Using WINE and Security

I use UBUNTU LiveCD for Internet Banking. I don't need to install the programme.

I would like to be able to update Firefox, but can't on the LiveCD.

I was thinking of installing WINE, then using Windows FF might be possible.

I am a little concerned about conducting Internet banking with WINE installed because of possible security breaches (viruses/malware) etc.

Can you offer any advice

Am I worrying needlessly?

Thanks.

General info about the risks of using Wine here.

Aside from that - I wonder why you're using a Live CD for banking at all. If you're running Linux the only thing I would add is Noscript to Firefox and - if you're paranoid - AppArmor or SELinux. If you're using Windows the most important principle to make it safe is: Do not run it as admin. Use a limited account (or at least UAC) + SRP/Applocker. There are many extensive threads here on Wilders that cover these topics.

 

Why not?

sudo apt-get update && sudo apt-get install firefox

But if you only browse to one bankwebsite and then reboot you don't have to worry about having a bit outdated version of Firefox. The only vector left would be XSS and rogue apps, NoScript takes care of that.
