Web security

(1) Is this site recognised in the IT industry as being well informed ? If so, is it sensible to use the Browser with least vulnerability ?

M$ IE6 Patched /Unpatched vulnerabilities.

Opera Patched /Unpatched vulnerabilities.
Tabbed browsing problem has been addressed in V.7.6 (pre-release)
http://secunia.com/product/761/#advisories

Firefox V.0.x Patched / Unpatched vulnerabilities.
Some, if not all, addressed in V. 1.0 current.

If this is reliable information then Opera looks like... the business !!

(2) How do I know that I am actually looking at my Web Banking site ?
If I have typed or copied (Ctrl c ; Ctrl v) the URL directly into my browser from a known source, say a .txt file on floppy disc, but not ever from an e-mail or other web info.
There are no other pages / windows etc open or other progs running.
I can view the 'site certificates' ? How can I tell one from another, valid, invalid ? or a scam ?
