Whenever I install a new system with a GUI — which is quite often as the responsible for the network — it's unavoidable to have Firefox on it since is hit and miss with uBO and the Chromium ones.

Except for the pages that load automatically on install, before I open the first page, and before I enable sync; I make sure to match my settings on other Firefox instances first. I even set several in about:config too; namely anything related to QUIC/HTTP3, encrypted DNS, and this relentless need Firefox has to navigate automatically to the HTTPS version of a domain as if they were always the same site. Technically speaking, they're not even the same server but I digress, when I finally enable sync it reverts all* the settings to defaults again.

I thought this was synced down from somewhere but recently I installed Firefox on an older system, I did the ritual with the settings, the candles, the about:config, the dead cat, y'know… the whole thing, and enabled sync. But what it actually happened was; I only logged in. Sync remained off. It read something like "sync off" in the setting next to the big blue button to turn it on.

Before I click the button, I opened a new window, and went to the settings again to make sure that the settings on the current window weren't stale. I noticed the reversal had already happened. Despite nothing had been synced I already was back to defaults.

I changed them back.

When I clicked on the button, the usual selection of things I sync was already done, I just had to confirm it and that was all. Once it finished, my settings were change to defaults… again! Albeit to a much lesser degree. The password manager turned itself on again, but not all the checkboxes below the main setting, one of the two Recommend, something-something while I browse was turned back on, I think Show search suggestions in address bar results was turned on too, and I don't remember if the settings for Firefox Home were changed, they often are, I don't use it at all, but it's rather easy to accidentally have the shortcuts from that page to prepopulate in the address bar drop down.

There must be one setting that prevents this, on Windows I think I have it under control (Firefox is preinstalled and preconfigured through Active Directory), that would be awesome if anybody actually used Windows, we only have it because our accounts are in Active Directory, but it does prove that it can be controlled. Most of the settings that have disappeared from Firefox are still available to Enterprise administrators and then some …which is a bit telling from the browser that allegedly champions privacy.

I want Firefox to let me navigate to "dangerous sites", so I learn early from my mistakes, not later when these protections have made me careless and it's riskier; to keep remembering on my own to keep my passwords fresh, not have that software crutch that relies on a third party service; to be a browser, not my operative system.

Although I'm not a dev, you can get as technical as you want, no need to dumb it down; if I don't understand it, I will be happy do my homework, just tell me how, please (and thanks.)

• not all but it feel like it: it's mostly those that use Mozilla's hosted services, I believe, such as the password manager and the like.

To sync a mobile device, the instructions say to open Firefox browser on mobile, from Menu go to Sign In, aim phone camera at QR code. The 3 lines at the screen bottom right (i'm assuming this is a menu but printing an icon labelled "menu" is less cryptic) offers no sign in opportunity.

My understanding for profile feature was that bookmarks, user preferences were seperated. However my Pinned websites on my work profile in my work computer is synced to my personal profile at personal computer.

Is there a way to avoid this or is this unavoidable when using the sync function.

Hi,

I recently had to reinstall Firefox. I made sure that settings etc were backed up in my Mozilla account, but I didn't realise that my custom search engines had not been backed up. I have about 20 of these custom search engines for work, so it was a pain to re-apply all of these. It's done now, but I'd like to know if there is a way to back these up for a quick restore on a reinstall?

There is no 'Search Engines' option in my Sync settings.

Thanks

Choices? I need to understand the App before committing my internet presence. Options to revert to Firefox/Windows, disable features I choose. Otherwise it just GQQle. Sync is already intruding on my preferences.

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

Dear support, I have 2 pcs and I need to enter sync password every time I open Firefox - start notebook. It works fine on the second pc and password is remembered. How to solve it? Because I need to write sync password every time, open all cards etc .. OS - win11 pro, Firefox browser versiono 145.0.2 64bit, no 2FA in firefox. Thank you. Mike Hrubjak.

How to make Firefox my default browser on my new computer a Windows 11 computer. I’m to the point where I’ve got a pop-up window, which says sync Firefox on your phone or tablet. I am asked toOpen Firefox on my mobile device. Then Go to the menu and tap sign in. That’s where I am. Now I’m asked to tap “ready to scan” and hold my phone over the code. Unfortunately, my Firefox app does not show a ready to scan option after I get to sign in. Help!!

Good morning, the "Payment Methods" section has disappeared. In its place, I see a link called "Manage passkey in system settings," which takes me to the Windows 11 Passkey section, which I've NEVER enabled!

If I create a new profile, the "Payment Methods" section appears as normal, but when I link it to my Microsoft account for profile sync, the "Payment Methods" section disappears and "Manage passkey in system settings" reappears.

How can I fix this? Thanks

bol it's really frustrating because again I only have one device a Motorola cell phone and I don't have any kind of computers or laptops or anything else and it's always talking me to sync my tabs for my other devices and this and that and it's really frustrating because I don't work I'm on ssti I don't go to school and it's always telling me that my I have an administrator on my account that's for my work or school or something like that when all it is is hackers have taken over my phone and hijacked everything in my life because of my old roommate David Floyd Lee

I have 150+ tabs open of Firefox Android. I would like to close some of them conveniently.

I have synced my tabs and on desktop I have now 2 ways to access them.

1. On the left "Synced Tabs". This is very nice, I can filter by text and open the appropriate tab. Now I decide, I want to get rid of it. Closing on closes on Desktop, which is expected behavior.

2. Using the "Show tabs on other device" icon. This lists all my tabs, some directly, some in sub-directory "inactive". I could now click the x button next to the tab and close it. But: Having 150+ tabs open, it is very difficult to find the open tab in question. I even have to click "Show more tabs".

Basically I would like to use version 1, find a tab, right click and select "close synced tab".

Am I missing an option?

I made the mistake I will never make again of signing into a Mozilla account in Firefox. Suddenly everything about the browser was completely different. I realized it had synced to my primary computer without asking me a [expletive] thing about what I wanted to sync or if I wanted to do that now.

How do I unsync the second computer so that Firefox goes back to the way it was before the unexpected forced sync? I had those settings the way I wanted them for a reason.

Hello Firefox community, I use Firefox Desktop on two devices — one for work and one for personal use. I’d like to have different bookmark toolbars on each device, but they keep syncing and becoming identical. Is there a way to prevent this (without turning off Sync entirely)? Or is it simply not possible to use more than one Firefox Desktop setup with different bookmark toolbars under the same account? Many thanks! Eva

I would like to know how I can choose the aster PC from which firefox snchronizes on other PCs and what to do, that it does not change direction when i am in vacation with the non-master PC

The bar across the top (has "View recent browsing across Windows and devices" at the left end) has far too many remembered tabs. It's only happening on this platform (my wife's) and not on mine. Both running Windows 10, although I'm switching us both to newer platforms because of Windows 11.

There must be some way to turn off that bar in this platform, but I can't understand all the Firefox on-line help documents, because there's no place where there is a diagram indicating what that bar is called.

If I have edited the passwords file and bookmarks file and saved them to a folder via export feature. When I import the edited file into firefox how can I make that the master file and not have the other instances of firefox sync all the old data back to the master one I edited? For instance I have FF on android, linux and windows, if I import the edited file to the windows instance what is to stop the linux from syncing back to the windows machine? I have had this happen previously where a newer instance of firefox overwrote the bookmarks and password files. Will I have to delete all bookmarks and passwords and import them from the new edited file on each device?

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.
