First up, let me say that I seldom differ with
@osprey , I know better - he is so skilled in many more ways than i am
That being said, I have some advantages in running 75 distros, and on #4
...I'll just add that
FF-ESR was catapulted from v 128 to 140 middle of August, last, as described here
https://www.firefox.com/en-US/firefox/140.2.0/releasenotes/
,,,but that was only if you are on their release channel.
Trixie shipped with FF-ESR 128.13, and that in turn, can now be upgraded to 128.14.
It;s taken me a bit longer to prepare this material than I anticipated, so I will be providing it for consideration on my tomorrow, but I should also add that the article from Mozilla
produces some errors for me, and also has deficiencies, I will outline them on my tomorrow.
Cheers
Wiz
