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 have duplicated my current ff profile which has sync enabled. I have created a new ff profile which uses the copied directory as it's root directory. Opened a new browser window with the new profile and then started to cleanup/delete some bookmarks and add-ons and noticed that all bookmarks started to disappear from the source ff profile.

I don't have any backups of any kind. Just Firefox Sync enabled.

Q: Can you help me recover my bookmarks from a specific point in time (21st of March)?

Thank you! \m/

on MACOS 10.12.6: after launching Firefox browser and auto-update, there was a warning in red bar at the top regarding functional issue with history and bookmarks. Both history and bookmarks now disabled. Bookmark tool was selected to restore from the most recent backup in the list, but upon executing that tool, received the error msg: 'unable to process the backup file'. Also, now, History > Show All History = nothing

Hi my browser updated last night and all my bookmarks AND browsing history are just gone from the regular Firefox (i also have the dev edition installed)

All im left with now is an "Old Firefox Data" folder on the desktop and it contains data from the dev browser, where is the data from the non-dev browser ?

I did not have a user signed-in on either of the browsers

When I receive an update for FireFox, when it is "allowed" all my data in Microsoft Money is deleted. How can I prevent this? It's a nuisance to be repeatedly re-entering all the data every time there's an update.

I'm using genuine windows 10. After a recent update (Feature update to Windows 10, version 1809), my firefox (updated) address bar HISTORY & all the BOOKMARKS have disappeared. I'm unable to restore it. When I try to bookmark any site, it does not do it. Plz let me know the step by step procedure to resolve these issues. Thanks in anticipation.

Hi! There is a bug. YouTube History is not saved when i use Firefox as browser. So I deleted it and then reinstalled it, logged in to it and played videos from YouTube again. Then i checked again the history and saw that it was saving. Later without any changes in Firefox settings (including addons), the problem began starting again. I still don't understand why it is happening. The addons that i have installed are: Kaspersky Protection, Malwarebytes, uBlock Origin and Privacy Pass. This problem doesn't happen when i use Chrome Browser with same extensions.

I am unable to follow the directions to try to restore it because they start by telling me to click a Library icon (which I cannot find).

Instructions: Manual backup

   1. Click the Library button 57 library icon , then click Bookmarks. (I don't see this Library icon anywhere.)
   2.Scroll to the bottom and click Show all Bookmarks.
   3. In the Library window, click the e3f62ffc25d52f883aa490cc65d71e2d-1252097598-804-1.png Import and Backup button and then select Backup.... (no Library window, hence no Import and Backup button)

Please help me — thank you!

When I update my Mac to Mohave, all my bookmarks in Firefox vanished. When I try to install them from the backup, it just says it cannot read the backup file. Help! please! I really need these back.

Tried to opened Firefox this morning. Immediately received message box that "Firefox was updating, please wait". When Firefox window opened I did not see my Homepage. Instead there was a window asking me to launch POCKET via Firefox, GOOGLE or email. I was surprised because I had no idea what "POCKET" was. I clicked email but the next screen gave me no more information about what POCKET was so I backed out and opened another window with my HOMEPAGE. When I next clicked BOOKMARKS I discovered my BOOKMARKS folders were all empty----- no bookmark links at all. I tried "Restore Firefox" - (nothing) and then "Restore Bookmarks" ( also nothing.) I am devastated...... Please Help

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?

It instructed me to reload firefox, or something to that effect. It told me I would NOT lose my bookmarks. It lied, I lost all my bookmarks!!!!

Now I am trying to recover them, but I am a 76 year old 'non geek' who has trouble understanding all this new tech language, and following this often confusing road map to correct these problems. Sometimes I as myself, 'why don't you guys leave well-enough alone' ?

Please help me get my computer operating correctly again so I can go back to my multiple forum activities,...and get my model railroad and sailboat design activities done

I inadvertently deleted the preferences folder, browser.places, and now I have no Most Visited folder. The procedure offered for Firefox 62 does not work with my Firefox 64. I have created a new profile. I have deleted and reinstalled Firefox, but it is still missing.

I have had this problem for a few months now and eventually just stopped using Firefox. I had tried the various suggested fixes to no avail. - rebooted - tried running in safe mode with no antivirus programs - renamed the places.sqlite file - I deleted Firefox, downloaded and installed it again with no success. I am concerned that not everything was removed on the Windows 10 uninstall process. - Have checked my Antivirus (Bit defender) logs and don't see any Firefox files locked/etc by Bitdefender

I would appreciate any suggestions that you might have. Regards Bill

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.

Hi, A few hours ago I cleared the last hour of recent history, FYI I checked browsing & download history, form & search history and cache when doing it but after that I realised all my closed windows and tabs were lost except the ones being opened.

In the session backup folder there is only 2 files, recovery.baklz4 and recovery.jsonlz4. Actually I just checked, there is 3 now, previous.jsonlz4, but they're all pretty much the same, after I lost those windows and tabs, and the former two seem to be constantly saving themselves, not sure why, is this supposed to be happening?

Usually there were upgrade backup files such as [upgrade.jsonlz4-date] but I don't have them in [sessionstore-backups], has something changed or is there something wrong with my browser?

When I realised my closed windows were gone I immediately made a backup but it was too late, they were all after I've lost the closed tabs and windows, and there were only two files (the files constantly saving I mentioned earlier).

So how should I proceed? I want to get my session restored but the last usable session backup I've made was months ago.

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.
