    Starting yesterday, I find myself no longer able to access MDL using Firefox
    MDL (whitelisted) Now requires me to complete a Captcha (for temporary access only)
    The Captcha however, will not complete (Literally, WILL NOT complete)
    Cleared Cookies, ran anti-virus etc... nothing

    Any suggestions?

    Try Edge or IE or another browser.

    I use only Firefox and log in\log out MDL without a problem.
    So check you installed addon, some of them may block access. Clean cookie and cache.
    If non of this work try reset to "fresh" Firefox, create a new profile.

    Run FF in safemode to disable addons and try again

    Faced exactly the same issue yesterday, using both portable Chrome and IE. Unlike @drew84 I managed to complete the captcha, though. A message on the opening page was a bit scary: "Why is this happening? You might be infected..." So run a couple of security scans anyways.
    Today everything is back to normal: direct access.

    All of these details you have provided indicate that your IP address is not permanent, it is not stable.
    Do you use any VPN or other floating IP address?

    Sometimes, accessing MDL in Fire Fox, it behaves weirdly (Cloudflare alert) when using a VPN . But it becomes normal when one is using the real IP. (my experience)

    Depends what your settings are.
    If I harden too much, I also get it, and it's impossible to do the captcha because of addons mostly (or about:config tweaks).

    (OP)
    IP settings were unaltered

    Whilst I use a VPN there are a number of Whitelisted sites incorporated (Including MDL)
    Have not encountered the issue previously, and all was working fine yesterday, until it wasn't
    The only change made was to the browser itself, and only after the issue surfaced (privacy Pass add on, suggested by the captcha page)

    I have just used the firefox 'refresh' feature (add ons removed and firefox reset to default) and all appears fine
    This would lead me to believe that the issue may have been as a result of an update to one of the add ons, can't be sure until reinstall
    Edit: All add Ons put back and all still OK

    The issue, although resolved, the question as to what happened itself remains a bit of a mystery

    Thanks to all for input

    Found the culprit (Firefox about:config tweak)
    privacy.resistFingerprinting
    I have always set this to true, but starting sometime on Saturday this tweak (in my case) now causes the captcha issue with MDL
    True - Can't access MDL
    False - Can access MDL

    May not be the complete answer though, as it could be a compatibility issue with uBlock Origin/uMatrix
    which handle the restricting of fingerprinting

    Nothing to do with the ip in most cases,its the tweaks applied to the browser( be it firerfox or chrome).By "tweaks" i mean spoofing various parameters blocking or turning them off.

    The setting is for making your browser more non-unique/general (blending/masking). Unfortunately, it causes websites doing sniffing to not recognize the browser anymore. Services like Cloudflare or Google fingerprint your browser to verify you're not a bot, this fingerprint is used to prevent further Captchas. If you resist fingerprinting, the side-effect is what you're experiencing.
