You can check if you can start Firefox in Safe Mode by holding down the Shift/Options key.

See if you can use the Profile Manager to start Firefox in Offline mode.

Try to start Firefox with the about:blank page by creating a copy of the current Firefox desktop shortcut and add a space and -url "about:blank" to the target/command field.

If that allows to start Firefox then check the connection settings.

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":
