I ran into a glitch in another program, and as part of trying to fix it I rebooted my computer. On doing so, I find that the VAST majority of the tabs I had open in my main browsing window have disappeared - some of them out of tab groups I'd created to avoid losing the tabs in question. Neither tab history nor browser history show the missing tabs.

What gives?! Is there any way to restore the window as I had it, say, yesterday?

Synced my new computer, received bookmark toolbar and 10 year old bookmarks from when i switched from interent explorer, but all my more recent bookmarks and bookmark folders are still missing on the new computer. Also didn't seem to transfer passwords and autofill info.

I don't what or how it happened.

But one night all I can remember was I updated my Firefox in Windows and my account was synced. I use to have all my browser history on my Macbook air. But suddenly the next day I discover that all of my history is gone. I have no idea what caused or how I can recover it again. I tried the internet and nothing helped me with my problem. So now I'm resorting to this and hopefully someone can tell me what to do.

Hello, I recently had 20+ tabs open in Firefox. I moved 1 tab of the 20 to be a separate page and closed the other tabs. Now I am unable to re-open the other tabs through the 'Recently Closed Tab' feature. That feature only shows a few new tabs I opened on the separate page. Is the only option to painstakingly search through history over several months to re-open several tabs I had open for several months? Thank you the feedback, Ken

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Moved to different pc, logged into my account, all bookmarks gone. What is going on? The sync even synced with empty bookmarks, and I guess everything I bookmarked is gone now.

I factory reset my pc and i logged back in to my firefox account and all my saved log ins and book marks are gone did i loose them for ever or is there a way to get them back?

AFTER 137.0.2 EVERY TIME I START FF ALL MY PREVIOUS TABS ARE GONE AND I BACK TO THE TOUR SCREEN. ANYONE KNOW HOW TO FIX THIS, BESIDES SWITCHING TO ANOTHER BROWSER?

Hi, is there a way mozila can help me to retrieve all my remember login ID and password? due to i changing to new laptop and when i sign out it ask me to delete all the old password which i thought is just delete from the laptop instead of my whole login ID and password.

Last week I deleted browser data & cookies (for a Microsoft account I use) & then I accidentally used an incorrect password to login to Facebook & they locked my account. When I tried to change my password they didn't recognize my device, which I've been using for MANY years. They also reject photos of my i.d. & won't tell me why because I'm apparently trying to communicate with an a.i. bot, NOT a human being. P.S. To make things even worse, I was locked out of my phone, which kept asking me for a password that I've NEVER set up. So I had to do a factory reset & lost ALL my data.

I've tried everything I can think of & I'm wondering if it's possible to get at least some of the data back?

What a mess! After 136.0.4 was installed today and I rebooted my laptop, Firefox acted as if it was an entirely new installation. No bookmarks, no saved tabs (Tab Session Mgr extn was completely erased) and all custom settings eliminated. Any ideas about how to reverse this?

I signed into and synced my Firefox acct, which returned my bookmarks (albeit with generic icons that don't identify the sites). But no tabs have returned. Any my synced tabs history does not show everything that was open.

I'm now spending way too much time relocating and recreating what I need. This is not the first time Firefox is causing me recent pain (see prior post) and I'm again toying with leaving Firefox, as I periodically do when the platform becomes unstable and unreliable.

I love all the folks at Mozilla, but this simply cannot happen.

Firefox updated to version 137.0 (64-bit) on 4/1/2025 and deleted all of my Favorites. I tried to restore them from Manage Bookmarks - Import and Backup - Restore - Choose File. Choose file does nothing. I restarted the Windows 11 PC with no change and deleted my Extensions.

Придется вам как-то перевести самостоятельно то что написала на английский. Зачем писать что при обновлении все будет сохранено, если после обновления, половина окон на восстановилась и история предыдущих посещений пропала.? и как мне теперь все это восстановить обратно?'

I had a issue with my Dell laptop, when it was resolved It had deleted Firefox. They created a new one, but the bookmarks are gone. I have looked at the information on recovering Bookmarks, but still cannot recover my bookmarks.

Can I get help on this issue?

Thanks,

Riley
