I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?

Hello,

I just had Firefox overwrote a session restore I had open for a long time with a few hundred tabs. Is there any way to see prior session history or backup these sessions without manually copying the files? If not will these features ever be added?

Thanks

Yesterday, 50% of my bookmarks were deleted and now I can't bookmark anything. I tried to restore my bookmarks to several previous dates, but I received the following message each time:

Unable to process the backup file.

I tried to bookmark different websites and no bookmarks are saved now. I updated to the latest Firefox today and no change.

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

All my bookmarks and history were erased when Focus was (automatically) installed. Same with passwords generated by Firefox. How do I get all this back? It should be in my original profile, but that seems to be gone, too.

I am trying to find the files for my passwords from an old profile after Firefox just updated and created a new profile. I have just created a Mozzilla account so my profile can start to automatically update with all of my old passwords, but I first need to manually transfer them from my old profile that didn't have a Mozzilla account yet. I have been following the steps for doing so from the "help" pages, but I haven't been able to find the files for my passwords.

I was prompted to do an update today and it erased all my bookmarks. I have a saved bookmark file that is a JSON file type but it won't let me import that b/c it's not HTML. I have a lot of saved bookmarks for work and really need to get them back.

Hello,

"The bookmarks and history system will not be functional" error message has suddenly appeared in just the past couple of days on my new DELL Inspiron 15 3535 with Windows 11. I have followed the first few items on the Mozilla Support page that comes up as soon as the initial Firefox opening page appears and that has not corrected the problem.

I have tried to follow the next few steps but can't really find what it calls for because I don't understand what it's talking about. I am not of the tech generation and do not speak the tech language. Most of the terms in there I do not know what or where they are on the laptop.

Is there anybody who could help me saw through the terminology and give me some ideas on how to simply solve my problem? All I really want to do is get to where my bookmarks are hidden and put them back in place where I can use them again.

Thank you in advance for any help anybody might have.

Kind Regards, Tom B.

I went away for a week, and during that time my iMac (apple desktop) turned off. When I rebooted it last night, Firefox loaded at the start as it has for years, but ALL of my bookmarks and activity history was gone. I've been collecting those bookmarks for nineteen years, and while there's a lot of useless stuff I've collected over the years, some of it is very important.

Please help.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!
