Firefox Community Forum

I have a new installation of Ubuntu 24.04.1 desktop, all default install options (selecting "normal installation"). Upon first login, I'll open firefox, click the sync button and log in. After putting in the code emailed to me and 2FA, my login/sync status show that it's active for just a fraction of a second and then a yellow triangle appears. Clicking the sync button shows my email account with status of "Account Disconnected". However, on Mozilla's account settings web page, it says I am signed in to the new Ubuntu install on the connected services page.

I have attempted to sign in half a dozen times and see the same sequence of events: A successful login and then "account disconnected". I've changed profiles, removed the signed-in profile from mozilla's accounts page, done an apt remove/install of firefox while deleting all profiles, and deleted and re-installed Ubuntu completely from scratch. My system date/time is correct and I don't see any cert errors when browsing regular websites with SSL.

Looking at the sync debug, I see many invalid token messages, with 'invalid token error, but account state appears ok?'. I've pasted them here: https://pastebin.com/squXBebF

I can replicate this by installing ubuntu (https://ubuntu.com/download/desktop), opening the pre-installed firefox and attempting to log in.

bold textdownloading only produces " .part " files in my downloads directory. I had previously attempted a large file download but error message said it was not completed. Now cannot download anything
