I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

We apparently lost power sometime during the night. When I turned on the monitor and opened FF, I got the error message that it had crashed. As my subject line says, I lost all my tabs, the pinned ones (probably about 10) as well as the open ones (probably between 10 and 15). I also lost all my history. I can't use the 'Restore Previous Session' because it doesn't give me that option.

I've restarted Firefox and also rebooted my computer...still nothing happens. It's up to date, version 133.0. But I have no history beyond this morning. Is there any way I can recover those tabs or history?

And in my FF Settings, there's a link at the top that says "Your browser is being managed by your organization". I don't have or belong to an organization. When I click on the link it takes me to another page that says it's "Active" and there's a huge list of "Documentation" that apparently involves a lot of code. Can you please explain what all that means? Thanks so much for any help!

I'm not sure what type of issue this is, so hopefully I’ve posted it in the right place!

Devices:

• Firefox version 133.0 on 2022 M2 MacBook Pro OS Sequoia 15.1.1
• Firefox version 133.0 on iPhone 16 Pro Max iOS 18.1.1 (*for reference, of checking issue, not where issue is occurring)

Issue Breakdown: While updating my bookmark's tags in Bookmark Manager, my tags all but disappeared and other strange things started happening.

• My tags aren't in the sidebar menu of the Bookmark Manager at all. See Screenshot 1.
• Already tagged bookmarks retained the tags, but I’m unable to edit, add, or remove bookmark tags at all. When the bookmark is selected, the bookmark’s tags, nor any other tags, appear in a list under the bookmarks tags. See Screenshot 2.
• I can locate all bookmarks with the same tag by searching bookmarks in the Bookmark Manager.
• I can move and rename pre-existing bookmarks.
• I can add new bookmarks (confirmed by the blue star beside the address bar on the main browser after exiting and re-entering), but I cannot find those bookmarks anywhere in Bookmark Manager.
• My mobile bookmarks folder isn’t shown in Bookmarks Manager, but I can view 11 bookmarks in my Mobile Bookmarks folder on my phone’s Firefox application.

I’ve tried the following:

• restarting Firefox by quitting the application
• refreshing Firefox through the browser [https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-se...]
• restarting my computer
• clearing the startup cache
• clearing the cache [https://support.mozilla.org/en-US/kb/how-clear-firefox-cache|link]
• restarted in Troubleshoot Mode [https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubl...]
• uninstalling then reinstalling Firefox software

I have no idea what is wrong with it or what is going on. What else can I do?

I opened firefox profile manager using 'firefox -p' and tried to delete one profile...firefox deleted all profiles except 'default' and 'default-release'...even with them firefox renamed them with some number suffix and created new folders with the same name ('default' and 'default-release')...I have checked /home/ubuntu18/.mozilla/firefox folder...all profiles/folders gone...UPDATE: As I was typing this there was power loss, firefox deleted old 'default' and 'default-release' too...How to get all profiles back?

I have set up a new Windows 11 PC (brand new installation). I installed Firefox and tried to sync, because I want to copy settings, history etc. from my Windows 10 PC.

However, it fails. I enter my password, then it asks me to enter a code sent to my email. I enter that code, and it says "Bad request" and "Something went wrong. Please close this tab and try again."

It's not the most helpful error message. All I can do is retry, but after 20+ attempts, I think there is something wrong with the 2FA.

I'm able to successfully log in to https://accounts.firefox.com/ on the browser without any issue. That uses a 2FA code from the authenticator app on my phone.

Any ideas? Is there a better way of copying my browser to the new computer? I was thinking of just copying the Firefox profile folder, but I don't want to end up with it duplicated since my Windows 10 PC is still active.

Hello. All tabs in the browser on the PC are missing. I sent the tab from the mobile version of the browser, via the share with device button. After a while, I sat down at my computer and turned on the private version of the browser. A minute later, the standard version of the browser opened with the tab I had previously sent. But all the other tabs that were in the PC version are gone. In the usual case, when tabs disappeared when opening the private version and closing the standard version, you could use the "restore tab" command to open the standard version window with the tabs closed. But in the situation with the sent tab, this does not work. In general, I would like a solution in which, when the private window is open and the standard window is closed, the tabs on the standard window are not reset.

Background: I've recently (few weeks ago) changed my email address for my firefox account. The original address became a secondary address. Then i deleted the secondary (old address). So i was left with only 1 primary address. Now to the problem - today ive done a fresh windows install and i wanted to recover all my settings and tabs from my synced account. Ive logged in to my mozilla account using the new primary email (as for the old email when i try to log in it says i need to use primary email, so it should be still connected i think, but i can't use it to log in). Now after i logged in (using my new primary email) all my stuff was gone, as if it was a new firefox account. No old device connected, nothing. Ive literally checked my firefox acc today morning (and synced!!) to make sure everything's good and now theres nothing. I still have access to my old email if it helps, nothing bad happened there but i don't know if that helps.

Hello, A couple of months ago, I believe there was an update completed on Firefox and after that, I lost all of my bookmarks. I've since created a few, but the majority are gone. Is there any way to retrieve the bookmarks?

Thank you, Nicole Bechhold

I am trying to use a backup of my mozilla thunderbird messages but after having exported them (automatically put in a file called Thunderbird_profile_backup) I cannot open the file and use these important informations

My PC had to be reinstalled by our IT-Department. I restored my bookmarks from my Firefox account, but all the tags connected to the bookmarks seem to be lost. Are the tags not synchronized together with the bookmarks?

Before and after synchronization of bookmarks was activated. At least after the re-installation my Firefox is version 133.0.3 which according to Firefox is the latest version. Before the crash automatic updates for Firefox were activated.

I already tried to add a tag for a new bookmark to ensure that tags are displayed in the save bookmark dialogue. No the entry field for tags is displayed, but the tags of the existing bookmarks are still missing.

Is there any way to restore my tags?

My previous post seems to have disappeared, so will try again. I am 85 years old and have been using Thunderbird fo over 15 years with out any problems. Afew days ago I tried to send an e-mail and didn't have any "Send" button. In trying fix, I some how deleted my contacts sidebar. I sill have my addresses book. I have tried everything to retrieve them but no luck. I tried removing Thunderbird and reinstall, but it comes back the same. I would appreciate an guidance in trying to resolve my problem. Thank You

I'm trying to set up Firefox on a new Chromebook and running into several problems. 1) when I attempt to sync and save data, the camera option says no camera. The email option says address not found. 2) Same problem with the Firefox Help link - address not found. 3) Under the Setting menu, I don't see anything that would allow me to load in Safe mode

Thanks, David W
