I have Firefox Version 00.0.1 (64-bit) on my iMAC. I wish to set up an outside account requiring 128-bit encryption. Is my browser sufficient to set up this account?

Inform me whether my Firefox Version 99.0.1 (64-bit) on my MacOS Catalina Version 10.15.7 is designed to handle 128-bit encryption.

The Firefox useragents up till the Firefox 4.0 Release used to have U to show it supported at least 128-bit encryption, even though it actually support 512-bit if the site provided support. The U was removed as it was obsolete for a long while.

My Firefox version is 99.0.1 (64-bit), not 00.0.1 as you may have seen on my earlier printing.
