Hmm. Based on the comment, I assumed it would work for most browsers.

frontend/discourse/scripts/browser-update.js

2834cc795


      
          // retrieve localized browser upgrade text
          var t = window.I18n && I18n.t("browser_update"); // eslint-disable-line no-undef
          if (!t || t.indexOf(".browser_update]") !== -1) {
            // very old browsers might fail to load even translations
            t =
              'Unfortunately, <a href="https://discourse.org/about#browser">your browser is unsupported</a>. Please <a href="https://browsehappy.com">switch to a supported browser</a> to view rich content, log in and reply.';
          }

What is a “very old” browser? Is it possible that

is, while the latest Firefox version working on Windows 7 (I think that’s 115) isn’t, so the customized text would work there?

Edit: Seems it does not
