I need assistance after updating to Firefox ESR
When I open my Gmail I see the following message: “This browser version is no longer supported. Please upgrade to a supported browser.”
So I Downloaded Firefox ESR as suggested by Google and then I moved the Firefox app into my applications folder, but then got the message that "a newer version already exists, do I want to replace it with the older one I’m moving? Or keep both", so I kept both.
However when I go to my application folder I only see one Firefox icon and when I opened my Gmail again I still see that message “This browser version is no longer supported. Please upgrade to a supported browser.”
I also see that Google is saying that Firefox doesn’t support “offline access to Gmail” what does this mean?

Btw with the old EOL macOS 10.13 to appear to be running, the most current Firefox you can use is Firefox 115 ESR currently at 115.34.0esr. https://support.mozilla.org/en-US/kb/firefox-users-macos-1012-1013-1014-moving-to-extended-support
Firefox 116.0 and later including the current 149.0 Release and 140.9.0esr requires macOS 10.15 (ten.fifteen) or later to run.
