After restarting my computer, I got a new FF web page and ALL my bookmarks as well as history have been deleted.

How do I get them ALL back?

I have tried every solution on the Mozilla Help section - I cant do a Restore I have a very old version of backups - 2016

The online help system is going around and around in circles not giving any solutions. 4 hours of trying to sort this out is ridculous.

I really do not want to have to move to Chrome, I far prefer Mozilla, but I can not afford to loose more time sorting this problem out. If not resolved here, I will reluctantly have to restart all my bookmarks in Chrome.

I need all my bookmarks - some are work related.

Please Help

i have lost everything and struggling to get all my bookmarks back after a update from firefox- HELP! Is there a number where someone can talk me through this as I cant seem to sort it from the support pages

Hello, my problem is as follows:

I had a session open when i updated Firefox. It closed the browser however Firefox didn't show me any indication that it was updating so i tried open it again. Right that moment the update window showed up and somehow Firefox crashed. When i opened it again, my previous session was lost and i have no way of retrieving it. There is no option popping up in the menu that says 'Restore Session' and other methods that i have seen online are a bit difficult to understand.

Also the sessions i can recover are all after Firefox kinda crashed/Firefox updated so i don't know how to get my old session back. The session i want to recover is before i updated to Firefox 62.0 on the 10th, September. (Time stamp would be around 5:30pm CEST)

Oh and i have seen this thread (https://support.mozilla.org/en-US/questions/1204253) and i tried doing it, but the session i want back is not there.... does that mean worst case scenario happened and i won't be able to get my session back? ;____;

This may be a dumb question but would reseting my windows version to 9th, September help? I mean it would erase the update i did for Firefox and should (as much as i know <.<) also reset the setting for Firefox to yesterday's ones correct? But would that help since my problem is on the net surface and not a computer problem >.>

ps: i wanted to upload pictures but it somehow doesn't let me, so if you need them, please tell me and i will try to send them.

Please help me!! I’m desperate!! I have 15 years of saved passwords that no longer work!!!!!!! After I updated to 73.0 I have zero saved logins!!! My logins.json file is still there and I can open it in Notepad but everything is encrypted!!! Also, it says I don’t have a Master Password anymore, but I never cleared it! And when I go to change it I get a “unable to change” error!!! I also can’t save any new logins, no logins can be saved now!! I’ve searched google for hours and tried everything but nothing works!! And no, I don’t have the “logins.json.corrupted” file everyone mentions on other threads for this issue, my file is still logins.json!

Please help me!!!!!!

I never had a firefox account till now. So, I had to reset the pc where i had all my logins. I once had to export my passwords (exporting key4 and logins.json files) and it worked, so i didn't think to much about it. So i reset the pc without cheking if the passwords actually worked (yuh, my bad). The problem is that apparently mozilla doesn't recognize the files, or something, cause when i open "Logins and passwords" it's empty. I don't know what to do, please help me.

All my Bookmarks and Tabs have vanished after the Firefox 82.0.3 update yesterday. Related? Searching for hours, including Firefox site and cannot find solution. I noticed 'Restore Previous Session' was recommended as a 'fix' at some links. Mine is grayed out...if that matters. I have VERY important bookmarks, including links related to Hurricane Sally destruction to my home. PLEASE HELP! I'm not very computer savvy, so 'instructions for dummies' would be helpful. PS...I was able to bookmark this page, but at least 100 bookmarks vanished. Tabs & Bookmarks are fine with Safari and Chrome. Unfortunately, I rarely used those and did not migrate most Bookmarks to them. Lesson learned. Thanks in advance John

Firefox is set for automatic updates. I have no issues with my anti-virus program. After Firefox update 62, all of my user IDs and passwords are gone. I have tried restoring everything via my pc (windows 8.1). I have tried restoring Firefox. The saved passwords and User names are gone. Is there a way to restore them, or do I need to rebuild the list....one at a time?

Greetings,

I have been unable to restore my previous bookmarks due to the recent Firefox update.

I have tried to ctrl+shift+B and try to import my bookmark in the backup file in my profile folder but whenever I try to import my bookmark from the backup folder it says "unable to process backup files".

Ive also tried to import them from html link using the link I got here ; https://www.jeffersonscher.com/ffu/bookbackreader.html , it doesnt work, tells me the download "failed"..

I also tried to change the file extension from .jsonlz4 to .json ,still not working...(unable to process file).

