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?

Isisombululo esikhethiwe

Thank you James, I've now downloaded the current Firefox and hopefully it should solve my problem, although I'm still seeing the message about needing to update at the top of the Firefox interface. I assume my updated version is running so I'll just ignore the message. Regards John

Hello

These similar discussions https://support.mozilla.org/en-US/questions/1570596

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.
