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.

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

Differences between implementation of :has between FF and Chrome.

FF bug (?) (my own tests), Chrome works as expected, was also gemini ai discussed.:

 Why for the following css rule (new FF):
 header:has(~ noscript) ~ * div[class*="-slider"] {width: calc(var(--number-of-slides) * 100%);}
 the --number-of-slides is defined and visible:
 header:has(~ noscript) ~ * div[class*="-slider"] {--number-of-slides: 1}
 but this one isn't at all:
 header:has(~ noscript:has([value="1"])) ~ * div[class*="-slider"] {--number-of-slides: 1}
 And all remembering that in the noscript there is direct descendant having value="1"

As mentioned it works as expected (so average person naturally may think it sould) well for Chrome - noscript is visible, js disabled, controls are visible. Sophisticated use case of :has() but it sort of "has right" to happen.

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

After upgrading my Firefox to version 145, a blue line appears at the top of the browser window when it's in full-screen mode and the current window is focused. I know this is to remind the browser window that it's currently focused and interactive, but I really hate this notification and want to make this conspicuous blue line at the top of the window disappear. I couldn't find a relevant option in the Firefox browser settings. Does anyone know how to set this up?

Please help me to disable this focus tip,thanks!

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.

  • Vulnerable Password

  • This password has been used on another account that was likely in a data breach. Reusing credentials puts all your accounts at risk. Change this password.

Except I know the password is unique.

I have a strict username / password usage where every site gets a unique password, period.

The problem seems to have started after a browser update. Running up-to-date Windows 10. This issue does not occur when using Edge. Youtube videos are blank (spinning). Sometimes it results is a still frame, other times it spins forever. Many times, you can see a series of stills in the video as the time line is dragged from the beginning to the end of the video. A small number of videos will work, but I have not been able to predict which will work or why. A different Win 10 machine on the same network is fine. I have tried all of the solutions I could find searching on-line (clearing cache, cookies, reboot, restart, update browser software, etc, multiple times). Checked settings in windows, firefox and youtube looking for something. Any help would be appreciated. Have used Firefox for decades and I don't want to be forced to change browsers.

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??

I have an Investors.com account and a feature they offer is a stock sector data table that shows recent performance and other information. When I try to open these tables they close immediately, but if I use my tablet with a different browser they will remain open. I believe this is a simple setting that I need to adjust, but I don't know enough to figure it out.
