Secure Websites needing Update when Browser is already up to date

I have now had two websites that are having problems with a fully updated Firefox and they are telling me to update the Browser. Chase and now the IRS site is wanting me to update and I'm running 97.0.1 (64 bit). Win10 that is also fully updated.

Hi, this is because you are running software that modifies how Firefox identifies itself to websites. It told this site:

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:97.0) Gecko/20100101 Firefox/97.0 GLS/91.10.9719.20

That last part is non-standard and is breaking browser detection.

One possible culprit is Avast AntiTrack or AVG AntiTrack.
