This version of Firefox is no longer supported.

I just upgraded to F27 (today). Firefox reports as version 57.0.1 (64 bit) for Fedora.

When I open Gmail in Firefox I get a message: "This version of Firefox is no longer supported. Please upgrade to a supported browser." I've been getting this message since just before upgrading to Firefox 57.0 (a couple of months ago?)

Is this just something Gmail isn't reading correctly? or should I be concerned (instead of merely annoyed)?

I have no problem acessing gmail on my Fedora 26 with the most recent Firefox (57.0.1). Are you talking about some sort of gmail plugin/addon for Firefox?

Check your date and time in the system...

usually SSL doesn't work if date/time is incorrect but those errors should look different, no?

Do you have some extension that changes the user agent string? Try going to http://www.useragentstring.com/ and see what it says.

When I run http://www.useragentstring.com/ the box says I'm running Firefox 31 - not 57... it gives a build date of 20100101, Ancient history. The machine isn't that old. Any ideas on how to change it?

It looks like the problem comes from the User-Agent Switcher I use to emulate Android on my computer. It uses the string: Firefox Running on Linux - Mozilla/5.0 (X11; Linux i586; rv:31.0) Gecko/20100101 Firefox/31.0

I'll try removing it.

thanks

There is User Agent Switchers out there that let you emulate more modern versions of Android (and other OS)
