What is an " unsupported browser with unsupported add-ons " ? sorry, I am a IT retard

I use MS Security Essentials and are religious about
never opening an unknown email ( OK, my hotmail was hacked.... ) and have no bankink or important data stored. My laptop is useless with any other browser configuration for me. Is the only alternative to have a second computer for things like internet banking that uses FF V13 or similar and all the AV/anti malware systems ?
Thanks.
