I-Firefox Community Forum

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?

Seit dem letzten Update auf 153.0.1 sind alle Lesezeichen aus der Lesezeichenleiste verschwunden. Die Wiederherstellung aus der .json- Datei in meinem FF-Profilordner, in dem sich die 12 Einträge befinden funktioniert nicht. Wie kann ich die Lesezeichen wieder herstellen? Ich habe keine Admin-Rechte.

Leider hatte ich FF auf automatisches Update eingestellt, das hab ich jetzt ausgeschaltet.

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.

OS: Windows 11 23H2 Firefox: 152.0.4

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.

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.

2021 Macbook Pro Sequoia 15.7.4 Firefox 152.0.3 (aarch64)

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.

All but 2 of my previous saved windows have been lost. They are not recoverable or present when trying to use "Recently closed windows." How could this happen? More importantly, how can I recover them? They contain numerous tabs that will be impossible to recreate from memory.

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!

""What happened:"" Yesterday I updated Firefox to 151 and noticed a "Profile" feature for the first time. I created a new profile, then saw a small icon with the Firefox icon that bothered me and realized it belonged to the new profile. I thought that the newly created profile is safe to delete and has to data within, so I deleted it. After that, Firefox deleted all old data and created another new profile and I lost old bookmarks, passwords, and browsing history.

Note: no warning was showed before deleting the profile.

What I tried: 1. Checked about:profiles profiles: no old data. 2. Opened the profiles folder in C:\Users\[my account]\AppData\Roaming\Mozilla\Firefox\Profiles: no old data found. I noticed one of the default profiles contains a places.sqlite file that’s about 2 years old: no old data, only default bookmarks are there. 3. Used Recuva to try to recover files — I recovered key4.db, login.db, and places.sqlite-shm but nothing useful so far. Environment/details: • Firefox version: 151 • OS: Windows 11 • No Firefox account Questions: • Is there any way to restore the old profile data from the files I recovered (key4.db, logins.json/login.db, places.sqlite-shm)? • Any other recovery steps I should try? • how to prevent the same thing in the future? Thanks

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 !).

Locking this thread, please continue here: [/questions/1583232]
you have removed ALL my bookmarks every time I reboot Firefox. This is intolerable!!!!!!! You have cost me 24 hours of insufferable time trying to reinstall my hundreds of bookmarks.

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?

How can I Recover Deleted Firefox (build 151.0.2 (64-bit) Browsing History in my version/edition of Windows 11 Pro, Version = 25H2, installed = 12/06/2024, OS Build = 26200.8524. Can you help me recover my Browsing History from Friday, 05/29/2026? Please.
