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! 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.

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

Hi!

I appreciate all the work put into developing 155, and I can't keep up. I'd like to get my book marks back. How can I return to an earlier version, unless you know a way I can get them in 155, Thank you! BTW I'm using Windows 10.

Hello I've made backup file today before uninstaling my OS. Now I want to restore data afrer reinstalling my OS, but I keep getting error. Error added. Please help me to restore my data!

I was reinstalling my windows and created a backup from my old firefox into my usb drive. My backup failed and coudn't be restored, I'm confident that I use the correct password, tried to copy the file from usb drive into my laptop and select it from there but the result is the same, if you guys would be so kind as to guide me on how to restore my backup, since my password and everything is in there. I didn't create another backup since I believe that this one would succeed. Thank you in advance.e

RE: JBR posted an answer to your question "All bookmarks disappeared. I found my json backup files. How can I import this file into Mz, now that it has created a new, dysfunctional 'profile' ??"

Today's update to Fx re-established the link between 'import' and my .json backup files of my extensive, organized bookmarks.

My genuine thanks to all involved in this crucial repair!! Ken Westphal

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!

Acer Aspire 5 laptop. Windows 10. Auto turned off because I unplugged it to move places and it has a dodgy connection so if the screen physically moves a bit (like closing and opening movement) it just auto turns off - the screen accidentally moved a bit! I restarted it but only used it to connect to the scanner and save the scanned doc in Documents - I didn't use the internet so didn't realise the tabs didn't re-open as normal. Next day, I realised the many tabs and a few windows weren't opening in Mozilla Firefox. They were also off in Chrome but I could recover those - and it was just one window and a handful of tabs. I did a restore last session, which was dated as a couple of days previously, but the Firefox windows and tabs were still not there when I restarted. I certainly wasn't asked nor were there any warnings re saving tabs etc Firefox has just done an update (auto). I've looked around but see no solution. I don't have my laptop synced to any other device. I thought I had a back up / remember things for in case of crashes but it seems not. What do I do to recover all the tabs and windows? Thank you.

So my friend uses firefox (not signed it) & called me over to ask where it's tab groups went. I come over to look & they're just gone. I look to see if I can save new ones, can't, so I update firefox to see if the issue is that perhaps. It brings the ability back, but the previously saved & closed tab groups are still gone. Going to the previous/default(?) profile thing didn't work, so we're not sure what to do. Still looking to see if I can salvage them from history or just find them but Twitter & Tumblr can be hell to look through, especially twitter.

Also I don't know what topic this would fall under, so the topic thingy may be incorrect.

I'm running Windows 10 (from which I'm writing this), but I recently installed Firefox on my new Windows 11 laptop. Could this be the source of this (or other) problem(s)?

You did updates this morning which annoys me anyway. You do updates too often and at the wrong time of day. After you did updates, everything, all my bookmarks, etc. are gone. It's a blank screen.
