Firefox Community Forum

look, i have no idea if this is a bug, but i have been dealing with this for over a month now. i even have tried to use what was suggested, still does it. it all started AFTER i used mozilla sync, now for some reason it forces me out of my accounts every time i try to restart my browser, forces me to log back into them, then does it again if i close out mozilla at any point after to make sure it isn't about to sign me out another time.

it's getting frustrating because i am tired of losing my history, my bookmarks, and my extensions. this is also reaching a point i am considering changing web browsers because it won't fix after trying the suggestion given before of deleting the files.

This is by now more of a complaint rather than a question, since I already "solved" my problem (manually, by redoing all the affected changes). I'm writing this here in the hope it gets considered/solved in future Firefox updates, and I couldn't find a better place to write (sorry, I also didn't look too hard, since I've already lost some time manually "fixing" the scramble).

The context: I use Firefox currently in three different computers, with a login to cross-communicate my settings, add-ons, and specially, my bookmarks. I use Firefox bookmarks so much that most of my job is saved within them. One of those computers I hadn't used Firefox in a while, and yesterday I had to, and had to log back into my account in that machine. First weirdness was when it took so long to sync my favorites that I gave up and went to do something else. Then this morning in my main computer I realize that old bookmarks from that computer had synced BACK to my main one.

The problem then, is that instead of syncing the bookmarks by the last changes made by me, it got old bookmarks from the old login. I wonder if I had been using a new computer if the system would consider "no bookmarks" as my new bookmark list... sorry, I jest. I know the system apparently only brought bookmarks back and (as far as I know for now) didn't took them away (but it should, since many were deleted or moved for being no longer useful), but I think this whole experience shows that the system should be looking at individual changes by timestamp to each one, not whenever the whole set was saved, and specially: do not save a set BEFORE syncing.

Plus, this made me wish for an option to undo synchronizations or save a current set for later reboot, so we could have more control over it.

I really use these bookmarks a lot, and they're basically the biggest reason why I stick to Firefox.

Recently I uninstalled then reinstalled Firefox on my Samsung A71 because I couldn't remove a timer I set on the app. I continued using Firefox on Android as usual for about three or four days but tonight I discovered that my Android history isn't syncing up to Windows 10 Firefox on my HP Pavilion. I signed out on Android, then signed back in again but my Android history still didn't appear on Windows. I tried several more times, using both the QR code and my email. I then uninstalled FF on Android and reinstalled and signed back in again but only a few items appeared in my Windows history. Android won't show me my current tabs on Windows as I type this either and the sync now button is doing nothing. Is there anything I can do fix this?

(P.S. both versions are up to date)

Signed on to same mozilla account on old and new computers. Set each sync for bookmarks, passwords and such. Both computers are shown as signed on, but none of bookmarks appear in firefox on new computer.

Hi, I’m having trouble keeping my bookmarks in sync between my Windows laptop and Android phone using Firefox Sync.

I’m logged into the same Firefox account on both devices, and Sync is turned on. However, new bookmarks I add on one device don’t appear on the other.

I’ve already tried:

Signing out and back into my Firefox Account

Forcing a manual sync

Checking that both devices have the latest Firefox version

Is there a way to manually trigger a full re-sync or reset the Sync database without losing data? Thanks in advance! 🙏

I've ALL Mac. Desktop, laptop, i-pad, i-phone - oh, and I've got a Lenova for an exercise program that's in the mix. I can't seem to get any syncing done. I see notices that it's happened, but the tabs on none of the devices line up. I also tried syncing with/to/from my iphone. I got you QR Code and had to use the Iphone camera to scan it in. I got a message that I have to do it from within Firefox - but all I can get there is something KROLL. And that's an internet URL/page. I can't find a way to scan the QR code with that app hogging my screen. I've attempted to scroll/dump that tab but when I open up Firefox again...it's still there.

