When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

Why won't Firefox open any new windows? I give ir the command to open a window and yet all i get are tabs and I never click on open a tab. I have an HP probook this for windows 10 and i am also having the same problem with Chrome. I have uninstalled and reinstalled chrome and that did not fix it so it is not that. What would cause this? I have already cleared the cache cookies history browsing etc. and nothing is fixing it. PLEASE HELP.

I have a lot of Firefox windows and tabs open, and I really don't want to lose my session.

I wanted to open a webpage in Firefox in fullscreen mode. But evidently there's some kind of serious flaw in Firefox that makes it incapable of opening webpages in fullscreen mode. Everyone says the only workaround is to open the webpage in kiosk mode. So I tried it.

But now I have two big problems:

1. One of my Firefox windows, with all its tabs, is stuck in kiosk mode. (Even if I close the window and then restore it with Ctrl+Shift+T, it's still in kiosk mode.)

2. All new Firefox windows I open with Ctrl+N are also stuck in kiosk mode.

I don't know what to do, and I'd really appreciate any help. Thanks!

I am running Firefox on Linux. Desktop environment is KDE. Compositor is Wayland. I have a 11th Gen Intel Tiger lake Core i3 with integrated Intel UHD Graphics GPU. I do not have a eGPU or any other GPU apart from the integrated Intel UHD Graphics GPU. Intel drivers are installed and are being used. Please see the details given below from about:support for more details. What I have observed that Hardware acceleration, specifically WEBRENDER_COMPOSITOR, WEBRENDER_SHADER_CACHE and WEBRENDER_DCOMP_PRESENT are disabled. The details are given below.

I have enabled the force hardware acceleration too by setting the property media.hardware-video-decoding.force-enabled to true. But still the above three hardware acceleration are still not available.

How can I get these enabled?

So I just noticed after downloading the new update to Firefox, version 139.0.1 that something new came up in my task manager called Crashhelper. Never seen this before. Closed it down and it seemed to have no issues shutting down at least. I haven't had Firefox crash in recent months, so I'm assuming that this cropping up might be a glitch of some kind? I looked this up to see if anyone else had this issue, and it seems someone on Reddit did encounter this, on Linux, and another on Windows also seems to have run into it. How do we stop this from coming up whenever we start up the browser?

To preface this, I am on MacOS.

I noticed a small delay before starting videos while I have my AirPods connected. There are a few scenarios where this delay does not exist: - Any other browser - Audio is actively playing elsewhere - Mic is in use (like a zoom meeting in the background, even when muted) - Audio is muted

I have tried safe-mode, reinstalling, and even messing with the config, to no avail. I know for sure this is isolated to Firefox, and I believe it's due to how audio devices are handled. I would rather my videos immediately play rather than wait for a "health" check from my connected device, even if there isn't audio for that time period.

As the question stated I have navigated to my mozilla profile folder, ( C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\pw1dnvcy.default-release ) but there is no file called persdict.dat. I have ensured all file name extensions are visible, & none are hidden in windows file explorer (Win 10). I am at al loss I cannot figure this out.

Hello, I just wiped windows and lost my bookmarks, passwords, and the like. I looked into the support options, as well Firefox profiles (about:profiles) but can't seem to get that data back. It's odd to me that it didn't sync because I also wiped windows last month and it recovered all of my data as soon as I signed into my Firefox account,so I was hoping that would happen again.

Any way to get this back?

Thank you.

When I go to view an already open tab it will sometimes randomly move it to the very end of my tabs all the way to the right. I don't want it to move tabs without my intervention. Clicking on a tab should keep it in place.

This has been an issue for about 2 months now. I'm not sure what's causing it or even if it's entirely a Firefox issue as I have noticed something similar happen in another program with tabs that I use often. It still seems like a Firefox issue in that moving a tab all the way to the end is a very specific task that can't normally be done accidentally.

Is there a way to prevent this from happening or has anyone figured it out?

This person has the same issue: https://connect.mozilla.org/t5/discussions/stop-reordering-my-tabs/td-p/93219

Firefox keeps crashing and Hanging and I get the error message "gah your tab etc" I have followed the advice for fixing the problem but it keeps coming back Its really annoying when you are trying to do something I'm no computer whiz and I have looked at the crash reports, its just gobble gook to me, I need help to fix the problem.

Hello, hope you're doing well So I deleted the app by accident, downloaded again , tried to sign in but I forgot the password so I reset it and signed in normally, however there's no bookmarks, no past history tabs, and most importantly no passwords, everything is gone, tried syncing multiple times but it didn't work.

Just updated to 139.0.1 and got a surprise. My New Tab Favorites Icons now have Push Pins in their upper left corners, leaving less space for the icons, so of course my icons are now smaller than before. Why do the people maintaining the system at Mozilla keep messing with the New Tabs? Last time, they thought they needed to include a large image of the Firefox icon, again shrinking the remaining screen real estate for my icons. That got fixed. Now they decided each favorite icon needs a rather large push pin to indicate that it belongs there. Somebody thought this would be a good idea? Why can't they just leave it alone?

I'm posting two screenshot images of my New Tab screen. You will know which is before and which is after.

For the past 2 days, Facebook won't load when I try to change my page to another (just switching between accounts). It acts like it is changing or loading, and then I just get nothing. I have done all of the things that are requested from clearing my cache, browsing data, restarting, etc. Nothing is working. I've attached a picture of my screen of I receive when I try to change pages - the big F. LOL Facebook on my phone works fine. I've tried also turning off my VPN and it doesn't load.

I've also had issues with my Xfinity email loading unless I turn off my VPN.

So what is going on?

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....
