firefox for el capitan
Old MacBook Pro. Must use El Capitan to run Photoshop CS4. I have read that Firefox 78 will run on El Capitan. But when I search for a download site, one of two things seems to happen. Either the site indicates that I am getting 78 but I actually get 96 or I am directed to the long Mozilla list of past Firefoxes: https://ftp.mozilla.org/pub/firefox/releases/
If I click on 78.0.1 I get a further list of about 20 links. One of them is mac/. Clicking that gives another list of links. I am getting nowhere on downloading Firefox 78 or some other Firefox that will run on this MBP. Help greatly appreciated.
