I used the download/install method suggested by Boondog successfully this time for 17.0. I will have to wait for 17.1 to give it a try. Did it have something to do with the first kill date function before this extended extension? Just curious. Thanks...
I had them ready (regular backups of all files). Did not need them. It was as if the auto update had worked. Smooth as silk & still working fine today. Good hunting all. :>))
SUCCESS... I used Firefox Setup 115.17.0esr.msi as suggested by Boondog. Simply ran it & let it do its thing. I am now updated to 17.0 & all seems fine. Thanks Boondog.
Good news. I will report back when I use the msi file on my W7-HomePremium/SP1 64bit Acer Aspire 5733Z fully updated (security) as of Oct 2024. I keep my profiles/favs/PWs saved x2. Hoping your experience is my experience. ;>)
