I-Firefox Community Forum

FireFox browser closed and when I opened it all my bookmarks are gone, all of my history is gone everything is gone as though I never ever used firefox in my life.

So far hate new Firefox that I have been forced to switch to - very annoying and such a waste of my time trying to sort out my bookmarks. May make me switch to Edge or something.

Followed the instructions - C:\Users\name\AppData\Roaming\Mozilla\Firefox\Profiles\ - found a backup but no information as to how to get the bookmarks into the new Firefox?????

Many of us are older users and perhaps not so savvy as to how to do this.

And so it would have been nice if Firefox could have been more "nice and be specific" with this forced change over.

Thank you

Hi, I'm Albert.

I had like 10,000 open tabs (not exaggerating) and these tabs are gone after a blue screen error and a few Windows updates. I want to restore those tabs, but I can not because the "Restore the previous session" option is grayed out.

Are there ways to restore these open tabs?

If there isn't one, then I want to restore all the websites I have visited over the past few years and manually filter them.

How do I do it?

The Firefox library contains history but the oldest history it contains is 2024 December one. I guess the dedicated folder removed my old browsing history as it was filled up?

What I read is that places.sqlite file contains all the browsing history. Is this right? My places.sqlite file size is 80.0 MB (83,886,080 bytes). Is there a size limit on this file? I wonder if this file contains all my browsing history.

I have my places.sqlite file and DB Browser installed on my computer. But I don't know what to do next after opening places.sqlite file.

If there are better suited applications for my purpose than DB Browser, please recommend me one with a little instruction.

Long story short, how do I restore my open tabs or browsing history?

Please help me.

Mozilla usually doesn’t restore all the windows I’m working in; when I open it, it only restores a few of them. I usually use the ‘History’ > ‘Recently Closed’ > ‘Reopen All Windows’ option, but this time not all the windows I need are being restored. My most important window, containing 1,000 essential tabs for various articles, hasn’t been restored, and it seems as though I have absolutely no chance of finding it at all; I don’t even have a ‘Restore previous sessions’ button. I don’t know how to get that window back, because restoring the tabs one by one would take an age and I’d probably lose a lot of them (it’s very important that these were tabs, not bookmarks). What should I do?

Hello and good afternoon. I have a problem with my last session as it doesn't appear, even when I try to do it manually in Settings-History-Import and backup-Restore, it shows me some options of different dates with all my last browser history, but none of them works, it simply doesn't open any of the web pages. I don't have any other profile, and I already tried the troubleshooting too I Hope you can help me. Thanks in advance

I read the existing articles and followed them, starting with "manage bookmarks". When I click on restore, there is a list of the last 15 backups by date. EVERY one of them results in an error message "unable to process the file".

Manually searching for bookmarks.html or json, resulted in nothing found at first. Then I discovered the path to the bookmarks folder were all hidden folders (after the 'user' folder). I got them to display in file explorer ('show hidden files' selected) and tried to manually select the JSON files that way, to restore bookmarks. That also did not work, resulting in the same message depicted below.

Please help

My bookmarks have stopped working. When I went to Edit Bookmark I found they are all empty. I can create a new bookmark as usual, but I have over 300 bookmarks that no long function that are very important to my work. Is there any way I can possibly restore them, as my work depends on them?

Last night I had an operating system update. Before the OS update, I closed all open apps, including Firefox. In the past, the session I closed the previous evening was restored. But this morning, all my pinned tabs and other open tabs are gone, and Restore Previous Session does not appear as an option on the dropdown menu. Recently Closed Tabs is pretty random, not really helpful. Recently Closed Windows only shows one tab that I opened this morning (probably a mistake on my part). Is there any way for me to retrieve the session from yesterday?

Three days ago a window popped up asking me to update Firefox. I did and afterwards my personal bookmarks listing disappeared. I tried rebooting everything. No luck. I went to your website and followed all of your suggestions, but again nothing worked; mainly because I could not find on my computer the info the last step in your suggestions were asking for. (I did get a message several times telling me I was using an old Firefox profile. I tried to investigate, but each time your instructions told me to look for something as the last or next-to-last step, I ended not being able to find it on my computer. Again, I have tried everything. Please help me.

I am helping a friend who has a problem when opening any browser software on an old laptop so I cannot operate the syncing option. The old laptop uses Windows 10.

I want to transfer (to new laptop running Windows 11) the history, bookmarks and passswords by copying from users/hername/AppData/ but do not know which files need to be copied

When I tried to log in to my account earlier today, I found that it was gone. I used my recovery key to create a new password and now lost all data, passwords etc. What do I do now? Why did this happen? I am not very computer literate but have tried all of the suggestions in your help forum and nothing works. Nothing has changed on my computer since my last login yesterday. Firefox is my home page and browser.

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

I posted a question in here two days ago because my firefox wouldnt open anymore i got a follow up answer telling me to give the crash id but never got a follow up after i sent it . i tried shuffling between profiles and in the end got it working but today my pc had a crash while firefox was open and it had to restart when i tried to open firefox its as if i just installed it and i dont have any backups to be honest i tried checking the appdata folder and there is a profile folder that seems big enough that it might be mine but it doesnt seem like firefox is reading it for some reason i tried switching the data in the profile folder that firefox is considering but it didnt work .
