I have suddenly lost all my firefox data today.. after creating a new browser profile? I never bothered creating profiles and stuff when the update for that came and it seemed like Mozilla never forced me to create named profiles until today when I open it again after booting up and it suddenly asks me to make a profile for the browser and after I did I just saw that I lost everything, I have a firefox account that's sync to my mobile phone but I can't seem to sync it neither, my browsing history, bookmarks, and passwords are all gone and I've even checked the AppData/Roaming/Mozilla/Firefox folder for it and even the recycle bin but I can't seem to find a single trace of my data before firefox forced me to create a browsing profile for my computer. Hoping someone has a solution to this.

Mozilla-Team,

I am / was such a huge fan of Mozilla. But now I lose my qualitity of being patient. This Update window coming up more and more. But there is no way to find - especially not an easy way. I need to make a new installation of the full programme. While doing this, I lost my full bookmarks. No chance to recover after five hours. I am really mad. Really mad.

I will leave Mozilla soon, if you dont tell me, how to use your browser without trouble.

the last update of firefox wiped out my amazon account on my pc. It completely cleared my calendar. Messed with my passwords on some of my accounts. Can someone tell me how to get these things back. I am not a computer wiz.

after Firefox update all bookmarks stopped working and are not editable. All tabs crash, including Firefox help link from the Firefox menu.

Password list is blank - no entries

Is there any way to retrieve bookmarks?

I need to enter each url in the browser line and save bookmark for it to work.

Can you please help?

When Firefox updated I only created a default profile and could not or did not import bookmarks. They seem lost now. I was offered to import from other browsers like Edge but did not see any way to import from my previous Firefox version. I am unable to find any automatic backups in bookmarkbackups folder.

I have my browser.sessionstore.max_windows_undo in about:config set to 60 – it's been like this and working fine for several months.

It's set to this high number because I use an assistive technology which creates a fresh pop-up every time I deploy it, and Firefox treats it as a browser window closure when I close the pop-up. Consequently, I can easily rattle through well over 25 window closures in a day.

It's not necessarily that each window contains dozens of tabs and copious data, but nevertheless Firefox still treats it as a window 'within the meaning of the act'!

I just went to reopen one closed window from a couple days ago which did contain many tabs (partly why I closed it in the first place), only to find that the 'recently-closed windows' context menu is now only showing 20 windows (18 of which are the aforementioned pop-up assistive technology windows)

The really vital window that I want to reopen is not showing.

I've double checked in about: config and the browser.sessionstore.max_windows_undo is still set to 60 windows; nothing has been altered or reset.

I updated Firefox to 147.0.4 yesterday evening, but the problem existed before I updated Firefox, and is still in evidence since updating.

Two questions:

1) Why is the Recently Closed Windows context menu not showing the full number of windows it has been successfully doing with no problem now for months? I used to have to scroll down to access the full extent of the 60, but they were always there.

2) Why has it arbitrarily changed to 25 windows?

3) [I lied – Our chief weapons etc...] Is there a way that – given about:config still implies that the most recent 60 windows are retrievable – that I can access beyond the 25 windows limit that are currently showing as reopenable?

Thanks very much

(And yes, I already have things like OneTab and Tab Session Manager add-ons, but disabled those just before closing the important window, because I was trying to locate which add-on was draining the CPU. I assumed my 'recently-closed windows' buffer of 60 would suffice while I disabled the add-ons.)

Randomly my firefix just get loggedout and when i immediately logged it in again using mozilla i cant see my bookmarks my other accounts my profiles and all my groups and other information it was like i had made a fresh account all my data is lost what to do ? PLZ help i really want my data back i have been trying to get my data. Working on it for last hour.

My old laptop is broken; I can no longer access the hard drive. Is there any way I can reorganize my old bookmarks from before a specific date, i.e., December 15, 2025, in Firefox?

I use a SAAS solution for my small business (FreshBooks) that has not been working well with Firefox as of late. When I reached out to their customer care department they asked me to follow their resolution steps, which included wiping the cache and cookies for all of my Firefox browser. I did so at their request, it did not fix their issue (it appears to be something their developers are working on solving) and subsequently I lost a lot of retained other sites log-in and history. Is there a way to restore the cache cookies that were removed yesterday? Appreciate your help,

help me restore my open windows. this has also happened a couple times before and its very frustrating when i have tabs open to read/refer to later or am in the process of reading and then i have to try and find them all again.

When accessing my bookmarks list, I clicked on the wrong location and my whole list of bookmarks disappeared; left me with tabulated folders. How do I get my list of bookmarks back?

I tried to remove the new 'profile'. I don't want it. now ALL my data, settings & bookmarks are GONE ! Help me revert to & restore the previous account settings !!!!!

There was an update with Mozilla Firefox on the 8th. I had tabs open on the computer. After the update, I could not retrieve the tabs I had open. Tried to restore and nothing worked. Is there any way to restore my tabs?

Ich habe die Passwortliste bei Einstellungen aufgerufen und die war leer und alle gespeicherten Passwörter waren weg. Ich habe sie aber nicht gelöscht. Wie kann ich die Liste mit den Passwörtern wieder wieder herstellen ?
