that site password reset is broken so i can’t even test this. i have been trying to reset my password for it for ages with the forgotten password link, and it just loops me through the password change telling me i need my original password, which i obviously forgot, since i clicked that link! (it was in my old company password vault which i don’t have access to now).
edit: oh now it lets me login on the site directly even though ubuntuOne says my password wasn’t changed and kept looping me through the process. i don’t get it. maybe just some cacheing issues with identity provider 
anyways, i just tested this with latest firefox and ubuntu 24.04 and no issues or errors (other than above, which could have been between my chair and keyboard lol)
