You appear to have a user agent that is modified by Avast/AVG Anti-Track (Firefox 97.0/aN8ebOuz-13) that could cause problems on a website, so if you use this software and notice issues then try to disable this software. You can contact Avast if their software causes problems for you. We can't do much about this apart from identifying Avast/AVG Anti-Track as a possible cause.
