Firewall & Virus protection: Is Firefox blocked?

• In some cases, firewalls or antivirus programs block Firefox – for example, if a malicious tool has nested in the browser and would run when Firefox is launched.
• This is why, as a last resort, you should briefly switch off the firewall and deactivate the virus protection. We show how this works with AVG, for example, in another article.

Last resort. Reinstall Firefox

If none of this helps, you should reinstall Firefox: To do this, uninstall Firefox completely and then reinstall it
