I need to use a website which requires me to have a browser with 128-bit encryption. I don't know what my firefox browser's level is. the "about firefox" box on my desktop says my current is Yahoo!edition yahoo-1.20. It also tells me it can't be updated. Thank you. PS: I've tried to use safari to go to this US government agency website, but safari won't "safely" open that page. I can get to that .gov website with firefox, but need to know answer to level of encryption.

Chosen solution

Firefox has supported 256-bit encryption for a very long time if the site provides support so the old Firefox 48.0.2 have certainly supports 128-bit.
