Logging into Mozilla account on Zen reset some settings that were enabled for my Firefox install

[lajawi]

Very simple, I installed the Zen browser today to check it out, while Firefox was still installed. I logged in with my Mozilla account to transfer things like history, bookmark, and add-ons, only to realise later on that that caused my Firefox settings to break.

In this specific case, I lost all of my open tabs, because Open previous windows and tabs got turned off while I logged in on Zen.

Has anyone else experienced something similar?

I have had the same experience. The way FF sync works, it seems to think there's only 1 global/universal installation of FF, and so it doesn't differentiate between FF vs Floorp vs Zen vs ....

The only dimension that it seems to think of is that the same browser (and potentially the same version of said browser) are installed on multiple machines/phones/etc. Thus, the latest machine to connect to the sync server basically wins.

So, basically, this is not an issue that Zen can control - its more "upstream" ie in FF and more specifically in FF's sync server + implementation.

You're saying, as long as I use the same browser across multiple devices, even multiple desktops, it won't reset or change settings, but as soon as I use another browser (i.e. instead of Firefox, Zen), it will reset?

I understand this is not the matter of Zen or any other browser forked from Mozilla Firefox, but it's weird and counter-intuitive to me that settings that get synced across the same browser on different devices would be reset when using a different browser, that uses the same account system with the same settings. I'll be sure to try and forward this feedback to Mozilla themselves whenever I can.
