Thank you for this informaton , I tried but don't even know what file to load, I tried one from Year 2016 , but not usefull . .
I had heard that some sites which are not compatible with El Capitan through Firefox , could be with Opera , but not still compatible with the Opera that I Loaded ,
and if I try to look at 2023 versions on this site, there are 5 Files to load , and I don't know how and which one to use or load !! 4 Autoupdates ?
But I loaded Opera_99.0.4788.9_Setup.dmg from 2023, but of course incompatible to use with my El Capitan =
Guess too complicated and for no result ,
