I have a MBP running OS Sierra (10.12.6).

I've exported all my bookmarks & Passwords ready to import them later.

I've downloaded the extended 115.40 version of Firefox. I've deleted the 'old' versin of Firefox and opened the esr and I see the bookmarks are still there... so what did I do wrong?

I'm still getting the 'This browser version is no longer supported' Error

Thanks g

You're probably getting it from a specific site, that no longer supports the legacy macOS as a whole?

Is that an error or just a warning, can you still use 115

There are some tips how to cheat and pretend you're running something newer: support.mozilla.org/questions/1591289

Hello, Oh, I can still use the browser just fine. It's just a 'warning' sign at the top of the GMAIL page that says, 'Upgrade to a supported browser'... And since I like Firefox... I tried to do that... alas, the warning still comes.  :-(

thanks g

Yup so the Gmail warning is specifically covered in the link I shared — they're working fine in ancient browsers, so the addon to change your versions would help to get rid of the nag bar.
