I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.

When I click the Firefox icon on my taskbar, it apparently starts OK, but in a second or so the window dims (See first attached image). This window doesn't allow any typed input anywhere, and doesn't close when I click the X in the upper left. This window can be made to go away either by using the Task Manager or by right-clicking on the taskbar icon and selecting Close Window.

However, if I right-click the taskbar icon and select Open New Window, the resulting window appears undimmed (Second attached image) and works correctly.

The above behavior is new; I've used Firefox for years with no problem.

The other user on this machine doesn't see this behavior at all.

I've been having an issue of, whenever I tab into Firefox from a different application on my computer, the alt menu opens. Firefox seems to be interpreting me opening the program as pressing the alt key, because even when I have the menu bar set to always be open, the input immediately goes to the "File" dropdown option of the menu, just as it would if I pressed the alt key. However, I tried to troubleshoot this by 1. opening a program that tracks keyboard inputs and that didn't show such a thing happening, and 2. I checked if this issue was happening with other applications that have switch the input to the upper menu bar when the alt key is pressed, and that was not the case. This is making it a lot harder to use Firefox, as using a keyboard shortcut to open a new window (ctrl+shift+p, or ctrl+i) while in a normal Firefox tab, it will not automatically open to the new window (as it is set to do automatically), it will also not let me open the new window -- either by alt-tabbing or by clicking the new window on the windows taskbar -- and instead reopens the alt menu and sets the input to that menu, locking me to the original Firefox page unless I tab into a completely different application and then into the new window. This issue also makes me unable to input key commands or text into my active tab immediately when I reopen it, instead forcing me to close the alt menu first either or clicking somewhere on the page. And since I don't keep the alt menu visible at all times, this forces the screen to shift up and down jarringly when I'm simply trying to use the computer.

I'm using Firefox on a Windows 11 computer. I've tried refreshing Firefox and have tried my absolute best to find articles related to this issue but to no luck. Thanks for any help or advice!

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

I use a Lenovo Legion 5 laptop pc and a second Samsung monitor. When the screens go to sleep with Firefox open on the second monitor, the second screen will not wake up again instantly. It can take up to 5 minutes or only after rebooting.

When I close the Firefox window on the second screen from the taskbar on the laptop, the second screen lights up again.

Win 11 PC laptop.

In background, it is using 40% to 50% of the laptop battery. I need much better performance from it. I have already turned off any settings I can find regarding Firefox's background functions. When I quit Firefox I want it completely off.

How can I do that?

I have a two monitor setup. Since I installed the new AMD driver (26.1.1), sometimes when I play a game on my main monitor, and watch stream on Twitch in Firefox on my second monitor, it can cause the PC to freeze completely. I hear the sound, but the image is stuck.

I tried to disable the hardware acceleration in Firefox, and it seemed like a good solution. But because of that (which is its function), sites became laggy.

Is this a Firefox, or an AMD issue? Or Windows (I'm on Windows 11 25H2)? I will try to install an older AMD driver, but honestly streams had became laggy before the driver update for me.

I have a problem with 'efficiency mode' in Windows 11. Windows 11 forcefully puts many of Firefox's tasks into efficiency mode marked by green leaves within task manager in processes tab. It doesn't seem to do this to anything else except Steam Client WebHelper. My Laptop is always in max performance mode in all possible settings as it is always plugged in (this does not influence efficiency mode). It slows down performance making things take longer to load and might even break them. If you try to enable efficiency mode on a task it even warns you of this: 'Efficiency mode will lower process priority and improve power efficiency but may cause instability for certain processes. Do you want to continue?' There is no way to permanently disable it. Currently out of 19 tasks 8 are in efficiency after I woke up my laptop from sleep (I have 5 tabs open). Only way to stop it is to manually disable each one by one (right click on each task and disable efficiency mode). But Windows 11 will turn them back on automatically usually within a few seconds (it seems to depend on opening new tabs, reloading them or waking up the PC from sleep mode). From looking it up online there seems to be a way to disable it in browser on Edge and Chrome but that might be something else (I do not use the so I'm not sure). There was a solution for Chrome but it doesn't work on Firefox.

Is there any way this can be disabled permanently through Firefox or Windows 11?
