Firefox Community Forum

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.

Website: https://www.londonpicturearchive.org.uk/view-item?i=119810&WINID=1764158938344 (for example) On Safari I see there is a message overlay from the website saying "press the command key to zoom the image". On Firefox, this message is not displayed, and the website is greyed out.

I have looked at all my settings: I can't see anything wrong. Any ideas?

Is there a fix or workaround?

Hello,

In the latest update I got it made everything into rounded corners. The Tabs and Settings windows as an example. How do I undo that?

I checked thoroughly in the appearance settings and dont see a way to do that. I specifically switched my entire world over to Firefox to get out of the rounded corner UI world only in time for this switch to happen. How do i undo it?

its pretty much what it says on the tin, im not seeing my channel points in chat

 i have turned off all the tracking stuff 

i turned off the enhanced tracking and i still cannot see or earn my channel points i have turned my site security to nothing to see if that would do anything I have turned off all my add-ons and they just dont show can anyone tell me whats happening here

I have just upgraded to version 145 and the title bar has disappeared Even though I have the Title Bar option checked in the customize firefox panel. If I uncheck the title bar option and then check the title bar option, the title bar will appear, but when I close firefox and then restart firefox the title bar is gone.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

At your recommendation I signed up to Ad Avoid and now FireFox tells me that I could/should not access BT.Com because of the certificate issued by Ad Avoid

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?????

I see in one of the past recent updates, I notice that "- Original Profile" is in the windows and not just the title of the website I'm on. Any way to remove it? It looks off and not necessary to me.

latest version of firefox will not let me save a password on a new website, it has always worked before, see image for settings. website is not included in exceptions

Hi

I need to block some sites through the OS Hosts file, Other browsers ( Edge, Chrome, .. ) are honoring the HOSTS file rules but Firefox bypassing them !! , I disabled the DNSOverHTTPS and all other available suggestion and options but still not honoring the hosts file !

as you can see in the attached file, the Firefox DNS Section is now blank ! but still doesn't follow the OS host file

I even made a custom policy file but still doesn't work, these are the things I disabled but still not working :

{

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": false,
     "Locked": true
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 5,
       "Status": "locked"
     },
     "network.dns.native_https_query": {
       "Value": false,
       "Status": "locked"
     },
     "network.trr.uri": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.bootstrapAddress": {
       "Value": "",
       "Status": "locked"
     },
     "network.trr.exclude-etc-hosts": {
       "Value": true,
       "Status": "locked"
     },
     "network.dnsCacheEntries": {
       "Value": 0,
       "Status": "locked"
     },
     "network.dns.disableIPv6": {
       "Value": true,
       "Status": "locked"
     },
     "browser.fixup.dns_first_for_single_words": {
       "Value": true,
       "Status": "locked"

Hi there I have the problem that my firefox can save any file or download on my other drives since they arent event show as an option. I did a little research and read that by default in linux for security reason was unable to, but asking in the official forum of my distro (cachyos), they can save thing in other drives with no problems.

So i wanted to know why i dont?, my firefox installation is native at installing the dristro and having all perimission but it cant see my drives except the one is installed to (and where my OS is).

The only thing different i actually do is the folder where my current user info is saved, i moved the files from my user but with the files i had from my old windows session to impor my saved sites, favorites, etc.

Can you help me to be able to save files or images on my other drives?, thank you for time.

These 2 web sites worked fine last night.

Today ebay.com connects, but picutres on the site are blank spaces.

Gunbroker.com won't connect, it just sputters and sputters.

I entered these 2 sites on Chrome, they came up correctly. Gunbroker.com connected. Ebay came up with all the pictures on the site populated.

I have been trying to enable Firefox Sync on my Windows 11 PC (Firefox 145.02). I open the Firefox Sync window, I click on Log In, I enter my e-mail and click on "Sign up or Sign In" and then the view freezes and I never get any further. The attached screen capture never changes, no matter how long I wait.

My account won't sync my old passwords and browser history. I recently reinstalled windows and when I tried to sign in to my mozilla account my data wasn't there.

I can't figure out why gmail will not allow me to log in. It tells me that cookies are turned off but I can't even figure out what that means or how to correct it
