Firefox Community Forum

The entire browser was acting extremely slowly, on every website, every start up. It crashed constantly to the point it was unusuable, it was even affecting the performance of the rest of my pc so I reset it and everything I had on the browser disappeared. Bookmarks, passwords, etc. I've tried going through the profile support pages but only the profile made from the reset exists. I had years worth of important bookmarks and passwords that'd I'd like to be able to get back if that's at all possible. (I'll live without them, it'll just suck trying to remember them all again) PC is Acer Aspire 3 Spin 14, Windows 10

I am changing from Win 11 to Linux Mint and want to use as much of my Win Ff profile there... What can I trnansfert, and how, where will I find Ff extensions for Linux?

Thank you

Before reinstalling Windows, I made a backup, but since I didn't update the system until a day later due to work, I forgot the backup password. I've tried every password I could think of, and I don't know what to do now.

With the new Firefox updates I no longer see my bookmarks. I tried the FAQ's and suggestions but I don't understand them. I need my bookmarks back ASAP! Tried ctrl-shift-B it did nothing.

I lost all my data after installation of new firefox. I have lots of important data in that profile.

I forgot the password to sign in and when I reset, a new profile was created for me and all my data are gone.

Now, I even know the original password. I did not know, I will lose my data. How can I get my data back? Please help.

Windows 11 Firefox crashed on opening continuously so unable to safe open etc. Did update intel graphics to no avail. Uninstalled in add programs in settings. Did not choose to delete data. Reinstalled and now can't find my profile.

I AM HAVING THE SAME PROBLEM AGAIN, I HATE HAVING EVERY SINGLE ONE OF MY TABS DISAPPEAR WHENEVER IT CLOSES WEIRDLY AND I LITERALLY CANT RECOVER ANYTHING, AND IT GIVES ME SOMETHING NEW, WHAT THE HELL EVEN IS THIS FIRST FILE, I HAVE NEVER GOTTEN THAT JSONLZ4 FILE E V E R!!! AND WHEN I TRIED TO DO THE SAME METHOD OF REPLACING THE FILES WITH ONE OF THE OLD RECOVERY FILES LIKE IN MY OLD QUESTION, IT DOESNT FUCKING WORK, SORRY TO SWEAR BUT ITS UTTERLY RIDICULOUS DUDE!!!

Firefox crashed and now my shortcuts have gone and the bookmarks are not easily accessible. I tried importing from the desktop but they are now in a long list and not as they were (in the toolbar. I can't gt the "bookmark summary" showing in the toolbar area.

While launching Firefox VPN browser all of my bookmarks were erased. Additionally, my backup copy of my bookmark records was also deleted. I have not been able to reboot or restore the system. I need help.

I deleted my history and it also deleted all my information. I cannot sign into any thing because it is not sending the code to my phone. Even on other browser I cannot get any infomation because the code is not being sent go my phone and I cannot use my email because I cannot get a code to open it. Please Help.

Zniknęły mi zakładki (nie ma ich ani na pasku, ani jak wejdę w zakładki- w ustawieniach i w zarządzaniu zakładkami). Hasła te co były zapisane mam dostępne na moim koncie.

Basically, I reinstalled Windows, and I had all my passwords and stuff on my Firefox beforehand. Now, I don't remember my accounts password, and not the security key either.

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!
