Hi everyone, I’m using multiple Firefox profiles to separate my work environments (e.g., “Work”, “University”, “Personal”), all linked to the same Firefox account.

What I would like to do is:

Use the same Firefox account across multiple profiles to keep extensions, passwords, etc., synchronized.

Sync bookmarks only within the same profile, so that bookmarks from the “Work” profile do not appear in the “University” profile and vice versa.

Continue to be able to edit bookmarks from different devices (home or office) while keeping them synced only within the same profile.

I’ve looked into Firefox settings and sync options, but it seems Firefox syncs everything across all profiles connected to the same account.

My questions:

Is there a native way or any setting to have bookmarks synced separately per profile while using the same account?

If this is not possible at the moment, could this be considered as a potential feature for the future?

Thanks for any suggestions or guidance!

Every time I log in with my Firefox account on a new device, the exceptions I set under Privacy & Security -> Cookies and Site Data -> Clear Cookies and Site Data When Firefox Closes -> Manage Exceptions disappear. This should definitely be included in synchronization. Let's be clear: I don't want my cookies saved so I can log into all my accounts every time. I just want my exceptions to be included in synchronization. Firefox could also develop a tool for this: an add-on to easily add websites to exceptions. I don't want to download an external add-on and install it every time for something this simple. Nobody wants that. I also think all my settings should be included in the synchronization scope.

Tried to sign in to Firefox on a Linux laptop; searched for a password and finally found it under "a" for accounts;maybe my error. Tried to sync. bookmarks etc. from Android phone and it suggest two non existent menu options: Sign in and - i've forgotten; Sync between devices maybe; anyway nothing resembling either was in the menu so it is at least satisfying to know you can delete a browser with no concern that anything useful or even functional is to be missed.

Multiple profiles are for different behaviour on the same, say Linux device, with different settings How does this interact with syncing? E.g., I want different settings, but the tabs should be synced?

On windows 10, Firefox Browsing/surfing was slow so I did netsh winsock reset and ip reset etc.

But thereafter few sites in-page notifications aren’t loading properly like facebook notifications, forum notifications, amazon page etc.

Nothing works irrespective of cookie or entire history deletion.

I had to fiddle with the networking settings few months back so unsure what are the stock FF settings- what they should be like. I wasn’t able to find on google.

I did performed a FF refresh and even created a now profile and that works absolutely fine!

But the moment I log into my FF cloud account for re-syncing all add-ons, bookmarks etc and dang the issue reverts. So I think 110% the FF account sync is restoring back the network settings I did some time ago overriding the default ones hence the good up.

All other browsers like edge/chrome are working fine.

What I want is-

   * The default FF network settings which I can correct and re-sync back to my FF cloud account.
   * Or a way to only restore bookmarks and extensions/add-ons and nothing else from the cloud account.

I have re-synced by desktop and laptop today, but I am unable to sync with my Android phone.

The instructions say to bring up firefox on my phone and click sign in. But whenever I type 'firefox.com' or 'firefox.com/pair' into my firefox browser on my Android phone, I get a version that offers to download firefox! I've been using it for years. I cannot find a way to sign in as instructed.

This has been a very frustrating experience, and I generally expect Mozilla/Firefox to do better.

On 10/15/25, for whatever reason Firefox literally disappeared from my laptop while I was online. Thankfully I had another browser to get Firefox reinstalled, but in getting all that done a file called Old Firefox Data with 68x5bhgm.default-release was deposited on my desktop. Today I discovered I had no bookmarks in Firefox on the laptop, so thought, fine I’ll just sync it up with the iPhone. The directions say open Firefox on your mobile device. Go to the menu and tap sign in. But the 3 dots do not show a menu to click on Sign in. So I can’t sync anything to get bookmarks back on the laptop. And all these problems began with the latest Firefox update to 144.0 on the laptop. The iPhone Firefox is still on update 143.2. Anyone have any ideas other than restoring to a prior date?

I am trying to sync my new laptop with my ipad. I am using Firefox with Duckduckgo as my search engine. Instructions are to click on the search window and a scan icon will appear to the right but I don’t see it. Would duckduckgo be effecting my ability to do that?

thanks

I cloned my 2017 intel iMac onto an M2 Macbook Air. Since one week I use them independently and keep Firefox synchronized. I changed their names in Firefox sync. But under "connected devices" at first there was only one of them, depending on which one I refreshed the open window first. I tried to separate them by logging out and in again, but now both are gone in the list. Nevertheless, syncing works. I hope my Mozilla account won't get garbled up.

Trying to sync my old PC to my new PC by using sync to my iPhone and then back to the new PC Following online instructions for phone to PC but the instruction to go to the menu and tap Sync and save data does not exist. I’ve already downloaded Firefox on my iPhone but it keeps asking me to download Firefox Very frustrating. Please help, thank you.
