reCAPTCHA not working on "frozen" Firefox version on Windows XP

[sdsearch]

reCAPTCHA says it only works with the latest two Firefox browser versions.  What it doesn't realize is that browser versions for Firefox are now separate for Windows XP (which my company still uses) and for "modern" versions of Windows.  So it refuses to display reCAPTCHA, preventing me from logging into some sties (such as www.bestwestern.com).  I do have the latest version of Firefox for Windows XP (52.3.0 32-bit), but reCAPTCHA refuses to recognize that as being "one of the two latest versions".  Then as a "solution" reCAPTCHA invites me download a newer version of Firefox, which doesn't exist for WIndows XP!

Is there any way around this (other than by using another browser)?  Firefox is the browser in which all my passwords are saved, so that's why I ant to use it for such logins.

Or if there is no solution (other than using another browser) for Windows XP (and presumably older computers too), the reCAPTCHA site should at least document that, instead of claiming it works on Firefox.

And the same issue I think may exist with IE.  The latest version of IE does not run on Window XP as far as I know.

And Chrome keeps telling me (on Windows XP) that support for Chrome on XP is soon ending, so will Chrome end up frozen too, meaning reCAPTCHA will soon not work on any browser on Windows XP computers?

Thanks.

You aren't going to find anyone willing to support development, testing or even documenting for an operating system that hasn't had support from it's own creator for more than 3 years.

Your company is going to need to bite the bullet and upgrade their systems. The only alternative is to just accept that there are things you can't do and the list will only grow as time goes on.

By the way using an operating system past it's end of life is putting the business at great risk for malicious attacks.

Good luck,
