I sync my bookmarks and tabs via Mozilla sync. It works so far, as the bookmarks and open tabs from iode devices are visible on non iode devices, but if I want to open a tab from another device, nothing shows up, it says I should login. I am logged in, but don’t see any tabs from other devices. Firefox shows the synced tabs, so I guess there is some settings in the iode browser which Blocks the correct sync
I have the same issue but didn’t look too deeply into it. It used to work, so I think possibly some of the iodé browser tracking removals may be blocking something?
