Firefox Community Forum

I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Desktop Firefox 142.0.1 (aarch64) iPhone 11, iOS 18.5, Firefox 144.1 (62735)

I just reinstalled the desktop which needs the mobile phone's bookmarks. If I wipe the phone bookmarks, I lose everything. Backup, how on the phone? Sync, how? The Firefox Bookmarks Sync isn't an exact science and a misstep could be catastrophic!

Here's what I'm looking at on the desktop and the phone, attached. 1. Desktop Firefox Bookmarks Sync window show a 3 horizontal lines (hamburger icon) for iOS Firefox settings. 2. Phone Firefox has 3 horizontal dots (meatballs icon) for iOS Firefox 3. Phone Firefox has my Firefox account logged in and a Settings option, but which one (I choose Settings 4. Phone Firefox Settings shows my ACCOUNT and a Sync Now option, but which one (I don't want the phone to Sync and pull no data from the desktop and wipe the phone Bookmarks (no backups)).

I received an email from breach-alerts@mozilla.com informing me that Mozilla Monitor⁩ discovered a data breach that includes my personal information: Unfortunately, I don't know if this is a legitimate email from Mozilla. Can anyone confirm if it is or is not?

Thanks

TRYING TO FIND A SOLUTION ....

Everything failed,any ideas please? Thanks a lot

There should be a web interface to manage firefox account passwords, yet there isn't. This is seriously bad because it means the user has to install firefox to manage passwords. I installed firefox on mobile just to find out there's no option to select multiple passwords at once so i can delete all of them. Please delete all of them.

when i attempted to log into gmail today using firefox i got a screen touting their new ai stuff and requiring me to sign back into gmail. after i entered my email, it asked me to sign in with my passkey and froze. this happened three times. i restarted everything, no joy. could only enter through chrome. then about 12 hrs later i was able to enter via firefox. who knows why. i am not a computer tech person. problem is solved by the invisible hand. some tech person replied to my inquiry with the super unhelpful “i don’t have that problem.” good for you! couldn’t get back to the conversation thread to say, problem solved.

I posted a question in here two days ago because my firefox wouldnt open anymore i got a follow up answer telling me to give the crash id but never got a follow up after i sent it . i tried shuffling between profiles and in the end got it working but today my pc had a crash while firefox was open and it had to restart when i tried to open firefox its as if i just installed it and i dont have any backups to be honest i tried checking the appdata folder and there is a profile folder that seems big enough that it might be mine but it doesnt seem like firefox is reading it for some reason i tried switching the data in the profile folder that firefox is considering but it didnt work .

I changed email adress 3 month ago and didn't update my Firefox profile. With only that adress registered (no secondary email) I cannot change to a new one or add secondary because a confirmation mail are sent to my old account, that are deleted. Are there any way to change email, add phone number or .... without access to the old email account?

The Firefox icon looks like it has a shopping cart on the top-left hand side. What is this for? It is only happening on the Windows 11 taskbar (not the desktop or menu shortcut).

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"
