firefox seems some technical error and forcefully shut down. I did not know what to do so I decide to go Mozilla customer service for help, here they told me the solution which I want to need, but I need some thoughts who actually face this problem, hope I will get my answer.
A problematic extension can cause the problem, which can be resolved by disabling or uninstalling the extension.
The Refresh Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process...
Try uninstalling the extension, Clear Browsing History and try to open window... i think it should work
