suspected sessionstore.jsonlz4 corruption possible Sync rollback conflicts extremely large tab sessions spontaneous restoration of previously closed tabs during live browsing I am not a techy person. Have seen on Chat steps that can be taken, but it is too complicated for me. Seeking remote or other help. Would like to know how complex an issue this is. I'm having a very tough time. It just restored around 1,000 previously closed tabs. It takes me hours to close them because they get mixed up with the tabs presently opened. It interferes terribly with my work. I'm reaching out to IT companies and then found you through Chat GPT. Please help if possible. TY! This is a Lenovo t16 laptop with windows 11 for home or personal. I haven't had a tuneup for a long time. I read that's not a good thing to do with this issue.

My system was hacked and I had to factory restore it. I didn't write down my login/passwords because I was informed that as long as I had my sign in for FireFox I could restore them on my system.

Alas, I cannot figure out how to do this. I do not have a passkey, a profile or anything other than the email address for my system.

Can you help me? I put all of my important documents in Dropbox and now I can;t access that either.

Anything you can do is appreciated.

Hello, I was using a cleaner program called "Cleaner One Pro" and I mistakenly let it clean my main firefox profile, and then I backed up my system afterward, unknowingly overwriting my recent backup. When I tried running firefox again, it had regressed to an earlier snapshot of my profile and was reloading all my tabs as well. Also, all my previous sessions and my history was all erased. This program should not have erased those, and if it had not, I could have simply let the tabs reload and been fine. So my profile was left in an earlier state with no way to recover current tabs. I have many, many, many open tabs on firefox, which has NEVER been a problem whatsoever. All my tabs were in an earlier version. I, however, found that firefox had made a partial backup of my profile into another folder in the same folder as my profile, but this backup was not complete, and trying to use it as a complete profile resulted in only a few tabs open at all, worse than even before. But this limited backup included my complete, current history. Are there any other file or files in this limited profile backup that I could use to restore my open tabs? I am using the absolute latest and newest version of firefox. My sessions and similar files are missing from both folders. It seems this funny little partial profile backup was made, and I was hoping there was a way to restore my open tabs from this little, smaller, partial firefox backup profile folder. Has anyone ever seen this, and how can I recover?

As of now, I restored an 11-day old profile and was able to import my new history into that using an extension, and if worst came to worst, I could at least recover my history and all the sites in that time of the missing 11 days I had went into, but I was hoping to recover my current tabs from that time as well. In this limited profile backup folder that exists next to the profile folder that was trashed, Is there any other file besides the session files that could have stored my open tabs, that I somehow didn't see or know about, which I could use to get my tabs back? I would willingly let firefox reload my tabs if possible to restore them as they were before this happened.

Thank you very much,

Gino Costa

Hello everyone. This is more of a review, because it is impossible to get help from these forums, effective help (judging by the AI-based answers) And it is impossible to write a review or suggest an idea, since the site does not open, which is ideas. Maybe because I'm from Russia. About six months ago, very serious problems started with the browser. I have Windows 11, a completely modern computer, and Kaspersky anti-virus. And the problem arose like this, from time to time, the browser began to multiply images in the tab, i.e., a random part of the image in the browser appeared instead of another element. And gradually the whole tab turned out to be in the form of a puzzle. This was accompanied by an actual system freeze, treated by logging back into the Windows profile, or rebooting, in the worst case. Simply put, the browser began to produce completely incomprehensible errors. And if it didn't bother me too much at first, I logged back in and that's it, in recent weeks the error has started to occur even during active browser use (it usually started after half an hour of inactivity) In recent weeks, the puzzle in the tab has appeared quite insanely often. By the way, there are no messages on this topic on the Web at all. And it's impossible to take a screenshot of the error, as the system was barely working at the time. As a result, I just reinstalled the browser, once again losing a huge number of open tabs (there are, of course, more than a thousand in the log, but there is no option to Open them) The ways to save sessions from the forum do not work at all, the extension of the Tab session manager did not work

And the review, in fact, was once a beautiful Fox, now it's not even a competitor to chrome. Which allows you to save data and restore it without unnecessary problems. I have installed Mozilla Firefox again, but all data will now be backed up in Chrome. Mozilla Firefox is just for surfing the Net. I would like the developers to think at least a little about user convenience. By making it convenient to work with data backup and recovery. And to make it work at all. By the way, the topics that AI advised me to read in the Firebox problem solving search rarely have more than 52% positive reviews. Is the browser really so poorly made, by modern standards, that almost half of users can't figure it out? And even tech support itself gives out standard tips that can't help.

