How to update firefox to use on Google docs

Would you be able to attach a screenshot here with the error message? Thanks! They just might be confused, but I'll try to see how to get to the bottom of their confusion first. I see some dubious identification logged with your question so I'd like to understand that first — do you perhaps run your iOS device in some "lockdown mode" or use a VPN that would have a feature of changing the connection signature, fingerprint protection or something like this? If you go to www.whatsmybrowser.org in the affected browser, could you please paste the shortcode this site gives you in the blue header (contains no sensitive data) here for further inspection? Thank you!
