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 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.

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?

Just recently I am no longer able to login to the discover.com site in private mode. It still works in regular mode. I'm using this on a desktop, not the discover app. I spoke to their tech support and tried to do a login while on the phone. They told me nothing was coming through on their end. So, what changed and how can I fix it please?

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

Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

Hello,all, The built-in translation button in Firefox disappeared on the Reddit website.

Please add a fixed access key for the 'Translate button'. I also recommend introducing an automatic website translation function. Thank!

Hello everyone. From a while now that I need to change to Google Chrome everytime I want to put my credit card details to buy something online. Simply because the text boxes in Firefox don't show. They're simply not there. There are very few websites where they show up for half a second and disappear right after. I've tried disabling "enhanced tracking protection", disabling all my plug-ins, changing the "hardware performance" option, cleaning cache and cookies. Nothing seems to work. I'm going crazy because I like firefox and I want to work always in this one browser, not changing each time I want to do a different task. Similar thing happens with some websites when they freeze before you explore them and the pop-up window comes asking you about the cookies. But some of these, the window disappears right away, so I can see the page but it's stuck, because I didn't manage to accept the cookies option

Please, can you advise me what can I do? It's getting very frustrating, I'm really considering moving everything to Chrome and I don't want to. Thank you.

Bellow you see an example of Firefox page and Chrome.

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

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

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

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?????

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.

The 2-year-old support page "View synced tabs from other devices" gives 2 methods for syncing all your tabs from one Windoze FF to another. Neither one does anything at all for me now. The "right-click on the device in the sidebar" sounded SO promising, but it does not cause anything at all to happen. And checking the "sync tabs" box does indeed make them all show up in the sidebar list, but does not open anything. So besides clicking on each of the hundreds of tabs listed, how can I do this, or is it just another FF functionality lost to time?
