i run Firefox Version 115.14.0esr (64-bit) on my older MacBook with OS 10.12.6, which I must use only to run Quicken for Mac 16.2.4. My other MacBook runs OS 14.6 and I would like to update Firefox on that machine, but keep all of the existing Firefox info. Can I update Firefox on the new Macbook and still keep the ESR version on the older machine, without losing all my history?y?
