Why Firefox is not working in my computer?
Then select "direct connection to the internet". Hit okay, and you're laughing.
Firefox is not working on your computer either because it is not installed correctly or it is blocked by your security program or Windows firewall. In order to fix the issue, I suggest you download and install the latest version of the browser from the official web page. Also, press Ctrl + Shift + Delete key combination and clear all cookies, cache and temporary Internet files. If you still have issues, use the contact information from the official web page to get in touch with the support team.
