Several times now I've closed firefox while having the open previous windows and tabs on startup on only for all my tabs to have been closed (with this time in particular being annoying due to losing tabs that I needed to have the specific link for). Is there any way to restore tabs lost in this way?

I'm running the current version (144.0, 64-bit) on a Dell Inspiron laptop. Just now, I tried to save a bookmark, but I found that a goodly number (not all) of my bookmark folders had disappeared. When I tried to restore from a Firefox backup, I got an "Unable to process file" message. What's wrong , how do I fix it, and how do I get the missing bookmarks back?

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

  • First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
  • Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
  • When I try searching for tags in Bookmarks Manager, the search yield no results
  • When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
  • When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?

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.

I still have not made any progress recovering my lost Firefox bookmarks. I have tried several methods with no success. The bookmark toolbar doesn't work, so I can't bookmark any more pages. I tried restarting the computer and Firefox to no avail. I am considering switching to another browser. I am using Duck Duck Go which is not as good as Firefox that I have been using for about the last 10 years. I might try Microsoft Edge or Bing or some other browser.

Sincerely

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

I am incredibly frustrated by the continuing problem of all my Bookmarks disappearing with the usual "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." This issue has been going on since NOVEMBER!!! I usually manage to get my Bookmarks back by closing all txt files that I need to keep open, store them in a new folder on my laptop, and then restart my laptop. This time, it didn't work.

Can anyone steer me to a permanent solution to this problem?

Thanks, in advance, for any help offered.

My laptop crashed and I had to format my hard and install new windows.

I have kept my passwords database files, which uses to be key3.db and key4.db along with logins.json and logins-backup.json files from my old use with me separately...

But the new Firefox folder didn't create these files anywhere where I could replace them with my files to get my stored passwords back.

Please help me restore my data from these files onto my new Firefox so I can get my stored passwords back.

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen
