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.)

Guten Tag, Ich nutze 4-5 Fenster, je nach Anwendungsumfeld, dauerhaft. Die Fenster beeinhalten meistens die jeweiligen Log-Ins in den einzelnen Tabs. Aus irgendwelchen Gründen sind alle meine eingerichteten Fenster verschwunden. ich habe versucht, über die Wiederherstellung der letzten 7 Tage meinen bekannten Stand wiederherzustellen. Da wurden mir ca. 750 Tabs angeboten. Der Versuch meine Fenster/Tabs zu finden war schier unmöglich. Also habe ich versucht alle! wiederherzustellen um manuell den Stand meiner Fenster zu rekonstruieren. Hat nicht bzw nur teilweise funktioniert. Können sie mir helfen meine Fenster mit den entsprechenden Tabs von vor 3-4 Tagen wiederherzustellen?

Vielen Dank

My geeksquad agent dumped me here. They were not able to fix the issue. My tools are not all on the bar, my book marks are not all here. They got some. There was a message that some other application was using my firefox and my tools and bookmarks wouldn't work. I am no tech person. I just want things back like they were and to know why this happened and I don't want it to happen again. Please help.

I tried a restore but the only date available for bookmarks was today (jsonlz4 file). I tried other online suggestions but I cannot locate any old files to restore from. If I cannot get them back, I will switch browsers because the loss is unacceptable.

For the past, about 9 months, every time any update is applied to my Firefox browser, I loose access to my Bookmarks (approx 10 years worth) and have to go through the tedious process of copying, renaming, moving, restarting etc. Is Mozilla going to fix this issue soon or should I just resign myself to having to check my bookmarks every couple of days or so to see if they still exist.

I accidentally messed it up when trying to remove the desktop icon because I already set Firefox in my taskbar. Now I get an unfamiliar screen and my settings, including bookmarks, are gone. Is it possible to set my laptop to undo changes made today?

Firefox suddenly reset to a fresh install state: only default bookmarks, my custom ones are gone. No sync enabled. No manual reset/refresh/reinstall done. Tried: Restore from backups (none recent), about:profiles (only new profile), checked bookmarkbackups folder (empty/old). Please help recover bookmarks if possible. What could cause this? Any recovery steps?

My bookmarks toolbar shows but it is blank. I had 60+ bookmarks on it. Why did Firefox trash my bookmarks?

Why did Firefox force me to create a new profile? I can get to my old profile, but the bookmarks toolbar is blank. The bookmarks showed for a while, then the toolbar went blank. What gives?

I have had all kinds of problems with Firefox the past several years, and I am about ready to can Firefox and go with Edge and Chrome. In my opinion, Firefox is a piece of crap, and I am fed up with it. I already have Edge and Chrome, but mostly use them as a backup when Firefox doesn't work right.

Is there any hope Firefox will get better, or should I jump ship with the other rats fleeing this despicable piece of junk? I have been hanging onto Firefox, because I am familiar with it and used to like it, and have used it for over a decade. But my patience is growing thinner.

Why my mozilla account didn't save my bookmark correctly, I just upgrade my windows to Windows 11, before I install my OS, I already syinced my Mozilla Account and all its data include bookmark toolbar. But, when I try to login and resync all my old data, its all gone, how to solve this issue?

Help me download a new Firefox app and show me how to find my former apps. I clicked on Profiles and my previous app came up. Now how do i save it into a new app/or save it?

Firefox was working fine yesterday morning. I went to log in last night and a new firefox background was there. NO bookmarks, NO history, No Nothing! How can I get my old information back?

Hi,

Today I was suprised to see that my shortcuts were deleted so i tried to fix it, but instead i somehow deleted my profile which had everything, is there a way to bring it back?
