Firefox 커뮤니티 포럼

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?

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!

Hi, I'm Albert.

I had like 10,000 open tabs (not exaggerating) and these tabs are gone after a blue screen error and a few Windows updates. I want to restore those tabs, but I can not because the "Restore the previous session" option is grayed out.

Are there ways to restore these open tabs?

If there isn't one, then I want to restore all the websites I have visited over the past few years and manually filter them.

How do I do it?

The Firefox library contains history but the oldest history it contains is 2024 December one. I guess the dedicated folder removed my old browsing history as it was filled up?

What I read is that places.sqlite file contains all the browsing history. Is this right? My places.sqlite file size is 80.0 MB (83,886,080 bytes). Is there a size limit on this file? I wonder if this file contains all my browsing history.

I have my places.sqlite file and DB Browser installed on my computer. But I don't know what to do next after opening places.sqlite file.

If there are better suited applications for my purpose than DB Browser, please recommend me one with a little instruction.

Long story short, how do I restore my open tabs or browsing history?

Please help me.

My computer shut down. I turned it back on, and the browser was completely updated. Nothing! I'm panicking. There's not a single backup anywhere. there is no folder on the desktop «Old Firefox Data» I don't know what to do I tried to restore bookmarks, but the list only showed other browsers.

Mozilla usually doesn’t restore all the windows I’m working in; when I open it, it only restores a few of them. I usually use the ‘History’ > ‘Recently Closed’ > ‘Reopen All Windows’ option, but this time not all the windows I need are being restored. My most important window, containing 1,000 essential tabs for various articles, hasn’t been restored, and it seems as though I have absolutely no chance of finding it at all; I don’t even have a ‘Restore previous sessions’ button. I don’t know how to get that window back, because restoring the tabs one by one would take an age and I’d probably lose a lot of them (it’s very important that these were tabs, not bookmarks). What should I do?

Ok, so I dont use my computer that much, but anyway. I get on it today and this "create a profile" pops up. once I get in to firefox Everything is gone, my history, passwords, bookmarks, addons.

WTF happened???????

I hard shut down my laptop and when I re-opened it, Firefox seemed to have reset itself completely. My profiles were gone, my bookmarks are still present but their icons are missing, my background is missing, my extensions un-pinned, and -- naturally -- all of my tabs were closed. My original profile is completely gone, which kind of sucks, because it was pretty personalized. I think even my preference settings reversed themselves, because it tried to show me the AI chatbot on the sidebar, which I had turned off. I figured at first that it was a matter of spotty connection, because I was using my phone's hotspot at the time, but I'm now back with a solid wi-fi connection, and everything is still acting strangely. Help? How do I get my original profile back in its proper form, if possible? Or, at least, the icons to show back up on my bookmarks? I have turned everything off and back on again, as it were.

I tried everything I could find and still no luck. Read firefox stores 15 prior session setting to restore from and they are nowhere to be found. I'm at a lose on how to move forward. First firefox did it and was able to recover a couple of weeks ago, now windows update did it!

Please Help, James Johnson

Thank You

Hello and good afternoon. I have a problem with my last session as it doesn't appear, even when I try to do it manually in Settings-History-Import and backup-Restore, it shows me some options of different dates with all my last browser history, but none of them works, it simply doesn't open any of the web pages. I don't have any other profile, and I already tried the troubleshooting too I Hope you can help me. Thanks in advance

I keep losing all my saved passwords in my Firefox browser when I get a Windows 11 update, Why and how do I recover them and prevent them from being deleted when there is Windows 11 update? thank You

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.
