At ITTSB.EU, we do not use, user tracking data, we do not care of which web browser you are using.
But other corporate level websites do, one of them this is
WD Digital website.
It appears that
Firefox ESR this is now started be targeted, as
Near to End of Support software.
Relative Nag messages these started to appear.

I do not worry of
Firefox ESR about this getting incompatible.
But I do worry about of whom is behind, as web developer company, of most corporate level websites?
They serving best interest of other corporations.
According to my personal view points, the website that cares of my browser software maker, this is an enemy.
