Diễn đàn hỗ trợ Firefox

Over the last 5 or 6 months, Firefox seems to have lost the capacity to remember my open tabs if my Mac is forced to restart. These open tabs are vital to my workflow. If this can't be solved, I shall have to migrate to another browser, which is something I do not wish to do.

My Firefox version is 147.0.4; my computer a Mac Studio 2025 M3 Ultra; my OS Tahoe 26.3.

Please advise.

Ich habe die Passwortliste bei Einstellungen aufgerufen und die war leer und alle gespeicherten Passwörter waren weg. Ich habe sie aber nicht gelöscht. Wie kann ich die Liste mit den Passwörtern wieder wieder herstellen ?

I updated Firefox last week. A few days after, I discovered that when I signed into Firefox, I couldn't find my bookmarks or extensions that I'd had on it before. I tried the "Import bookmarks" menu, but it only gave me option to import from Microsoft.

Then, I saw two firefox icons on startup menu. When I hit a faded-out one, I got into Firefox and did see my old bookmarks and extensions. When I clicked a fully colored icon, I got into Firefox but couldn't see my old bookmarks and extensions.

I saw firefox listed twice on my "uninstall" menu. I uninstalled the later one. Now, there's only the fully colored firefox icon on my startup menu, but when I click it, I still don't see my old bookmarks or extensions.

Trying to log in to my account a few minutes ago to get help, I was told the password I was using didn't work, so I came up with a new one. When I logged in after that, I got a message saying my old data might not be available.

Is there any way i can get my old bookmarks and extensions back?

I have been using the same firefox account for six years, and when the update that added user profiles came out, I successfully transferred all of my information to a profile. Well, today my firefox wasn't responding, so I used task manager to close it and restarted my computer. When I opened firefox again, it prompted me to select or create a profile to continue browsing. Crucially, it did not list the profile I had been using as an option, so I created a throwaway profile so look up what was going on and how to fix it. I tried logging into my mozilla account; no record of my previous browsing data, bookmarks, or extensions. I tried following the steps in the "Restore bookmarks, passwords and data from an old Firefox profile" article from Mozilla Support, but my old profile no longer appears in the profiles folder on my computer. I'm worried that if I keep messing around trying to restore my old data, I'll do some irreparable damage and never be able to get it back. Is there anything I can do in this situation?

since Vers. 142 I am having a really bad and wasteful time searching for my previous tabs when firefox is closed....initially it worked, but now RESTORE PREVIOUS SESSION IS NOT ON THE MENU UNDER HISTORY.... WHY IS THIS ALWAYS A PROBLEM WITH UPDATES???? IT SEEMS THAT THE UPDATES WHEN LISTED DON'T SHOW HAVING ANY TAB INFO, BUT SURE AS DAY/NITE WHEN I TURN MY DESKTOP AND FIREFOX, TABS ARE MISSING AND I CAN'T RECOVER THEM.

IT WOULD SEEM THAT IF THE DESIGNERS REALLY WANTED TO DO SOMETHING WELL, THEY SHOULD BE TRYING TO FIND OUT WHY THIS HAPPENS ON A REGULAR BASIS.

CAN'T "SNIP" A PICTURE OF MENU, SO HOW WOULD I MAKE A COPY OF IT SO YOU CAN SEE THAT RESTORE PREV. SESS. IS MISSING?

I have a machine I've been using for months and haven't got around to archiving the history and tabs for some research I was doing. I realized this could be problematic if anything happened to the machine, so I decided to sign-in to my Mozilla/Firefox account I made years ago, so it would be safely sync'd.

Everything was fine at first, it showed it was syncing and whatnot, but then after several minutes, Firefox crashed. Upon relaunching, ALL of my history is gone! Neither signed-in nor signed-out shows any history at all, except the searches I've done just now trying to undo this mess. Did I really just loose months of history due to some bug or is there a way I can manually restore or see it from the mess of cache/profile files on my machine?

Ubuntu user, so will be at ~/ or similar for most things I assume.

I have upgraded my PC from Windows 10 to Windows 11 and my Firefox bookmarks have disappeared. I understand that Firefox keeps a copy of my bookmarks which appear each time I start Firefox, so how can I make them appear again automatically when I open Firefox?

Having seen 2 versions of Firefox on my computer,i tried to delete one version and unfortunately both have gone. is it possible to recover the old version with bookmarks and passwords?

I am helping a friend who has a problem when opening any browser software on an old laptop so I cannot operate the syncing option. The old laptop uses Windows 10.

I want to transfer (to new laptop running Windows 11) the history, bookmarks and passswords by copying from users/hername/AppData/ but do not know which files need to be copied

I have installed Windows 11 to replace Windows 10 but my bookmarks in Firefox have disappeared, is there a way to retrieve my bookmarks that always appeared each time I opened Firefox?

When I tried to log in to my account earlier today, I found that it was gone. I used my recovery key to create a new password and now lost all data, passwords etc. What do I do now? Why did this happen? I am not very computer literate but have tried all of the suggestions in your help forum and nothing works. Nothing has changed on my computer since my last login yesterday. Firefox is my home page and browser.

I worked with a tech support team to update software on my computer. After the update they did a clean up on my computer today and I lost all of my firefox passwords. How can I recover these passwords?

Thanks. Bruce Tremont
