Does firefox provide online protection from virus, malware protection , etc. automatically or otherwise?
I am a regular user of Mozilla firefox which scans all the online email downloads that I do.
But, I wish to know if I have to additionally install another antivirus / antimalware (protection) software for my online safety and computer safety as well?
Hello parthasarathi, you must install a security software because firefox(and all others browsers) does not have one.
see a great and useful add-on also : NoScript add-on
Firefox does give some phishing and attack site warnings
Firefox does work with software that you may have installed and for instance may enable scanning of downloaded files. If it is scanning now that indicates you have something installed. I believe Windows 7 makes Microsoft Essentials available for free. Windows 8 has Windows Defender or something provided by default.
The no script add-on is an extremely popular add-on that blocks a lot of nuisances and potential dangerous things. Firefox may soon include a click to play plugins feature that should be helpful.
BTW are you using Thunderbird ?
