The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?

Hello,

I tried to use the Cascade window feature on Firefox but its not working, other applications are working fine, I have attached * Screenshot of error* Raw Data and Text. I did not try to check when i installed first but its not working now. I also have not reinstalled it yet.

Please help and thank you. Best Regards, Alootikki

Hello,

After recent macOS updates, it appears that Firefox would get stuck when trying to access passkeys stored in macOS's passwords or keychain apps. I run into this issue with both the following two combinations of Firefox versions and macOS

144.0.2 on macOS 26.0 Tahoe

140.4.0esr (aarch64) on macOS 15.7 Sequoia

Any insight is appreciated!

I usually have multiple tabs open and my MacBook slows down and gets hot. Firefox is using A LOT of memory. Is there a way to have inactive tabs go dormant, helping reduce overall memory usage and improve browser performance? An advisor mentioned this is an option in Chrome. Is there a fix?

Thanks

After I disabled ws2ifsl in the Registry Editor, problems began to occur when launching Firefox: as soon as I clicked the mouse after starting Firefox, it would become unresponsive. Even re-enabling ws2ifsl or refreshing Firefox was of no avail. No matter what I did, it would enter a completely unresponsive state as soon as I clicked the mouse. Do I really have to reinstall Firefox? Note: This is for the Windows version.

Recently I have been issues with switching between windows of Firefox. No matter how many times I try to Alt-Tab or click on another window it momentarily goes to that window before switching back immediately. The only work around I found is to click a window of some other software and then click the window I want to work on in Firefox. Doing this is not making it switch back to the older window of Firefox again. Please help me in fixing this issue. It's making it nearly impossible to work on Firefox due to this.

For the past few months, I have had a problem with my computer - it seems to try to write to a hard disk (sounds like whirring ) and the keyboard freezes up for a few minutes, when whirring in the computer stops. I have taken the computer to Geek Squad two times and they said they found it, but it still happens.

I have just tried Google Chrome and Microsoft Edge and I haven't noticed it. Is this a problem with Firefox or just coincidence?

Hi! I have extension and user scripts and such. I can make memory reports, but I can't determine anything since there's too much stuff in there that I don't know anything about. Is there a tool to help me point out issues, or is there by chance people looking at memory reports like this on occasion? The reports themselves are 80-100MB within the .gz files. Which are compressed to 5-6MB. Not sure if full are necessary or anonymized reports are enough. Not sure what sensitive info they may contain.

Hello,

I am having an issue where my menu bar continuously shows up. If I create another tab and drag it to create a new window, it goes behind my active window. When I try to change to that window it continuously opens the menu bar and refuses to allow me to change. I have to minimize my current window and drag the other window to get it to focus. Alt + Tab does not work to swap between them. Every time I click an application and click back to window the menu bar appears again, sometimes I have to click 3-4 times before it goes away.

I have tried made sure it was not my keyboard with an alt key stuck, tried multiple browsers, only firefox is the issue. I've created a new profile with zero extensions, the issue persists. I've also completely refreshed firefox with no success. Made sure all my drivers were updated and restarted the PC, unhooked the keyboard, nothing works - it continues to have issues. Running out of ideas here. I've also tried the below below solution for the menu bar and again, no luck. Any help would be great. Thanks!

The attempted menu bar fix I've tried:

Type about:config into the address bar and press Enter. Click "Accept the Risk and Continue". In the search bar, type ui.key.menuAccessKeyFocuses. Double-click the entry to change the value from true to false. Restart Firefox.

HI, sorry my English is not so good -hope, you understand me. Since a few weeks I have a problem with firefox: after using the browser without any problem, I close my Laptop by dialing "Ruhezustand / hibernation". When I open my laptop again (regardless of duration), Firefox tabs are "grey", cannot be longer used. I have to close the browser completely and start again, very cumbersom! What can be the problem? IOS is updated, Firefox also. No other browsers have this problem. Hope you can help me? Best regards

There is a bug which was reported 3 month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1959157. It appeared out of nowhere and I don't even know if it was fixed since then. But it is bugging me a lot, no pun intended. Any help would be appreciated.

Sometimes, when I have multiple windows open, closing a window won't completely close. It leaves a blank area where it was, the title of the window is displayed, but clicking in the area just switches to one of the other open windows, and there seems to be no way to finish the process. This has been a problem through the last few Firefox updates. Any thoughts? OS -- macOS Tahoe 26.1 Firefox -- 145.0 (aarch64)

Can i reinstall firefox but keep all of my settings, history, bookmarks, etc

I tried to open a Thuderbird email in Firefox (long story) and its going crazy! Just opening it, opening it, opening it..... just doesn't stop! Help! What do I do?

As this happened just after the update today I think there must be a.problem with the update so therefore you need to supply a fix ASAP As I have said I am unable to access any menus so no access to account setting, cookies, new bookmarks, this only appears to be affecting Firefox on PC's, as I opened this tab on my phone

I just got the profiles update and I'm having a lot of issues with firefox, but I'm not sure what I did wrong. When I change windows both too and from firefox, the menu pops up. As I continue to use it, my controls slowly begin to change. My scroll wheel changed from moving up and down the page to the same command that happens when you go backwards or forwards using the buttons in the top left. I lose the ability to use the windows key on my keyboard. Eventually, I lose the ability to type entirely sometimes, so all the keys from the keyboard just stop working, even though it's plugged in and recognized. Also, if I have firefox open for too long in the background, I'm unable to tab out of whatever window I'm presently in, even if firefox is just running in the background.

I've isolated the problem to just firefox by using other browsers like edge and chrome. While having both of these programs on in the background or during regular use I saw no issues with my pc.

I've tried the main trouble shooting steps provided by firefox, but none have helped. I also thought maybe some of the extensions were causing problems so I stopped using all the ones not from firefox directly, but this also didn't help. I still have the container extensions on.

I think I'm on the latest necessary windows 11 update, but maybe need to go to 25h2? I'm just guessing at this point.

What am I doing wrong with the new update and how do I use the profiles properly so I don't have these issues?
