Hello, Since yesterday, the Firefox web browser crashes systematically. This has happened well over a dozen times. I've tried multiple step-by-step solutions: deactivating extensions, troubleshooting mode, repairing firefox, uninstalling and installing Firefox, trying several versions of Firefox (Quantum, ESR, Nightly), downgrading to an earlier version, uninstalling and completely cleaning Mozilla folders on AppData, deactivating graphics/hardware acceleration...

At one point, Firefox was crashing after ten seconds of watching a video on Youtube or another platform. After reinstallation, video playback no longer causes the browser to crash, but closing a tab does.

I am currently using Mozilla ESR 115.12.0. After reinstalling, I lost all the reports I sent. Nevertheless, I was able to reproduce the crash to give you the ID: [https://crash-stats.mozilla.org/repor.../a2d0f5de-d03f-450b-88f8-a8fdc0240705] Another crash report : [https://crash-stats.mozilla.org/repor.../71c602f6-c682-4158-9880-24d6a0240705]

According to the crash table, the reason for the crash is as follows: EXCEPTION_STACK_BUFFER_OVERRUN / FAST_FAIL_GUARD_ICALL_CHECK_FAILURE This reason appears on all crashes.

Thank you.

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Firefox on new laptop windows 11. (AMD Ryzen 7 5800HS with Radeon Graphics)

Have noticed only when i use Firefox i get intermittent flickering on the screen. It does not effect browsing, though it has frozen on a couple of occasions. I don't know if that is connected or just something else.

I have tried two trouble shoot 'fixes' i found whilst looking for a solution and neither have worked.

1 - turning off recommended performance settings and hardware acceleration. 1b - turning hardware acceleration back on.

2 - checking in troubleshoot mode to see if it's an extension. Flickering happened in troubleshoot mode too.

May I first say that trying to get hold of you to make this report was painful, and took about 20 minutes and a long walk around Mozilla's assorted website, opening two accounts, etc.

I received a notice while using Firefox on PC that an update was available. I was going to put it off, as I had 25 tabs open, but the notice indicated that my open tabs would be restored once the update was complete, so I approved the update. It download and I assume installed the update, seemed to temporarily close Firefox, and then reopened the original page with all my open tabs, plus an empty page. When I tried to open the tabs shown, they all indicated that the tab had crashed and then gave me the option of restoring that tab or on some restoring all tabs. Neither worked, in fact, that Firefox page became completely unresponsive and would not allow me to browse new urls (the tabs just spun). I actually had to use MS Edge to get to anywhere to seek out someplace to make a report. I first went to the discussion group and opened up an account there, but from there noticed that feedback on Firefox was at a different url. I then needed to create an account "here". Since nothing was working, I closed and reopened the Firefox page with all the tabs on it, figuring maybe it would restore the crashed tabs. It did not and all tabs were lost. I can probably get back to some of them using the history archive, but it was very disappointing and will be even more time consuming. I am running the current version of Win 10 pro, 64 bit, on a PC. I thought you would want to know about this. Thank you for your time.

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

When I go to google search on Firefox and search for something in images, every result loads instantly. When I go to duck duck go in firefox, there is randomly huge communication lag time between pressing enter and a result populating (usually more than 30seconds-2min where normally it is instant) and a good majority of the image thumbnail results do not display. It didn't used to do this and I think something screwed something up on my computer. What can cause this?

Things I have tried: Resetting Firefox Deleting and Reinstalling Firefox Deleting all cache/cookies/Mozilla files in %appdata, program files, and other locations and reinstalling.

I prefer to use DDG over Google. Can someone help? Why is it doing this?