On my windows 11 machine, Firefox requires me to re-log into my Mozilla account every few days (there is a yellow triangle on the Account extension, which when clicked, has me to log into my Mozilla account). I have tried several troubleshooting steps:

1) Create a new profile and set it as the default profile 2) Completely uninstall and reinstall Firefox using the steps in the following article, including removing user data. https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

I'm using Firefox on a Mac and my iPhone and I don't experience this issue. I am logged into my account on both devices.

Thanks,

Paolo

Old bookmarks not showing up in Firefox on new computer. It seems to merge all Edge bookmarks onto new Firefox on new computer. Is there away to get old Firefox bookmarks backed that were synched?

I tried using Firefox on a new device, I wanted to sync with my previous settings to just restore them, I was unable to remember the password at that time so I reset it, after resetting it it still didn't work and different problems came up so I tried fixing it in a different way. Long story short im unable to connect my current profile (which I used previously with that email) with that account, so im also unable to start any ways of syncing as only this message appears

"This profile was previously synced to a different account

To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using email, create a new profile."

Right now im just using a backup which basically restores the profile, but if im doing something on one device it shouldnt sync to the other one, whats the best way of fixing it, is there a way of desyncing the profile with the mozilla account or start a fresh profile but slightly alter some values so I can use this one?

Kind Regards

I have been using Firefox for years on my Mac Mini and MacBook Pro, sync has never been a problem.

Now I inherited a Dell laptop, after reinstalling Windows 11 I installed Firefox and logged into my account as normal, and then switched back to using my Mac Mini. The next time I closed and then later reopened Firefox on the Mac Mini, Firefox had logged me out of every website, forgot my entire browsing history, passwords, bookmarks, everything. Its all gone with the exception of 4 of my 16 links on Firefox Home.

So I spent an hour fighting MFA, etc. on the websites I use the most, only to close Firefox and have it log me out and forget everything again. That is now its behavior, it loses everything every time I close the app. It does remember my toolbar settings, and those same 4 links on Firefox Home. i rebooted the computer and the problem remains.

Firefox is still logged into my account, it just doesn't sync or remember anything. Doesn't save cookies, history, nothing. Every time i relaunch the app, Firefox home is back in its default state

I also still have an instance of Firefox open on my MBP, I am now deathly afraid of closing the app for worry it will do the same. I also am afraid of using Firefox on the Windows computer, I absolutely cannot break this more.

How do I fix this this quickly and prevent it from ever happening again? I am getting absolutely buried in computer problems at every turn right now and nothing's getting solved. Every fix for weeks not only fails, but inevitably creates a new problem and I'm sorry but I'm going a little crazy and I really need a break.

Thank you.

I've been using Firefox on device A computer in the evening, and the next day, after opening device B computer from sleep, a tab was open from the device A session (along with some older tabs I kept open, it was placed at the most right location). I am 100% certain I did not have that tab open from previous session on B.

The only way this tab would be able to appear on device B is if I somehow triggered a "send tab to device" functionality when working on device A, however, I am 100% sure I did not. Seeing how I would have to right click the tab and select a submenu to trigger that, it seems essentially impossible that I did that by accident.

Q: 1. Is there a keyboard combo that could be accidentally hit that would trigger Send tab to device? As far as I could research, there is no such shortcut. 2. Can a website trigger this API and perhaps I approved it by accident? I would definitely also notice this. 3. Is there a sync audit log I could check on either device to see if a tab was synced? I found about:sync-log but nothing really useful in there.

This event is so weird that I am considering secirty aspects or a potential exploit vector..

Recently I lost my earlier mobile phone and purchased a new one. I tried many times but every time the pairing/sync to my new device is failing. I am tired of this. Can you help?

Dear all, I am searching the mozilla knowledge base and the internet, but I cannot find a solution to a simple problem. I used everything. Example: I would like to have my data saved and synchronized between devices after logging into my email so that I don't have to keep logging into the selected website. I also want websites other than exceptions to be deleted from the history after closing the browser. On computer A, I installed Firefox, created an account, and then added specific websites to the exceptions so that cookies would not be cleared when closing the browser. The account was synchronized. On computer B, I logged into my Mozilla account, and these saved websites require me to log in.

Thanks for your support.

Best regards, Maciej
