What is a firewall and how does it affect Firefox?
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted network and an untrusted network, such as the internet, to prevent unauthorized access and malicious activities. When a firewall is enabled, it can block certain applications, including web browsers like Firefox, from accessing the internet if it detects suspicious activity or if the application is not configured to bypass the firewall.
In the context of Firefox, a firewall can block the browser’s ability to connect to the internet, preventing users from accessing their favorite websites, online services, and other web-based resources. This can be frustrating, especially if users rely on Firefox for work, education, or entertainment. To regain access, users need to configure their firewall settings to allow Firefox to bypass the firewall and connect to the internet. This can be done by creating a firewall rule that specifically allows Firefox to access the internet, or by disabling the firewall temporarily while using the browser.
