Can't enter UK phone number to sync

more options

I am trying to sync my Windows Firefox to my mobile phone Firefox. I have set up sync on the mobile. But I can't enter my mobile phone number on the Windows Firefox. I get "invalid phone number" whenever I enter my UK mobile number. I have tried it with the leading zero. I have tried it with +44 followed by the number without the zero. I have tried it with 044 followed by the number without the zero. I have tried it with 0044 followed by the number without the zero. I have run out of ideas. Can anyone help?

Chosen solution

Edit: Oh, did I read that backwards? Sync is already set up on the mobile, and you need to connect your Windows Firefox to the same account? I don't think your mobile number should be required for that. I think you should be able to connect through the Options page, Firefox Account panel.


I think what gets sent to your mobile is just a link to Firefox in the relevant app store (Apple/iTunes AppStore or Google Play), so you could install the Firefox browser of your choice without the link by going to the app store and searching for it the usual way. Then set up Sync on the mobile app through the menu or maybe through the home page or new installation page if there is a message for it there.

That's insane that Mozilla would require the phone number to be in the country code of your location. It's 2019, people travel and move around and don't change mobile numbers! I had to use a VPN scrambler in order to get it to accept my UK number.