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.

when i go to my amazon vendor central account i cannot access purchase orders. i get to a blank page that has this code on it:

'),t.close()}();

no idea what that is or why it is happening. then when i go to geminisound.com i keep seeing this in the top part of the website:

"); } else { win._boomrl = function() { bootstrap(); }; if (win.addEventListener) { win.addEventListener("load", win._boomrl, false); } else if (win.attachEvent) { win.attachEvent("onload", win._boomrl); } } doc.close(); } var link = document.createElement("link"); if (link.relList && typeof link.relList.supports === "function" && link.relList.supports("preload") && ("as" in link)) { window.BOOMR.snippetMethod = "p"; link.href = window.BOOMR.url; link.rel = "preload"; link.as = "script"; link.addEventListener("load", promote); link.addEventListener("error", function() { iframeLoader(true); }); setTimeout(function() { if (!promoted) { iframeLoader(true); } }, LOADER_TIMEOUT); BOOMR_lstart = new Date().getTime(); parentNode.appendChild(link); } else { iframeLoader(false); } function boomerangSaveLoadTime(e) { window.BOOMR_onload = (e && e.timeStamp) || new Date().getTime(); } if (window.addEventListener) { window.addEventListener("load", boomerangSaveLoadTime, false); } else if (window.attachEvent) { window.attachEvent("onload", boomerangSaveLoadTime); } if (document.addEventListener) { document.addEventListener("onBoomerangLoaded", function(e) { e.detail.BOOMR.init({ ResourceTiming: { enabled: true, trackedResourceTypes: ["script", "img", "css"] }, }); e.detail.BOOMR.t_end = new Date().getTime(); }); } else if (document.attachEvent) { document.attachEvent("onpropertychange", function(e) { if (!e) e=event; if (e.propertyName === "onBoomerangLoaded") { e.detail.BOOMR.init({ ResourceTiming: { enabled: true, trackedResourceTypes: ["script", "img", "css"] }, }); e.detail.BOOMR.t_end = new Date().getTime(); } }); } })();

please help.

I am trying to log on to my account at SketchUp. At the login page i hit get started and a black page come up except in the top left corner is typed "Firefox not responding" the page hangs a few moments then it takes me back to SketchUp login. I have not had any recent updates done or required since last logged in and that was yesterday all worked well.

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

I've been dealing with this issue for a long time now, without finding any solution

On macOS, whenever I am using Bluetooth headphones (Sony XM4, Airpods Pro), videos will hang for a few seconds just as the video is starting. This happens again if I pause/unpause or if I seek forward/backward on a video. The video "spinning animation" will appear and it will take 2-3 seconds for the video to start. This happens immediately, even if I click pause/start fast (ie: this is not after some delay necessarily). Also, if I mute audio on the video, the issue does not manifest itself.

During the waiting, Firefox itself seem to be hanging: for instance if I click on an extension icon in the toolbar, nothing will happen until the video finally start playing and then the extension menu will open up

When using Google Meet or Zoom for instance, I sometimes have to wait up to 10 seconds or so before Bluetooth Audio/Microphone starts after I've joined a meeting.

The issue is not specific to these platforms: I experience the same issue on other platforms such as Facebook, dailymotion, vimeo, zoom. On Facebook, since videos start muted, I can see the videos start playing right away, and then if I unmute sound the video stops, and start again with sound after 3 seconds or so

The issue does NOT manifest itself when playing an audio-only stream: ex Soundcloud or local radio stations audio stream

Things I've tried and didn't help - Troubleshoot mode - Different Firefox profile - Different Firefox install - Restarting my system

This feels like Firefox/macOS is waiting for Bluetooth to activate, or something like that. I have a feeling this only happens for certain types of video/audio codecs but I am not sure how to validate that (ex: no issues on soundcloud, petron audio-only posts).

The problem is entirely non-existent when I'm using sound output that is not Bluetooth.

This does not happen with other browsers otherwise I wouldn't be posting here :)

Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

Firefox Desktop issue,

McAfee malware has entered the Firefox browser a couple of days ago claiming viruses have been detected & requires me to click on their popup to remove it. Additional warning follow and reoccur every couple of minutes. I don’t have McAfee Anti-virus software on my computer & have not installed any new software for some time. The anti-software I have works fine (Spybot & Microsoft Security Essentials) and detects no problems. The first application I initiate upon boot-up each morning is Firefox and that’s when the problem begins. It is somehow related to Firefox. I cannot find any processes in play.

