old support account is locked and trying to create new is problematic at least.
so, im lucky enough or ignorant enough not to have used the support forum for about a year now. so, by downloading the latest thunderbird update, things got a bit sideways and i ended up here for instructions. now, i do have (had) an account with the old system. https://support.mozilla.org/en-US/user/georgeka thats me!. it is described that it would be somehow linked to a firefox account or something. didnt happen. i decided to manually re-enter my account info to see if i could do it myself. nope. decided to create new account. using chrome i press the login/signup button, but i am taken to a page dedicated to sign in. there is NO register and NO other info. when i type my email to see if i am taken to the next step: Enter your email -> email ZZZZZZZZ@ABC.CDE -> Continue to Mozilla Support, i get the error, Missing parameter: email while the mail shows up on the box. different mail, same result. goes no, futher.
using firefox 88.0.1 64bit, i reach the same point but when i type the email, i am shown the login / reset page.