Please help me get my bookmarks back, this is so frustrating.. Also needless to say im totally clueless in terms of computers (I am 62 years old),It took me 2 hours to understand and try to follow the instructions in similar post, Im not even joking... could you please use simple language and instructions in order to help ?

Thank you.

Something happened and all my bookmarks are gone and the old Firefox data folder on my desktop was deleted by accident. I have looked everywhere and done system restores. How do I get them back? Does Firefox support offer screen sharing support?

Going from ESR to regular firefox bookmarks and saved passwords are gone. Import does'nt have an option to import from ESR version. How do I get my bookmarks and saved passwords back?

Today for no reason all my saved passwords on my desktop Firefox browser have disappeared. Fortunately on my android phone they all still exist. I have tried to sync and on Android it confirms sync has happened but the passwords will still not show on the desktop browser. Only new passwords now entered are being recorded.

I have never had this problem ever and have done nothing today that would cause this to happen

I have the most recent FF 66 and up to date Windows 10

Any suggestions welcome please.

Basically i noticed that whenever i installed adblock or any other addons they don't show up in the top right bar as icon and even if i have them enabled they do not work, i searched a bit and it seems to be an old issue that was present with some older version of firefox, is somebody currently experiecing this?

Hello FF team.

starting with FF update 56 to 57 and so on I got this strange problem: it looks like my key4.db file gets corrupted and FF become almost useless after I access my saved passwords and then exit the browser. If I delete the key4.db file (I still have the key3.db and logins.json files in profile folder) everything works fine. The key4.db file is generated, my passwords are there and I can use them till next browser exit/restart. Here are the symptoms:

- upon start the browser directly asks for master password (normally I'm asked for the master password only when I really need it) - no browsing history is shown in the address bar - enter key and 'Go to...' button do not work at all (I can only open a site if it is bookmarked) - when I go to browser's options there is nothing under 'Search' section - in other words the content cannot be loaded or displayed - when I open 'Saved Logins' dialog there is nothing - there are no *corrupt files in my profile directory

So when this happens I have to exit the browser and delete the key4.db file. However if I don't access my saved logins during the session at all, there is no such problem. I can start/use/exit the browser as many times as I want and it works fine. So it looks like the access to the saved logins breaks something.

Suddenly today when I opened Firefox, the Top Sites section on my new tab page had only blank icons. I previously had several pinned sites. I'm also unable to manually add any top sites. If I try to add a new top site, and enter a name and URL, when I click the "Add" button, nothing happens. No new site is added. I have uninstalled, rebooted, and reinstalled Firefox several times with no success. I also went into about:Config and saw that for the item browser.newtabpage.pinned, the value contains all the URLs for my pinned sites. They're just not appearing on my new tab page and I'm no longer able to manually add any top sites. Also, none of the sites I visit now show up, they're all just blank icons. I'm using Firefox version 62.0.

Hello! I've got a problem since a week in Firefox, all my sessions and settings on websites are not saved.

For exemple, when I want to use YouTube, I first get connected, then I turn on the dark mode. Until I close Firefox, it will save those settings, even in new tabs. But if I close and reopen Firefox, those settings are gone. I need to connect again on Youtube, and dark mode is no more activated.

Same issue on all websites except for those which were saved before the first time I saw the problem. But if I close my sessions on them, then it will be the same.

I tried to completely remove (program and userdata) Firefox and install it again, still the same. I tried to clear the cache, still the same. And I tried to reinitialize Firefox with its own function, still the same.

So I'm wondering if someone would help, because Firefox is my favorite browser and I can't get used to another.

Thanks, Tun.

PS : My english may be weird, I'm sorry for that.

I had a system crash, probably with Firefox opened.

After restarting PC and starting Firefox, most of the addons I have had lost all of their settings and were reset to default - Tampermonkey lost all the scripts I had installed, uBlock lost all settings and rules, etc. Weirdly some extensions kept portions of their settings, like TreeTabs saved tree structure despite also getting reset to default.

Additionally Firefox also got its own settings reset to default, while the tabs from my session and bookmarks were saved.

Is there any way to recover addon and Firefox settings, is there any backup of them?

I checked the only other response that I see (about:preferences#security), which I cannot enter as a URL.

I lost all of my logins/passwords tonight, after reinstalling v 66.0.2. I created a couple of passwords, including here. They are NOT in my saved logins. That has never happened before.

I always save logins. And I always update my logins when I change them.

This is becoming tedious.

Thank you.

A couple of Firefox updates ago, I lost everything I had saved in OneTab. I didn't export or otherwise save partly because they had always been there after the update. Is there any way to recover them? (probably 100+)
