Firefox Support Forum

I prefer using Firefox as my browser (have done so for years), but recently I have noticed inability to open some hints provided on my family trees on Ancestry.com

When I called Ancestry, they suggested I use a different browser (: - but when I did, I was able to open the hints Firefox won't open. What is the problem? I was also told that another Ancestry user had called in previously with the same problem. PLEASE fix this!

If it helps, I use Windows on an HP Envy laptop (have for some time - wasn't a problem before a month or so ago). Will I hear back from anyone as to when this might be addressed/fixed?

My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Everytime i try to watch a video it says it can't play or it just sits there buffering. Youtube works but only lower quality, but every other site i go on doesn't. Twitch won't load, other sites show Error Code: 102630. This is only a problem on my browser on my windows pc I have. On mobile the browser works great and has no problem showing videos so it a problem for my pc browser.. I've tried all of the steps, i've updated, i checked drm and even went into config to check there. But nothing works, it still can't load videos. I have version 125.0.3 and for me it's the latest one. I even turned off all of my add-ons to check if it works or not but nothing there either. It worked before, just now the latest two months it hasn't. What can I do in order for the videos to load? Thank you for your time.

I've had this issue ever since switching to a new laptop. This issue is specifically within Firefox (I have tested this in other browsers and programs, and the issue isn't there. Everything else works perfectly fine!)

Essentially, whenever Firefox plays multiple sounds at the same time (for example, I use both youtube and discord in-browser) the second sound will briefly mute the other sound. (Going back to the discord-youtube example, if I am watching a youtube video and recieve a discord notification, the youtube video will pause for about half a second.) Or if a site has background audio but also plays a short audio clip when certain elements are clicked, for example, it will cause this "overlapping" issue. Again, this issue is only within Firefox.

I am using Windows 11 if that helps. I've already tried using a Firefox Refresh and peeking in about:config but I'm totally lost as to what I can try next, since I can't find any other examples of people with this issue online. Sometimes the issue briefly fixes itself but then reappears.

I've reported these issues before with no response. I've uninstalled reinstalled cleared cache and cookies searched another forums et cetera. Why must I manually update when it's set to auto update? When I set controls to ask where to download items it bypasses that and downloads it as a temp file where I have to cut it out of explorer and paste it where I would like to save it.

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!

Starting today (Apr 30), when trying to open firefox the following message appears:

"Firefox is running, but not responding. The old Firefox process must be closed to open a new window." My options are to close firefox or cancel.

When selecting close firefox, the message will reappear with the same options. I am unable to run.

Steps I have taken: Uninstall Firefox Download latest Install

Message still appears

I am able to start FF with no problem. I open a few tabs and then without warning I can't access any of the sites without closing FF and restarting. Then the whole cycle is repeated. I am considering getting rid of FF this started just over a month ago.

WHY IT LOGGED OUT ALL MY ACCOUNTS FROM TABS WHEN EVER I CLOSE MY BROWSER, I HAVE TO RE-LOGIN AGAIN AND AGAIN, WHICH IS SO SO FRUSTRATING..................................

Hello! I've recently switched to Firefox from Opera. However: After the browser Closes, It will always Refuse to boot up. Even Shift-Click Doesn't work. It opens, but Crashes almost Instantly. OS: Windows 11 (Build 23H2)

I am tired of this [removed] browser quitting, even when I don't have it open...I am going to uninstall it and NEVER install it again...I tried a full uninstall to see if it would fix whatever the [removed] issue with it was, but it is doing the same [removed] again!...I don't have this problem with any other browser I use on my system (Chrome, Brave, Opera and Tor)...I am tired of dealing with this [removed], so you can just take your [removed] and shove it!!!

How the hell does a browser crash when it isn't even being used???!!!

No need to respond and ask for any logs or other [removed], because it will all be gone!!!

Hello,

My name is Grey, and I'm experiencing an issue using Firefox as a browser to open my Outlook mail. For the past three days I have not been able to open any emails as a network error screen appears. Using other devices and other browsers like Edge, the emails open fine, so it is not actually a network issue. This problem only occurs using Firefox, and specifically with Outlook emails. Everything else functions fine and I have not made any changes, besides the regular Firefox update. My computer is also up to date.

What can I do about this issue? I appreciate the advice,

grey

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

I'm trying to watch videos on Disney plus and Amazon prime. I can't get them to work. I tried various tutorials but many were irrelevant because they referred to google chrome which I don't even have. I tried checking and unchecking the enable DRM checkbox. Widevine never seems to update. I do not know how to install in manually.
