Firefox Community Forum

Hi! I reached out on Friday and was sent a code that expired in 5 minutes, missed the deadline and had to leave the library. I updated Firefox to 155 and can't find my bookmarks. Also found that a Microsoft update included Goggle Chrome that I uninstalled. Please advise on getting my bookmarks back thank you. I only have 30 minutes left on line. Thank you for all the work you volunteers are doing, greatly appreciated! Mark

Hi, I wrote about a month ago and didn't get help in recovering my lost bookmarks. I've spent the month looking at .JSONLZ4 files to see if there was anything there, nothing I could find. I've gone through all the suggestions and haven't found the bookmarks. I have limited time on line, and appreciate the volunteers' time in addressing this issue, any help you can offer is greatly appreciated. Thank you! Mark

i accidentally uninstalled Firefox and lost my session, i have Tab Session Manager but it seems that the uninstallation also deleted the saved sessions in there...

Why doesn't firefox/mozilla realize senior citizens especially ones who didn't use a computer in their line of work and taught themselves how to use a computer 20 years ago and have bought four dell computers as close to the one they had before to keep from having to learn new things. Some of us have no friends, neighbors or family to help when there is a problem..I can usually figure out how to fix issues I have had with the computer Either the last update or the one before took away the #3 profile I had and left me with no downloads, missing bookmarks and extremely anxious and depressed. My computer is my lifeline because I don't have a working car. I use it to watch YouTube TV, answer questions, order my groceries online and keep me learning about everything that's going on in this world and with my health issues. After a hospitalization three months ago my mind and memory are still not back to where they used to be and with these new updates I'm unable to get my computer back to the way it used to be. Can someone please help this old lady try to fix my lifeline?

I had a ten year well organized system of book marks. With latest upgrade they appear to be missing. All i see is gobly gook over how great the new update is, but no bookmarks.

Hello,

I recently opened Firefox and noticed that all my data (bookmarks, saved passwords, and history) is completely gone. I didn't make any changes or delete anything myself.

Could you please help me understand what happened and how I can recover my lost data?

Thank you.

Hallo Kundenservice, ich mein Betriebssytem Windows 10 Pro neu Installiert. Bevor ich das gemacht habe ich das Profil das dort unter User\AppData\Roming\Mozilla\Firefox\Profiles gespeichert warkomplett auf einen USB-Stick gespeichert. Nun habe ich Probleme dieses Profil wiederherzustellen. Ich habe zwar ein Konto bei Ihnen, und aus den ganzen Anleitungen zur Wiederherstellung von Profilen werde ich leider nicht schlau, wie ich ein gespeichertes Profil wiederherstellen kann. Können Sie mir wenn möglich eine schritt für Schrittanleitung geben wie diese Problem beheben kann? Für eine schnelle Rückmeldung wäre ich dankbar.

Mit freundlichen Grüßen

So every time the browser crashed or a blackout happens and it forced closed (sometimes the browser is closed normally and it still happens) the next time i start the browser it would show the restore session page. Pressing the restore session would just restore the open tabs and not the tab groups. Because of this i would need to go to the file manager, copy the previous.json and change it to replace the sessionstore. it's kinda annoying. is this problem just me or is this a known issue? also how to fix.

I am having an unusual problem with my main Firefox profile on Windows 10. The affected profile is:

C:\Users\Adam\AppData\Roaming\Mozilla\Firefox\Profiles\2giwv8i8.default-release-1746901618396

Firefox reports that this profile contains a user.js file. I cannot read, rename, move, modify or delete this user.js, even from an elevated Administrator CMD or PowerShell session. Attempts return “Access is denied.”

The unusual part is that Windows permissions appear correct. icacls shows my user account, SYSTEM and Administrators all have Full Control. The file is not encrypted, is not read-only, is not a reparse point, and Firefox is completely closed when I test it.

I also tested writing a new file directly into this Firefox profile directory and receive Access Denied. Other older Firefox profile directories on the same NTFS drive are writable, so the behaviour appears specific to certain Firefox profiles.

I have already performed a Firefox Refresh/reset, but the problem remains and user.js is still present.

I am investigating this because I am also experiencing unusual behaviour specifically with this main Firefox profile when using YouTube. Other Firefox profiles do not reproduce the same behaviour. I therefore want to completely eliminate any persistent profile configuration as a cause.

Can someone explain:

What could prevent access to an entire Firefox profile despite NTFS ACLs showing Full Control? Can Firefox, Firefox Sync, Enterprise Policies, an extension, or another Firefox mechanism protect or recreate user.js? Why would Firefox Refresh leave or recreate user.js? Is there an official/safe way to identify which preferences are being loaded from user.js when Windows itself refuses access to the file? Is there a way to reset all non-default preferences in this profile without losing bookmarks and saved passwords?

