i need 128 bit encryption. how do I determine if FoxFire has 128 bit encryption?

On any page click on the little 'i' in a circle (at the left end of the address bar), click on the arrow (>) then click on 'More Information'.

Under the Security tab scroll down to 'Technical Details'.

(On this support forum page you will see '128 bit')

Firefox and not Foxfire.

Firefox has supported 128-bit encryption for a very long time and also supports 256-bit encryption if the site provides such.
