Komunitné fórum Firefox

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!

My imac late 2015 running 10.12.6 Sierra crashed yesterday and on rebooting I noticed that my Firefox browser had disappeared. I was asked to reinstall with a new Extended support Release 115.34.1esr which I did but now I have lost all my bookmarks and access to my Outlook account. Is there a way that i can retrieve the lost settings?

I am unable to view my extensive bookmark list, which I have always accessed by clicking on the star button in the left margin of my screen. They suddenly disappeared yesterday.

Hello,

My Firefox app was crashing, so I turned off my computer. When I turned it on, Firefox was completely reset: no profile, app initialization... I also cannot find my profile into my files.

Could you help me please ?

For some time it has been a frequent problem with firefox not showing my bookmarks but today it has not even allowed me to restore them, when will this be fixed, I prefer not to use other browsers myself. The restore window is dead it seems.

В очередной раз пропали все мои вкладки! По непонятной причине, после очередного запуска браузера, все вкладки (около 50) не открылись - только 1 последняя! У меня в данном аккаунте был профиль КАТОК, он пропал и я не могу восстановить его и вкладки в нем. Если Вы мне не поможете я навсегда перестану пользоваться Вашим браузером, т.к. слишком часто пропадают все данные!

Yesterday, I had a trusted Firefox browser with bookmarks going back many years. Today, I have a Firefox browser which has zero bookmarks and no import capabilities. For the first time since Firefox, Edge is starting to look better.

Hi there,

I woke up this morning and opened firefox. Normally it opens the days previous tabs and this morning it didn't. When I tried 'restore recent tabs' it didn't do it. When I went into history and found the previous day's back up and tried to restore it also failed. Can you help?

Best wishes, Inez

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

Where are profiles and bookmarks and search history stored on my computer..

Maybe I can manually recover data, especially history and passwords.

Otherwise it's easier to just use Chrome

Since the last upgrade I have lost ALL bookmarks, History, everything is gone, Passwords also

I tried loading the old profile god knows what it is called, and there's still nothing

WHY DOESN'T FIREFOX BACKUP EVERYTHING BEFORE FORCING CHANGES

TURNS ME OFF USING FIREFOX.

My old laptop broke so I got a new one. I logged in to firefox, but had to change the password as I didnt remember it. Firefox said "the safed passwords might be lost" but I had to do it anyways.

Indeed the passwords are gone. Is there a way to get access to these passwords? I figure if I only could use my old laptop again, the passwords would still be there.

Thanks for the help in advance...
