I tried Iron itoffshore. The .deb-file. It is indeed almost a copy of Chrome/Chromium.
But the full list
of extensions is not present. This one in Iron is a slim alternative.
(Extensions are the reason I still use Firefox too for other things then what I use Chrome for.
They are good in add-ons (extensions).)
Only in the full Chrome extensions-list I can find what I need (and also thát list is rather
small for what I prefer
I'm rather spoiled, I think.
But it has to do with my work here.
When there would not be this need I could use Iron immediatly. Thanks again for the tip.
I'll keep it in mind and maybe I'll use it later for something very handy.
For now Chrome will do with the workaround and the home-phone I accept.
It is way better then Epiphany, Midori etc. and for now the best fast second browser in my situation.
