Diễn đàn hỗ trợ Firefox

Installed to new system because old system was updated to Win11 and it failed. Old system is only partially operable. Trying to copy (export and import html files) of the bookmarks to the new system, but even though the import seems to have worked, I cannot get the program to show the bookmarks correctly (or at all). They appear in the Manage Bookmarks window but will not appear on the desktop view. What am I doing wrong? When I import them, I select the All Bookmarks item to copy to but it copies everything to the Bookmarks Menu folder.

Logged onto my laptop this morning, just like every other morning. Firefox opened as if I had never used the browser before. Asked that I sent up a new profile. Could not access my existing profile. I can't find files anywhere on my computer with the information. If I open any of the old Firefox folders, I get a new set-up. Is there anyway to recover my bookmarks and passwords? Not feeling like this is a very secure product right now.

I've always had my "Open previous windows and tabs" setting on and its never failed for me but today I opened Firefox and it none of my previous windows opened, it just opened to a blank window and I've tried to recover my previous sessions but my "Recently closed windows" tab in history won't open. Not really sure what to do here as I would like to have my previous windows since I didn't bookmark them which I probably should've done

FireFox browser closed and when I opened it all my bookmarks are gone, all of my history is gone everything is gone as though I never ever used firefox in my life.

Hi, I opened Firefox to continue with my work, just to get greeted with a 'start a new profile' page. All my profiles, saved data, history, add-ons and customization, were discconected/removed. Even on my phone it logged me out from my account- logging back in doesnt retrieve my history from my previous sessions on my desktop device.

I tried logging in to my account, checking if theres an 'old firefox' folder on my device or anything like that, but it did not retrieve any of my old data.

Just to clarify, I have not played around with my settings, left or deleted anything, so I really dont understand why I've just came back to nothing.

Was wondering why this happened, how do I know this won't happen in the future, and if, when possible, how can i get all my data back?

Thanks

Today, when I opened my firefox page, I was forced to create a profile whether I wanted one or not. I did so, and lost all my established bookmarks and other links to items I frequently use. How can I recover those?

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?

RE: After a Mac re-start; despite, having the 'Startup > Open previous windows and tabs' checked in General page; the Restore Tabs option's in both the Top Menu History, and the Top Right Button Menu > History > Mange History were all greyed out. Even the keyboard shortcut to restore all Tabs > Command-Shift-T > Failed.

This has never happened before with Re-starts.

Am I able to restore all these tabs by accessing my Firefox Profile, and what are the exact steps?

Firefox 148.0 (64 bit) desktop.

Thx, Diego

Hello

After updating firefox I got logged out of firefox, after logging back in no profile data is available. I lost all the saved passwords, setting, browsing history, all of it. I lost access to website's because of it. Tried copying data from 'profiles' folder but it does not work. Never had problem like this ever and I'm considering changing browser for good. It should have never happen, like wtf is this?!

ello. My favorites have disappeared from my Windows 11 PC. It has happened once before and then I was able to get them back by deleting the sqlite file, now it doesn't work and I need your help with ending firefox processes etc.

Ich habe das Problem, dass ich in einer Anwendung in Firfox die Tasten nicht drücken konnte. Also bin ich auf reparieren gegangen. Jetzt habe ich alle meine Einstellungen verloren! Wie komme ich wieder zurück?

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?

My computer automatically restarted, and when I reopened Firefox it was updated and my account was logged out. Once I logged in, everything was gone -- bookmarks, history, extensions. The only thing not gone were my saved passwords (so I know I logged back into my same account). I swear I backed everything up after the last snafu, but now I can't find anything. How do I fix this? I had 4+ years of bookmarks saved, plus my article saver extension.

I have recently purchased a new Windows 11 computer, and want to install Firefox there and transfer all my bookmarks, passwords, etc. There are obviously quite a few Support articles on this topic, and seemingly quite a few methods to use: copy and paste profile folder, sync, the backup/restore function within Settings, etc. I'm a bit reluctant to use sync, as some users report it can be an incomplete transfer. My current profile also may contain some "corruption", so I'm reluctant to copy the entire profile folder to the new computer.

Comments by esteemed and superb contributor cor-el in this Support article: [https://support.mozilla.org/en-US/que.../1454070] therefore may be my best option. He wrote:

Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.

   bookmarks and history: places.sqlite
   favicons: favicons.sqlite
   bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
   cookies.sqlite for the Cookies
   formhistory.sqlite for saved autocomplete Form Data
   logins.json (encrypted logins) and key4.db (encryption key/primary password) for logins saved in the Password Manager
   cert9.db for certificates stored in the Certificate Manager
   persdict.dat for words added to the spell checker dictionary
   permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
   sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder) 

My questions are: 1. Why is it "best is to avoid restoring a full profile folder"? 2. Is this the complete list of "important files that are safe to restore/transfer"? 2. In my profile folder, there are several files that start with the same file name, but then have different file extensions. For example: cookies.sqlite, cookies.sqlite.bak, cookies.sqlite-shm, cookies.sqlite-wal. Should I restore ALL these files, or just "cookies.sqlite"? 3. Is the correct procedure to copy the selected files from the "old" profile, and then paste them to the "new" profile, which presumably would overwrite files of the same name in the "new" profile? Thanks!

I deleted a profile not knowing it would delete everything I had. How can I undo it? I didn't want Firefox Profiles, it was forced. I deleted it, and everything just got deleted. Can someone please help revert this? Thanks.

Yesterday, possibly related to updating to version 148, my profile completely disappaered. My old profiles are not visible under about:profiles, but are present on disk. They can not be imported with firefox -P. How do I get my profile data back?

I find that three or four times a month, the links to all my bookmarks disappear. The bookmark folders and bookmark names are still shown but there are no URLs. If I restore to a few days previously they are work again. Why?
