I'm not currently able to sign into my UK account using this link: https://www.mozilla.org/en-GB/account/ When I type in my email address and click continue I just get a circular loading symbol going round and round forever. I'm able to sign in using the US sign in link for some reason. I'm not able to sign into Firefox overall though, so none of my bookmarks etc. are synced. I have tried on two different laptops a week apart with the same results.
