Lovely use of Privacy Possum, does what 3 extensions can do in one! As with other configs unless you know WFW off by heart use a piece of software like Tinywall (or recommended other) to stop various threats below:
- Ransomware- Some ransomware must contact the C&C server before any encryption can take place. So, you get an outbound connection alert when ransomware runs. Block it and it won't be able to harm your data.
- Keyloggers- They can log almost anything. Problem occurs when the recorded data is transmitted to the cyber criminals who can misuse it. Damage can be prevented if you stop any malicious connection to happen from your end.
- Remote Access Trojan (RAT): Some RATs will operate by injecting directly into a legitimate Windows process like svchost, using this to connect out instead of some other executable that can be grossly apparent. Firewalls will not only block the hollowed process from connecting out, but they do it silently with any user input.
The name of the game to fame from
@Evjl's Rain extensions tests seems to sway towards Bitdefender Trafficlight, but this is completely you own judgement if you wish to stay with the Malwatebyte's security extension, even though I found it's CPU browser usage much high than others, plus there is a lot of false positives.