This is my last message here, there's no point in answering.

When I turn off my computer at night I have my bookmarks. But, when I turn it back on in the morningm on the top left I know longer have the option to click on bookmarks because that word isn't showing, anymore. Can I have a phone number at Mozilla to call to get this resolved?

Thank you

I recently updated Firefox on my computer. After that, I can't find my old Bookmarks.

Also I find that I am UNABLE to add any new Bookmark. When I click on the 'Star' in the browser toolbar, there is nothing. Before I used to Get the Add Bookmark tab and a place to SAVE, now there is nothing.

Even after I type in the URL in the address bar, and open up the required page, I am unable to Add it to my Bookmarks.

Please Help!

I am currently using Windows 10 Pro and wondering if putting off the change to Windows 11, will only multiply the number of potential losses, especially if I have disabled One Drive? I have 2 Desktop PC's and two laptops. all but one laptop(its running on 11 Pro), are running on Windows 10 Pro. Do Firefox users recommend taking Microsoft's offer for a free upgrade to Windows 11?

I want to be able to sign in and provide my own backup locally. I would also like to save a word document directly and with the shortest path possible; going from "User/my-username/documents" (same applies to all other data saved, like photos, music...), and not be forced to save to Microsoft's OneDrive. What is most disturbing about One Drive, is that it could be an additional option with its own pathway, rather than holding owners captive to Microsoft and it's objectives that are not chosen for my best interests.

I wonder how many Windows users even know that all of his/her information/data are First saved to a Microsoft cloud. Norton shares the options with you and gives the user the choice to backup in it's cloud

I don't have a problem of having my computers locally synced, but I do not want to be trusting Microsoft to have my computers sync in it's cloud. I personally, do not have any critical reason to have all of my computers sharing information. My desktops are each being used for unrelated tasks.

When/if the day comes that corporations like Microsoft, share it's suggestions, and are allowing the user to choose from the beginning, rather than making decisions for the owner of his/her computer, forcing them to discover what Microsoft has chosen and how to undo the choice without the risk of losing one's data; I will want to use my PC's locally, without being forced to log in with a Microsoft account.

I have read and watched many reviews that are suggesting/wanting to exit Microsoft's "ownership" of his/her computer, providing ways to turn off choices like One Drive and/or remove it completely.

Does Firefox have an opinion on this subject(emphasis being One Drive) and will I be OK with my Firefox account providing a backup of all data related to my use of Firefox? I have each computer backed up locally. Until things are turned around and all choices are turned back over to the local owner of his/her PC, I have a hard time of trusting any corporation selling my information.

I'm 84 and know little about computers - when I try to get into e-mail it says "program running but not responding" How do I correct this? Please help. Since I can't open my e-mails you can't reach me. Phone: [edited phone# from public community support forum]

I am trying to preserve my POCKET data before it all goes away. Mozilla responded to my email requesting data but when I opened the link I got this message that "the provided token has expired : despite it being less than 24 hours. Plus a lot of other characters meaningless to me. What can I do now?

This XML file does not appear to have any style information associated with it. The document tree is shown below. <Error> ExpiredToken <Message>The provided token has expired.</Message> <Token-0>

I bought a new computer 7-1-25 and I wanted to contact you about problems with your update, but it rejected my Acct Key - and when I looked at the email I got with the acct key it said Windows 10 - which tells me someone hacked my old acct because I have Windows 11 as of 7-1-25!
