Firefox Support Forum

No matter what I try based on internet searches, and on this forum, I can't get my browser to save any history. After I close the closer at end of day, it erases everything. I even created a new profile.... no good. Uninstalled and re-installed.... no good. Places integrity checker says the database is sane. I checked my system care software and disabled any privacy sweeps months ago. My older (a few years back) firefox used to save everything....

Hello,

I'm a little angry right now because I have lost bookmarks of all my life and I need your help to repair it please? I don't know why but somehow, Firefox which I use for years ; (Thx by the way) ; corrupted my data on the run...? I started Firefox again but, no extension, no bookmarks, etc.. I Have kept a backup of all this FF profile, just in case.

My 1st step was to try to get a new profile a import my previous data from Firefox Sync - but somehow , I'm angry at myself again for not understanding how FF Sync work, no data from FFSync updated my data - It stayed like this for a long time , like a new profile without data (I used Xmarks before so I thought it was replacing it).

2nd step: I tried to load all bookmarks-xxx.jsonlz4 located in the bookmarkbackups folder from the FF bookmarks tools (Import / export ; etc). FF seems to see all the bookmarks but can't load them. What is really important here is that FF backed up files for like a month and even my oldest file is unusable  : bookmarks-2019-01-19-xxx.jsonlz4 !!

3rd step: I tried to get my data back from FF files, in bookmarks files like bookmarks-2019-01-19-xxx.jsonlz4 from the bookmarkbackups folder. Someone pointed me to use the https://www.jeffersonscher.com/ffu/bookbackreader.html website but all the jsonlz4 files in the bookmarkbackups folder seems corrupted (or the format of files changed and his tool may need to be updated ?)

Example : File name: bookmarks-2019-01-19_2392_mKZssqkWMZt+Mqt-HOi68A==.jsonlz4; Size: 283114; last modified 18/01/2019 à 12:38:42 (failed JSON parsing: SyntaxError: Unexpected token in JSON at position 21928) Note: To try a different file, reload this page Can't seem to acces the step 2 part even after waiting longer

4th step: tried to get old Backup of my FF Profiles with Windows 10 Shadow Copy System, "Shadow Explorer" or "System Restore Explorer" Found 3 backup wich I restored also, all bookmarks seems to get the same problem. I think I'll need to look in to this because It's not official Windows tools, but I'm really disapointed here.. I think I'll put them on md5sum tools to compare them for a start.

5th step : tried to repair my <places.sqlite> a (80MB files) which I found renamed to sqlite.corrupt. With the help of http://www.froebe.net/blog/2015/05/27/error-sqlite-database-is-malformed-solved/ , all I can get is a empty database at the end, but Im not a sqlite expert so if anyone has an idea :-)

So please, any help on this matter would be greatly appreciated.

Thank you. (and sorry for my english)

My bookmarks have vanished. This problem began when I had iTunes and Firefox open. My iTunes songs were "skipping," which had never happened before. I closed Firefox and iTunes, and I ran my Piriform CCleaner program to clear out temporary files, which I do regularly.

I ended up updating iTunes to make it work, but not before my bookmarks disappeared with the message on my browser: "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."

Worse, Firefox won't allow me to add new bookmarks.

I followed all topics in support and nothing has changed this problem. I've restarted and shut down the computer. I ran a full-system security scan. I even uninstalled and reinstalled Firefox.

Please help!

All of my saved logins are gone without a trace from all of my devices. I haven't added any new device and haven't changed sync settings recently, haven't even added any new plugins. They were all present a day or two ago and I noticed something was wrong when firefox stopped autofilling the login data. is there a way to check what's going on and what caused this? and also how to I get them back?

As above. FF installed the update despite the checked option to NOT install automatically. NO "old firefox" folder was created-anywhere. No other profile is present that has the old data. My adult daughter's grad school laptop. Years of bookmarks, logins and I do not know what all ARE GONE!! I allowed FF to download but NOT INSTALL-since it was not my machine and I wanted to avert any disaster (I, in fact, looked at the options first, to make sure) NOW WHAT?? Is that is a bug?? Why was there no "old FF" created? Why did it install regardless of instructions to the contrary. Is there some other place to look? She does not seem to have any automatic backups for FF profiles.