I can provide about:support, about:config, profiles.ini, ACL output and other diagnostics if required.

I would particularly appreciate advice on diagnosing why the profile directory itself returns Access Denied despite Full Control, rather than simply creating another profile, because I would like to identify the underlying cause.

Update downloaded a few days ago, I closed Firefox to restart with updates and I can't get my previous session back. I even tried my OneTab to see if I could get older stuff back and it's lost that too!

I have tried and tried to get my Firefox bookmarks,downloads,pictures and everything else I had on my Firefox account to no avail. Nothing I've done is bringing them back,nothing!! I even tried to get them from an old data folder and nothing was in it. Every folder and tab is gone and I don't know how to get it back as I'm 75 and not real good on technical things. Anything that anyone can do to help me would really be appreciated. Thank you, Faith

There was an electrical outage and I lost all of my settings,pictures,bookmarks,documents,home page,every thing and I can't get it back....I have tried everything I know (which isn't much) to try and get it back,like a restore,downloading Firefox again thinking that would bring everything back,but nothing I did worked...I really need to get all of that information back up and running again as I have extremely important messages and emails I just can't afford to loose. How can I get my home page back, along with all my other settings? It is so important that I get all of it back !! Can an electrical outage erase everything off of a computer and if so is it lost for good or can I get it back? Please, Help!! Thank you :)

Good evening.

I leave my windows and tabs open and turn off my computer by clicking the shut down button on Windows 10. The next day I open Firefox and all my windows and tabs come back with no problem. I've been doing this for a few years and I gathered dozens of Firefox windows and hundreds of tabs. Now that I'm finally ready to organize what I've been putting off I noticed that most of these old tabs disappeared in a very weird way. When I open Firefox it still opens all windows from these past years but it loads most older windows with a single tab and these single tabs are all in the New Tab state. I'm sure that these used to be unique tabs with content in them and not New Tabs and I'm also sure that these windows had many tabs each and not just one.

The tabs have the name "New Tab" on the tabs bar and they're gray and empty, which is what I set all my new tabs to be, so they're regular New Tabs aside from the being lighter gray than a true new tab page. Refreshing and F5 have no effect. I can't go back a page or forward because the arrows are grayed out. I can't figure out what these tabs used to be by browsing my history because they've been added to the pile sporadically over the years and are mixed with other web pages, most of which I don't want to open again, so searching for all of them would be too hard. Tab groups that only contained these "New Tab'd" tabs have also disappeared and can't be found on the tab groups list menu. If I go to "View recent browsing across windows and devices" and then "Open tabs" these tabs are shown as "New Tab" and if I click the three dots menu and select "Copy link" it copies "about:blank".

Though this is not the most specific fix, I went to Firefox>Profiles>(Profile name)>sessionstore-backups and (after making a backup) deleted all files from there except for the one with the oldest modified date. I did this with Firefox closed and then I opened it and a few of my old "New Tab" windows became real windows again with multiple tabs inside. Curiously, the recovered windows and tabs were not the most recent ones that were affected by this problem and most windows are still lost in the New Tab state.

I think Firefox has been failing to restore older parts of my session but only kind of because it still recognizes the total number of windows I had but then it opens many of them with no content (a single New Tab) and no memory (arrows grayed out).

I've always updated Firefox throughout the years and I don't know when the problem started happening, it might have started months ago and I just didn't notice because I stored the tabs and didn't look at them again until now. I also noticed that windows that were in my most recent and most used desktop instance were fine while windows in my "storage" desktops were more likely to get "new tabbed", but maybe it's unrelated to desktop environments and only related to how recent windows are and most of my newer windows are in the newest desktop, but I can't know for sure because sometimes some windows move around desktops after a PC shutdown so it's impossible to know if windows are sorted between desktops 100% by age, I think it's a Windows 10 problem. Also there have been some forceful PC shutdowns over the months due to power outages, and I have removed my drive and used a different drive with a different OS a few times, always switching with the PC turned off.

Does anyone know how to get Firefox to remember my full session and find out what these fake new tabs used to be? If not, is there a way I can restore my session to a state that it was previously like months ago? I would need something more powerful than the sessionstore-backups folder because it only helps me roll back a few weeks. I have backups from the bookmarks windows (ctrl+shift+O) but I don't think they save active open tabs. Just curious, do they save browser history? It wouldn't help me in this case as I mentioned before but it's good to know.

Thanks for your help and sorry if it's overexplained.
