I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

Hi there! I find the new sidebar (on the left for me) a great addition but is there a way to reverse the "top to bottom" tabs displaying order?

Not a way to move tabs, but a setting allowing, when opening a new tab (Ctrl+t), to place (and display) the icon on top of the tabs icons pile, not at the bottom.

I get that it's the opposite of the normal reading direction, but it's rather unnatural to go looking at the bottom of the screen for recently opened tabs, IMHO.

Thanks in advance if you can address this, or show me where I can find such setting.

Best regards from France, Jc

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Hi a few weeks ago i had the problem that my firefox-stored-passwords are gone and there are files named logins.json.corrupt and logins.json-1.corrupt to -4 The in dir backup was also corrupt. File length 122 -123 kb all nulls. If i look at the dates first to last, they span two weeks were i didnt notice the problem. PC is always hibernated after work. Except for one which i imported just before from edge at the end of the two week span No problem: logins replaced by external backup as i found here at the forum.

But: How can Firefox produce multiple corrupt files without noticing me? (I have saved them for reference) In that two weeks span logins using firefox passwords obviously worked. (I dont remember the details)

Then some updates and reboots. No problem. But after work i do always hibernation

TODAY: PC didnt survive hibernation. logins and in-dir backup are corrupt again.

What about a) checking better if something is going wrong (obiously you do something because you rename the files for some reason) b) Noticing the user c) And how on earth this can go wrong in the first place.

Now for the obscure: Both times somebody has just before posted something against the greatest President of all time at Fux Nus using this pc. Backdoor possible?

Thanks

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

Tonight I received a notice that a new version of Firefox was available and asking if I wanted to download it. It showed me the new Kit mascot so I decided to let it install. It seemed to install normally but when it tried to open what I guess is a welcome/new features page, it crashes, and just showed a prompt to try again. This continued in an endless loop and I had to shut it down. Unfortunately I no longer had a functioning version available that I could find so I downoaded the ESR version to be safe (ver 140.5.0esr) which I am now using. Somehow I was able to recover bookmarks and hopefully other saved info. Can anyone advise what has happened? I have used Firefox for many years and never had this sort of problem before. Running Windows 11 on a new Dell i7 PC.

After the 145.0 update when I start Firefox both the menu bar and the top bar with the exit icon are missing. This is the first issue I've had since using Firefox when the new revision was in the 20's. Per some quick Support research, I press F 11 twice (NOT once) to restore the screen to include the top bar with exit icon and menu bar with my Windows task bar showing (as normal for the past 2 decades). When I close out Firefox in less than full screen mode and then start up Firefox again, it properly includes both the top bar with exit icon and the menu bar. HOWEVER, if I close Firefox in full screen and then restart, I am missing the top icon bar and menu bar... again. Press F11 twice and the bars are back to square one. HOW DO I FIX THIS SO I DON'T HAVE TO PRESS F11 TWICE ON EVERY STARTUP TO RESTORE MY SCREEN?????? WHY DID YOUR RECENT UPDATE CHANGE MY SCREEN SETTINGS?????

Hi, there.

After performing the most recent Firefox update, I was greeted with the "create a new profile prompt", rather than having it open my old one. When going to "about:profiles", ALL FILES in the Root Directory of my old, default profile have the same date as the update, or after. Not a single file is older than that and all my history and bookmarks are gone. The option "Restore Previous Session" was not shown after the update.

PLEASE HELP!!

Thank you.

PS: This happened on a Macbook Pro. All other profiles are the same as they were before the update, having kept all history and bookmarks.
