After opening up Firefox to continue work in one of my Saved tab groups, I noticed the 153.0 Update window.

All my saved tab groups have been deleted and the tab group options have been replaced with the new Tab container system in the drop down menu. I even made a new group to test and it saved and was accessible but all the important ones are gone. Nothing in the Json files, tried most of the solutions I've read online. none of these work.

Saved Tab groups don't to sync across devices and are local, so surely they should be saved locally on the system.

I was switching computers and created a backup file. The type was html oddly. I tried to restore this backup on two different computers and both times it fails during the restore process without presenting a useful error message.

I can only guess that the file is corrupt, but it is only a guess since the error message is useless. It also seems strange that the backup didn't produce any errors (manual backup). Any suggestions?

I have been using Mozilla Firefox on my mobile phone or PC since 2015. So, after so long, I found the Gmail that I used to log in to Mozilla from 2015 to 2018. Now, if I log in with that Gmail, will the previous history or data be restored or will it be Mozilla's?

Logged on to find this message. Followed "Fix" set as best I could (I am puter dumb) with no joy. "Manage Bookmarks" is completely blank. All wits end, Please HELP!

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.

Foxfire updated a couple days ago, when it did it lost all my latest saved bookmarks. When I go to uninstall that maintainese package, I am denied access to do so.

Running Windows 10 but with extra year of security updates. Several web sites were running very slow or not loading at all. So I tried doing system restore - only went back 3 days but afterward said it had some problems, and link to Firefox did not work. So I did system recovery back to time from which I had just done restore. But I had no link to Firefox so had to download it new. But now I have none of my previous tabs, links, saved passwords,,etc. I'm hoping my previous Firefox is still on my PC and there is a way I can run it.

ich benötige die übermittlung, da das chronic dieses eingestellt hatte: die auffindung der www´s durch das vorgehen bei dem umstellen der mozilla-umsetzung bei der neuinstallation. durch dieses hatte ich die www von einer bestimmten auffindung nicht (ich kann die www gern durchgeben: frau, bdsm, in der nähe, aber ohne kommerziellem hintergrund !).

all your articles on 'Session Restore' or Restore Browsing History, are GOBBLEDEGOOK! links that do not work or are incorrect information! Steps which do not work or lead to a previous page which was not helpful ! " Recently Closed Tabs" or History will NOT open the latest tabs. Click to ??? "whatever" is incomplete 'cause you do not tell us WHERE IT IS LOCATED. Backup" is assumed by you, but no information to set it up! Bottom line.: when Firefox crashes, we [the user] is screwed!!

What the hell has happened to the support environment? I've tried to resolve two big issues recently, and I can't find anything of value. I've lost the ability to pin an extension to the toolbar after losing my entire profile on this computer, tabs and all, using Tab Manager. I can't find a way to recover the profile, so I've given up on that. Now I can't get my most-used extensions back on the toolbar.

This first happened a few days ago and I successfully recovered my book marks from backup. It has now happened twice more. I can't be sure, but it seems possible that this happened each time after installing recent updates. Note that my recent history has also vanished.

Per Updates critically important open tabs were no longer accessible following the Updates in question. I need to recover the missing activity-chronic or request that the unfinished activity up to the point of Update be retrieved.

I used Firefox yesterday. My settings are to open Firefox with tabs restored - but all my tabs (as they were yesterday) are missing and when I go to history, the option to restore a recent window is greyed out. The option to restore a previous session doesn't even seem to be there.

I notice in task manager I have 15 firefox tasks. Could my window from yesterday have opened somehow in the background, but not be visible to me anywhere?

and how do I fix it so I can restore previous sessions I accidentally close? I accidentally deleted all prior data from whatever version of Firefox I was using the other day (I didn't have a profile as far as I'm aware) removing all saved passwords, bookmarks, history, and apparently the Restore function.

I had my computer fixed due to a virus and now I can't get my old firefox with all my saved passwords back. How can I get it back. I'm using my same email address.

Firefox unable restore session when switching profiles and instead opening apps installed on the profile I'm switching to.

I have installed Whatsapp web (web.whatsapp.com) on "Profile 1" as a Windows app.

I have some tabs open in "Profile 1" and I switch to "Profile 2" and close the "Profile 1" window with "X" button of Windows 11 but keep the Whatsapp window open.

When I open the "Profile 1" from profile menu, my expectation is that, those previous tabs should be restored, but firefox is opening the Whatsapp web app/window.
