Whether a person clicks the fullscreen indicator or types F on the keyboard, the cursor will remain on screen as the video is playing until it is again moved. This also affects video played through the browser on steampowered.com. This issue appeared as of 143 and is still going strong in 144. This seems to be macOS specific as I am not noticing this behaviour on the Windows client. Could be a conflict with Tahoe.. I don't really know at this point.

There used to be a website where you could fire off a 'Firefox made me happy/sad' which is where I would've preferred to send this. So, have other people encountered this issue? And if so, are there any lasting solutions beyond wiggling the mouse?

I am having difficulty using Google Sheets within Firefox Developer Edition 144.0b4 (64-bit) on Linux Mint 22.2 Cinnamon. When I load any of my Google Sheets, I am unable to scroll. This includes when using a blank sheet.

I also have Firefox 143.0.1, which seems to still be functioning correctly.

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

I have Firefox installed on both my desktop and my laptop. On my laptop, I am able to create and manage profiles; however, on my desktop, there is no option available in the menu (the hamburger menu) to do so.

I have verified that both devices are running the latest version of Firefox, which includes the profile management feature, but I am still unable to access it on my desktop.

I have clear search history when browser is closed checked, and it still has a months worth of history and I have closed and reopened the browser countless times, why doesn't the history clear?

I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

This is the 4th time I've reported this problem. Here's the warning I get every day only after I have already been loading Newsmax pages with no problems:

Secure Connection Failed

The connection to www.newsmax.com was interrupted while the page was loading.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

There are no other sites in which I have this problem with FF x64 DE. In Edge, I see the newsmax pages load while the FF x64 DE https//newsmax.com xontinues to genberate the above message and fails to load the screen.

Please fix.

Thanks, WaltC

My version of Firefox wont save History, Bookmarks or Downloads. I've made sure the privacy settings are correct and have tried reinstalling Firefox several times. It also wont let me drag a link from the address bar to the bookmark bar anymore like it used to. Any help with this would be much appreciated... Thanks!

I noticed recently that my 'Add Shortcut' button has disappeared. I've been through other articles and they were of no help. I have 4 rows selected for shortcuts so theres no reason for it to be gone.

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

I had two Firefox windows on my computer, one with a few tabs of Youtube and Twitch pages, and a private window with a single Twitch stream. I've had them and the program open for days, with my conputer turned on and off multiple times with no issues.

Today I booted a game I installed yesterday on my computer and played for a few hours, after closing the game, both my Firefox windows became completely inaccessible.

I've tried closing firefox, restarting my computer, letting Firefox create a new xulstore file and nothing has worked. I can't see the window, I can't make it active. It's permanently minimised.

It spikes Desktops Windows Manager to 100% GPU usage, it makes my PC lag and run slow, and I can't do anything in the browser cause the window won't stay open or up. I can't even open the old window and then a new one, it stays minimised and I can only see the preview by hovering my mouse over it.

I've tried GPU driver updates, I tried anti virus scanning, and I've tried opening another browser which did work. But Firefox is the one with all my saved settings and preferred browser. I also can't see the Firefox window at all when using the window key + TAB to check my desktop, but it does show up on Task Manager as running.

Please help me restore my program. I'm making this on my phones firefox browser which is running fine

Something very bad happened to me today (11/3)....

Firefox 144.0.2 was installed on 10/30/25, and everything has been fine until today. I don't know why or how, but ALL of my OPEN tabs (of which I have many--and have it fixed so they always re-open when Firefox starts), ALL went away.

In reading conventional steps to recover such from sessionstore-backups, those instructions sounded straightforward. However, even though ALL FIREFOX PROCESSES were ended, I could not copy the contents of the sessionstore-backups folder nor could I delete anything--EVEN THOUGH I am the owner.

Even after providing Admin perms.

I could get rid of profiles.ini, which initially proved diasterous, because then Firefox thought I was brand new, so ALL of my passwords saved through Firefox these many years, went "poof".

Fortunately, I was able to get that back, but I still cannot get all of my tabs back, and conventional instructions to do so aren't working.

After recovering from my heart attack for initially losing my passwords, I am breathing a little better right now, but it sure would be nice to get all of my open tabs back again. I don't know why I am not able to manipulate the files within sessionstore-backups. I think if I could eliminate the files in that folder EXCEPT for upgrade.jsonlz4-20251027123126, which possesses a 10/29/25 date, these should be the open tabs just before the 144.0.2 installation, and all should be right with the world, once more.

I have performed/examined many steps offered under this category, but most assume I can copy them elsewhere for safe-keeping and/or removing all but the one I want Firefox to "use". Because something is preventing me from doing this, though, I am being stymied in what ought to be the solution. As a test, I was able to copy files from a much older profile--so I can prove the basic steps SHOULD HAVE worked. Unfortunately, I cannot do the same with THE (more recent) folder in question. I can't get rid of parent.lock, either (and I have ensured no Firefox processes are running via Task Manager).

Repeatedly.

Something else is at work, here. Any help or assistance from community experts would be most helpful.

Thanks very much in advance.

I keep getting 'notifications' from Mozilla Firefox that McAfee has discovered a virus, Trojan, and other things. They come on the lower right corner of my screen and the address d3mj6kghubcc73dtudhg.kaironero.co.in is along the bottom of the notification. The notifications pop up every time I turn on my computer and go into Firefox and they just keep coming after I dismiss them. They are in small rectangles and have Mozilla Firefox written across the top left and say that McAfee has discovered.... Are they legit or are they spam and how do I stop them? I don't have McAfee installed on my computer which is a desktop. Please help--this is driving me crazy!!!