I’m using Windows 7 Pro

Sincerely, [removed email from support forum]

I tried all six free malware scanning programs suggested but nothing found

Hello,

Relevant system referenced below:

MacBook Pro 2021 Mac OS 14.5 Firefox 126.0.1 (64-bit) Carbon Copy Cloner 6.1.11 (7673)

I have a case of vanishing bookmarks. I quit Firefox last evening with command-Q as I’ve done a thousand times before. When I launched it this morning I was greeted with Firefox with an empty Bookmarks Toolbar and “Getting started” message. I opened a Manage Bookmarks window and everything there was empty too. I found, as well, that all of my saved UIDs and passwords were gone except for three, two of which I haven’t used in months. Weird.

Next I opened Firefox Help and found information about Troubleshooting Mode; I restarted in troubleshooting mode but nothing had changed. After restarting in normal mode, I tried Restoring Bookmarks; I chose Manage Bookmarks from the dropdown and then clicked the button in the Library window. Restore showed only one file and it was created today with only 14 items. Selecting Choose File… showed Desktop with Old Firefox Data highlighted. In that folder was only w34y3u9y…628 folder. From there I selected bookmarkbackups and the only file there was bookmarks-2024-06-06_11…lz4, a file created at 3:33 today. I found the key4.db file and it was created at 3:33 today.

I have Carbon Copy Cloner and use it for a weekly backup to a remote SSD drive. There are a year's-worth or so of weekly backups on that device. I tried trashing Firefox and reinstalling it from last week’s backup. While this worked, it didn’t solve the issue; it was still like a fresh copy of Firefox with no bookmarks.

I’m hopeful that I can restore the bulk of the lost bookmarks from CCC but I have no clue as to which files/folders to restore and I don’t want to guess. If you think this is possible, please tell me which files or folders to replace. Should I delete the files to be replaced from the current system and if so where are they located? I’m comfortable using Terminal for basic purposes but need explicit directions for entering commands and navigating to locations or files.

Thanks for your time,

David

Hello,

I am unable to either log in or access accounts on the websites indeed.com, x.com and chatgpt's openai.com

I used different computers (Windows 10 and Windows 11), different networks (Public library and private residence), and different versions of Firefox (125 and 126.0), one browser without any add ons and another with the "uBlock Origin" one, and I kept observing captcha or human authentication related errors.

With x.com, I would pass the human verification challenge (solve 10 puzzles), and then I would get the error "Something went wrong. Due to a technical issue, we couldn't complete this request. Please try again." I recorded my screen, and here you can see the video: https://web.archive.org/web/20240604035149/https://trello.com/1/cards/665e5d995d2e821054d66ac5/attachments/665e638096e76922e1404bd1/download/DISABLEMENT_-_unable_to_log_into_X_despite_passing_10_step_captcha_-_Screen_Recording_-_Made_with_FlexClip_-_20240603T172000PDT_-_shortened.mp4

Could I get some feedback?

Thanx

My Firefox has intermittently (but many times a day) been been slow loading, often simply refusing to load at all. Clicking a link to open in a new tab often opens the tab but the tab says "New Tab" with an oscillating dot on the left. After a few minutes the dot stops and nothing displays. Often clicking something in Google News the new tab says "Opening " and then the Google URL. The page sometimes displays after a couple of minutes but sometimes never does.

I've disabled all my plugins except LastPass, but that doesn't help. My IT Support company hasn't been able to help. I tweeted Firefox and they suggested I DM them. I've done that, even sending a couple of illustrative screen videos. But no oikne has ever responded to my Twitter DM.

Is there any way to talk to a live person and share my screen to get some help?

If not, I'll need to abandon Firefox as my default browser after many, many years. It's become a real productivity-killer.
