I am signed into the OLD Firefox sync with my correct password and username. I want to update to the new sync because I've got a new PC that i need to sync to and the old syn won't accept adding new units anymore. However, when I try to log in to update Firefox, it tells me that my password is wrong, which I know it isn't. I read that passwords set before 2012 may not be accepted, so I asked to have my password reset and Mozilla is supposed to send me a reset email. I've asked for the reset email multiple times, but they're never sent one (not in spam folder, I checked). Other have had this same problem, how can it be resolved? No way to email Mozilla support for help (grrr)
