Get your taxes done using TurboTax

I've been trying for over a week to log into my long standing Turbo Tax account, been using the desktop home computer, Firefox browser online version of Turbo Tax for over 15 years now. I can only get as far as the page that says I need to update my browser. I've always used Firefox on my home desktop, never an issue before. After 'updating'...nothing different. Won't let me in. After trying repeated 'updating' each time Intuit asks me to do so...nothing.  This is January 18, 2020 so it's NOT an old problem. Any clue about what is going on here? Oddly enough, T.T. / Intuit allowed me in the site to post this help message, but not into the actual 

site so I can get to work.