I opened up Firefox today and almost all my bookmarks are missing. I tried restoring, but all the backups are also missing the bookmarks. I tried exporting the bookmarks to HTML. That is not working. There is only one Firefox profile. Running in safe mode did not help.

There is a crash report from April 30, 2018. Version 60.0.1(20180516032328) was installed on May 19, 2018.

Hi!!

I had a lot of tabs open, but this morning my computer crashed, and when I restarted Firefox, I was asked wether to restaure session or to initiate a new one. I choose to restore my session, but instead of restauring my last session, Firefox restore my session as it was in early 2017, more or less 18 months ago.

is there anything I can do to retrieve that session?

I tried the solution of this thread, but it did'nt work (I don't find any sessionstore.jsonlz4 file in my profile) https://support.mozilla.org/en-US/questions/1234892 (I tried the last solution the best I can, but I'm not sure i did it properly, so maybe if someone is kind enough to help me getting through it, maybe it will do it.....)

Thanks a lot!!

After a recent update all of my passwords are gone (as well as history, bookmarks, etc)

One post says to replace the key3.db and logins.json files to restore them. However, the current folder does not contain a key3.db file. Only a key4.db file.

Hello,

my PC crashed on a windows update so had to reinstall win10. Old files were placed in windows.old.

tried to find bookmarks couldn't but did find some under favorites. However cannot see them when selecting show bookmarks! Very frustrating. Any assistance to restore my bookmarks would be appreciated. however windows.old seems to have disappeared!!

Many thanks

All my bookmarks disappeared after Firefox did an update. I have read all the articles and looked at all the solutions I can find on here and nothing seems to work. Where did they go? WHY did they go? I want them back.

For some strange reason Firefox is not logging me into my favorite websites automatically any more. I have to manually log in every time. The websites' login pages are automatically filled when I move the cursor to the Username and Password fields, but I still have to click Log In. As soon as I log out and log in I am asked to "Sign In" again. I tried manually adding a website to the "Saved Logins" but that did not help. Using Windows 10 64bit.

When using the "Restore Previous session" Firefox keeps refusing to load one of the tabs I had open last at random. Then when I copy the internet address and close the tab then use the Paste and go in my address bar, it promptly crashes that tab as well. As you can understand this is extremely annoying, so what's going on here?

I installed the most recent update a week ago, problems opening pages I had visited many times previously, too many pages, became frustrating and did a system restore to previous date then Firefox would not open at all, just kept crashing, options were to open in safe mode or refresh Firefox, tried to open in safe mode, it would not open even in safe mode so tried to refresh Firefox, got a message saying it was importing bookmarks etc but when it finally opened EVERYTHING is gone. Years of saved passwords for multiple pages, no history, no bookmarks, nothing nada...feeling pretty hopeless...HELP?

This is not the first time either!

My bookmarks are gone, my previous session is gone and I cant remember the pages I had open, my search engine that I want to add, and have always had, doesnt come up on their pages except as a theme, which I dont want... I am really really pissed that this keeps happening

I need all my stuff for my work and I have no idea what I had and its all gone...Likely 200 bookmarks for one thing and about 20 tabs

WTF! I need some help here to restore EVERYTHING I had. It was bad enough with this other add on nonsense and now this?

accidentially I deleted the history of some months ago that I wanted to keep as it slipped down while I thought I deleted just another day. How can I restore / recover / undelete the history of a Month that I want to keep? Today I deleted (20.01.2020) ist an it was I think the history (cache) of October or sth.

Would be great if someone knows help.

since after Firefox 59. All my existing passwords have gone awol (settings passwords blank) and no new passwords are being prompted to be added even if I enter them in websites. (also wierdly since 59.01 it keeps a restart message in the help even though i have updated

Every once in a while, Firefox loses my history of most-visited sites. The Most Visited folder in Bookmarks becomes empty and the thumbnails in the New Tab page return to the defaults. Any clue as to what could cause this?

FF 60.0.2 for macOS

In researching this issue from other users, I saw where you may be able to restore my bookmarks and history but you have to ask me some questions first. Please help me and ask me any questions. I am going to be very upset if all I did was refresh and I lost everything. I checked before I did it and everything was set to sync. Problem is that it's telling me that my password is incorrect but I know that it's correct. Just checked it earlier today.
