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.

Help! All of my bookmarks, browsing history, and profile prior to Sept 4, 2026 have been erased. Firefox instructions for restoring these prior bookmarks do not work. When I access "manage bookmarks" then the "Library", then "import & backup & restore", there is nothing listed prior to Sept 4, 2026. So there is no file to choose. Also my prior profile has been erased. My profile is completely blank altho I did NOT create a new profile nor did I access my profile in any way!!!

Also the instructions for "restore bookmarks from backup" do not work either. I desperately need that browsing history and those bookmarks. I am doing research for an art history project & those bookmarks for the last two years were stored there & seemed securely in place for the last three years. I need those bookmarks & the browsing history which included sites I used but did not necessarily cite in my research.

My bookmarks included the sole documentation I had of my research for this project for the last two years!!! When Firefox said it would continue to support Windows 10, I had no reason to believe my entire browsing history and/or my previously secure bookmarks would be erased. Help me restore those bookmarks. dona bretherick

Help! My bookmarks tool bar is missing & I cant recover it because your instructions for locating the menu bar don't match what your instructions display. There is NO AltGr displays a bookmark menu BUT I CANT MOVE IT TO MY TOOL BAR. There is NO selected tab, NO menu bar; NO bookmark tool displayed. I have also lost all of my downloads. This has happened in the last month; everything was fine. I am 82 years old & NOT a techie so expect better help than I have received so far during the last frustrating 2 hours of trying to follow Firefox instructions that DO NOT APPLY TO ME. Also the "add images" function @ bottom of this page won't let me send you a copy of the instructions you display to select the bookmark menu bar ... I click on the picture of the problem & nothing happens ... just dead no access to select pictures either.

I have NOT changed my internet provider; I have not changed any settings. This all happened two weeks ago. Called internet provider & they said it was Firefox issue!!! Very unhappy.

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

Why cant I access "ask a question" anymore as no link appears. How do I contact someone as the community has locked the thread concerning lost bookmarks. I need those bookmarks back!

I started a new conversation because all of my bookmarks have disappeared. I have five years of important bookmarks which I assumed would be kept in bookmarks. Now only the one bookmark I made today is available. Also Alt and AltGr does not link to anything. This happened in the last month. Also the "add images" link on this link is not functional anymore; I cannot select a picture either. I have Windows 10 and my system lacks the capability to upgrade to Windows 11 even if want to. Firefox says it will continue to support Windows 10 but something must have changed in the last several weeks. dona bretherick
