Hi, ok, so my computer just randomly updated my Firefox Browser and now all of my bookmarks, saved passwords, extensions, themes, and history is gone. I used the links on the support website, but they were not helpful at all. I am logged in with the same account I was originally logged in with prior to update 149.0 (logged in with gmail). When I sync data in settings, it automatically imports my Safari and Chrome information (which is not what I want). I try to import my bookmark and password history from the saved HTML and CSV files under Mozilla Firefox, but I don't have the ability to do so, as the files are essentially 'greyed' out. I have tried every step to troubleshoot and every link that is related to my issue listed on Mozilla's support with no success. I have even searched my issue on Google and Reddit. Please help!!

I am trying to recover a FireFox session from a backup of my C:\ drive from a few months ago, but I am blocked by "access denied". No matter what I have tried, access is always denied. I an using FireFox version 149.0 on Windows 10, and am trying to manually make the substitution in the folder C:\Users\...profiles\318tzbcg.default-release\sessionstore-backups.

I have tried the substitution with FireFox totally shut down (checked in Process Explorer) and even after a reboot. I am blocked from copying any of the current files to another folder or to rename them (as a precursor to (hopefully) replacing them), much less over-copying them with files from my drive backup.

I have tried from an this with CMD (run as administer) in my normal user account (which has admin privileges anyway) and with an actual Administrator account. In my User account I have verified for the properties of the Profile and sessionstore-backups folders that all of the accesses are ticked as allowed for write and read (except Special Access is not ticked). The section with the tick boxes is greyed-out (with those boxes checked), and I cannot untick any of them or put a tick on Special Access.

(I am writing this from a different machine, so have not clicked the Share Data button (troubleshooting information) on this submission form, but can provide that later from that machine,)

What can I do to get the needed access (permissions) to substitute a recovered sessionstore.jsonlz4, recovery.json4lz or previous.json4lz file?

I restarted Firefox today to find you have removed all my 100+ tabs, which I had arranged in folders, and replaced the vertical settings I had with Tree Style Tabs, which in the past has always run slow. I was greeted with childish graphics inviting me to set up a profile and offering me an introduction to Firefox. I have been using Firefox for years, mostly happily, until you screw up the view I had spent hours setting up. You are turning into a cheap Microsoft but with even less consideration for your users. Will you correct this or do I need to search for a new browser? Francis Shennan, LL.B Writer, journalist and law lecturer.

Hi. I have all the automatic opening of the last session turned on. So for the last two months, when I fired up my PC, all the tabs came back on. That is, until today!

Because I mistakenly clicked "X" when I had private browsing on in other window.

This created error that resulted in blank screen coming in... All my tabs are gone, and they are not in the recent history. How can I bring them back on"? they were just there not 10 minutes ago.

Hello, I just purchased a new desktop computer. I have passwords and bookmarks that I would like to move over to the new computer. Can this be done or do I have to manually move each item. It would be so much easier to recapture all. Thanks for you help.

My previous post seems to have disappeared, so will try again. I am 85 years old and have been using Thunderbird fo over 15 years with out any problems. Afew days ago I tried to send an e-mail and didn't have any "Send" button. In trying fix, I some how deleted my contacts sidebar. I sill have my addresses book. I have tried everything to retrieve them but no luck. I tried removing Thunderbird and reinstall, but it comes back the same. I would appreciate an guidance in trying to resolve my problem. 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.

I was browsing web pages and wanted to bring up a previously visited page, but when I went to my browser history, there was absolutely nothing. I had at least half a year's worth of history and now it's gone. How can I get that history back? For reference, I am using the latest update on a Win10 OS. I want to get this back, because there's a lot of pages I'd like to revisit but now cannot.

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?
