Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
But for people who dont want to sync this ... it would be good to have an option to not sync this data for specific devices.
Add customization of toolbar to sync
It would be nice if the taskbar layout and themes sync between devices like cards or history.
(Note: a similar idea has been merged into this thread)
The product team here at Mozilla recently kicked off a discussion to gather feedback on this very topic: Upgrading your computer and moving your Firefox data
We are working to understand and improve this experience for Firefox users...and would love to hear your thoughts. Feel free to jump in that thread and answer any of the questions.
Looking forward to hearing more of your ideas 🙌
This would be nice, even as an opt-in option where you're prompted upon connecting devices or something.
And as a side note, please implement this for search settings as well. Every other desktop setting seems to synchronize, why make me have to manually reconfigure my search engines every time?
