Hi. I accidentally deleted the "Today" subfolder that exists under the "History" section in Mozilla. How can I get it back? I'm not interested in getting the internet history from today back, just the folder. Thank you for your help.

Не знаю по какой причине, возможно какой-то баг или ещё чего, но у меня пропали все вкладки, даже те, которые были сгруппированы. Возможности восстановления предыдущего сеанса у меня нет.

Since yesterday, I suddenly had to recreate my Firefox account, which I have used for a long time. For no apparent reason, my email was not recognized as an existing account when I tried to synchronize my browser. As a result, I created a new account using the same email address. Consequently, all my email masks have disappeared from relay.firefox.com. Is there any way to recover those masks?

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?

Hello! I accidentally logged into my account after switching to a new computer, creating a new recovery key. Now i do not have access to all my saved passwords. I have my recovery key but cannot find where should I type it to get back all my information. Is it possible to recover my information using the original recovery key, not the one I accidentally created? I really need to get the access to all my saved passwords, please help me with it. Thank you!

I have been a Firefox user for many, many years. I started getting the Subject message: "The bookmarks and history system will not be functional" error message this evening. I started to "Fix" this error based on the Mozilla Support page. Actually, I first tried restarting my computer and that didn't correct the problem. I then noticed I could "sign off" Firefox which I thought I'd do and sign back in. I didn't notice until after the fact that my Firefox account was tied to a very old email address I once used that is no longer active "commish3@bellsouth.net". When I tried signing back into Firefox using that old email account, it said a security code would be sent to that old email address. Problem is I no longer have access to that email account.

1) Is there a way I can sign back in and have a security code sent to my current email address: tad3.dickinson@gmail.com ?

2) Can you assist with restoring my bookmarks. Again, years of building these bookmarks that I'm very dependent on.

Thanks, Tad Dickinson

I'm setting up a new computer, (Windows 11). Currently on a home WIFI network, in UTAH, with another computer, (windows 10). Very soon the new computer will be moving to my retirement home, in Nevada, on a new WIFI network.

Basically, How can I import Firefox bookmarks from another computer that is on the same WIFI network?

My bookmarks have stopped working. When I went to Edit Bookmark I found they are all empty. I can create a new bookmark as usual, but I have over 300 bookmarks that no long function that are very important to my work. Is there any way I can possibly restore them, as my work depends on them?

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

Rebuilt my computer, restored Bookmarks from 'bookmarks-2025-08-30.html' but the original 'Other bookmarks' (just below 'Bookmarks toolbar') is now empty and has been moved to the bottom of all my other bookmarks in a new 'Other Bookmarks' folder. How do I get the contents back in the 'Other bookmarks' (just below 'Bookmarks toolbar'). P.S. I have a backed up 'bookmarks-2025-08-30.json' as well as a ' bookmarks-2025-08-30.html' available, if that would help. Regards and Best, NP_145

I would like to know what happened to all of my bookmarks I had when I opened my firefox, nothing is there and I can't seem to find out how to restore them.. what ever you have done to firefox, mozilla I hate to say I don't like it at all.. thanks

I had a lot of tabs open in Firefox, and they always stayed there even after restarting my PC. But suddenly, all of my tabs disappeared, and I can’t recover them using “Recently Closed Tabs.” Can I get them back?

Using firefox 144 on Kubuntu 24 LTS, on wayland, with Nvidia drivers.

I'm one of those guys with 500+ tabs. I also have a bunch of tabs open in specific containers and I recently spent a lot of time sorting most of my hundreds of tabs into a bunch of neat tab groups.

I'm not using any "sync between devices" functionnality

At some point, I open firefox like usual, and I noticed that it appears to be glitched. The rightmost tab (the last tab I had opened) seems to be working fine, but every other tab has no text, and I cannot switch to them. However, the colored line indicating that a tab is opened in a specific container still appears, it's just the tabs names that are missing. Also, firefox seems to generally not be responding, so I decide to close and reopen it.

Upon reopening, firefox restores my tabs, but I'm left with only the last tab I mentionned earlier. The "restore last session" button doesn't appear in "history". Neither "recently closed windows" nor "recently closed tabs" contain my 500+ tabs

I still have my extensions

I still have my bookmarks

I still have my base "new tab" setup, with my background image and my "pinned" websites (I don't know how it's called)

I still have my container "rules" (i.e, firefox still proposes to open specific domains with specific containers, even if I have lost old tabs that were opened in those containers)

I still have my "auto sign-ins" (i.e, I can still log into some websites without re-typing my password)

I have lost my tab groups

I'm used to losing my tabs. So I close firefox, and I go look in it's files.

The image firefox-mpris in the files still displays a youtube tab I was watching (yet this tab doesn't get restored)

I make a copy of sessionstore.jsonlz4 and sessionstore-backup, and try restoring from each backup by replacing sessionstore.jsonlz4 :

- the default sessionstore.jsonlz4 doesn't have my tabs of course

- previous.jsonlz4 has only the single last tab I mentionned earlier.

- recovery.jsonlz4 contains only 20-ish of some of the most recent tabs I had

- the "upgrade" files contains a bunch of tabs but it's from a few months ago so I'm missing the most recent stuff

Using this "scrounger" tool, I can look at what these files contain

https://www.jeffersonscher.com/ffu/scrounger.html

- sessionstore.jsonlz4 and previous.jsonlz4 both contain the single tab we talked about before (plus closed windows I don't care about)

- recovery.jsonlz4 contains exactly 25 recently opened tabs (plus closed windows I don't care about)

- upgrade.jsonlz4 contains 500+ tabs (with container ids, yay), but not the most recent ones of course (plus closed windows I don't care about)

From I saw online it looks like firefox only stores the last 25 tabs in these files, which are the last tabs I actually opened, even if more actually exist. What I really don't understand is : - Why does my upgrade.jsonlz4 file have more than 25 tabs then ? - Where are the other tabs supposed to be stored then ? the .jsonlz4 stores the last 25 tabs, yet firefox (usually) remembers all my 500+ tabs anyway, so where are they stored ?

Also, y'know, pls help me restore my stuff. Thanks.

cleaning up my computer, I accidentally deleted firefox. I had a list of favourite links, and I lost them. Is there any way of recovering my list of favourites?

thank you, Glen A Goodale, [email removed]@gmail.com

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

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.
