Firefox Community Forum

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

Over the past 2 or 3 weeks, I've noticed that firefox tabs are crashing more often out of nowhere.

https://crash-stats.mozilla.org/report/index/4a42f4cd-2203-40ba-a40c-616590251210#tab-details

Here's one of the links for the most recent tab crash. Other crashes pretty much were all the same. I can't read or understand this, so I was hoping someone who can is able to tell me what is wrong.

I fear that it might be hardware related, as I've had tabs also crash on Edge and on a new install of Firefox Developer Edition (which I downloaded simply to test if things crashed there as well.) I've also noticed programs like Discord & Elgato Wave Link sometimes randomly crashing as well - but I'm unsure how to pull logs for those, Firefox was the easiest.

My laptop's hardware specs are as follows:

Lenovo Legion Pro 5 - 16IRX9 Processor: Intel Core i9-14900HX (2.2GHz) Installed RAM: 32 GB GPU: GeForce RTX 4070 Laptop GPU Windows 11

If you need more information, please let me know.

Here are some previous crashes that I've reported as well:

Maybe someone here is able to help me. Thanks in advance.

Hello. The browser will start fine and run for most of the day. I haven't made any known changes to the PC. At some point the browser will crash for all tabs and all windows. Any attempt to refresh goes to the screen as seen in the attached image. The "Restore This Tab" button does not work. I have to close all Firefox windows. Then the browser will work again.

I'm using an Alien computer. Windows 11. Everything is up to date. Firefox version 145.0.2 (64-bit)

Thank you.

TODAY'S (NEW-ish) ISSUE: - Multiple times per day I Click the Yellow button Top Left Bar to shrink and put App in dock to open again later. When I re-Large FireFox shows EMPTY FireFox Bar like I "Quit". Each time need to go to History and RE-OPEN ALL TABS??????

1. 2 within THIS text box just now, I highlighted the words: "Today's Issue" and clicked BOLD - instead it added a 2nd set of parenthesis???? WTF?

Browser is open all day. Always multiple tabs open/signed in, Paid & non-paid Apps, Email boxes, Wix, etc, many website tabs up, I do a lot of "research" - to pay my $rent and/or live my life using this "tool". Is my typical behavior. IN THE MIDDLE OF DOING WORK - I need to fix re-load Firefox again and again. . . Interrupted, distracted, observe, deal with so many Tech failures every day from ALL brands, I am struggling to keep my "life" functioning.

470+ issues/articles counted in the 11 subject boxes - in HELP section. FOUR HUNDRED-SEVENTY.

Thank you to "Volunteers" responding to help / issues!! Do you do any MENTAL help volunteering? kc

For whatever reason every time 'Firefox' browser goes down my email shuts down also. This did not happen prior to trashcan Win!!(recently installed). It's a pain in the ass having to reactivate 'Firefox' then contact my email server to reactivate my email service. Any assist is appreciated. TangoYankee in advance.

Since around version 96 it seemed some new core changes made to how ff operates. any one care to share what the "big changes" were around that version rollout tldr?

since ver 96 ff became secondary browser. Using to test/isolate issues w/chromium (sigh). Now since ver 132 profile manager opens browser for correct profile everything looks good then 20seconds later ff crashes eorror: Exiting due to channel error

Inspiringly i see this forum is being used still so thought i would see if anyone has ideas what changes btwn ver 96/101 and 132 which may cause this new issue, maybe i can backout the changes and get back to using ff as a secondary backup again ....

IDK about anyone else but i LOOOOONG for the ole days when ff was a daily driver option on linux

I'm in Troubleshoot mode, no extensions running, and tabs are crashing again. Here are crash report #s for today:

bp-68a25ce5-25e5-486f-8ac7-b1c440251204 bp-44d835db-c6b3-4fda-bc0a-2b3fd0251204 bp-456fdf26-e4ca-4994-a1a8-4fd960251204 bp-fd926c51-7db6-47b8-be27-28b340251204 bp-55c9f898-ec6a-4f5e-85d2-252900251204 bp-991e08b6-ff21-44e3-8cd3-2293a0251204 bp-3929ad82-3fed-439e-9877-1859e0251204

Is it coincidence that this is happening on my Windows 10 machine since MS support for Win10 officially stopped? Gosh, I just don't know! grar grar grar

Recently started having odd behavior from FF, crash sometimes when opening a video in PIP, crash every single time I open a new private window with hotkey.

Had some freezing as well as right-click menus not showing options, those went away by enabling HW acceleration.

Submitted crashlogs and found a bugzilla link refrenced. https://bugzilla.mozilla.org/show_bug.cgi?id=2000475

Can I downgrade to 144.0 without losing profiles/settings/passwords and history? Do I just download the 144.0 installer or is there a different process for downgrading? (I am assuming this could help exclusively based on the bugzilla refrence, it might not)

Not sure what else to do, FF is still freezing after watching videos for a few minutes, I am not even sure if this is strictly a FF issue or a Win 11 issue.

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

My computer glitched today. Before that I could bring up Firefox and all pages would restore.

Now Firefox comes up and shows one page like a new page. One tab and no other pages appear I had several open when the incident occurred.

Now I get the one page. From the Task Manager window I see the one page and "crashhelper" followed by several Firefox icons (all appearing to be using memory) but none of them are displaying any pages on my display.

I made a screen shot and enclosed below

My question is about lack of functionality (Topic) but it is not listed in the selections above!

I selected Accessibility because I cannot access any of the tasks shown below the "crashhelper" because none of these pages are displyed

At the moment all websites accessed through Firefox are all crashing after a few minutes and often a lot less. It is happenig constantly. It started before I updated Firefox today, but has continued after the update. Anyone know what's happening? I'm still on Windows 10 - will that be an issue?

Hello! I saw this question (below) on the forum. I'm having much the same problem. Firefox is crashing nearly all my tabs, even those that had been previously loaded. I cannot use it at all. Clicking "Restore this tab" does nothing. (Firefox has crashed tabs in the past but in those times, "Restore Tab" actually worked.) I actually had to write down on paper the subject and website of each of my tabs (and I had a lot of them, so this took a long time) because when I clicked on each already-loaded tab, Firefox would crash it and I'd lose it--and then it would crash the next one in line before I even got to it.

I have been using Firefox for years and it has never given me this much trouble. I've had tabs stored on it for a long time. "Restore session" always worked if I had to restart my computer for something. It does not work now because every tab crashes with the notice: "GAH! Your tab crashed. Click 'Restore tab' to restore your session." But "restore tab" simply crashes again.

Firefox has allowed a Masterpiece Theater tab and a link to my local newspaper, Pioneer Press (I have a subscription). Others crash. Even some Firefox pages have crashed!

After writing down the info for all my tabs, and then clicking on each one so it would crash and then deleting them so that Firefox had no tabs listed, I tried restarting my computer but this did not help. I also checked Malwarebytes, my anti-virus program, and didn't see a problem there (and I've had it for two years, always using Firefox with not much problem). I think I clicked on "update Firefox" recently and it seemed to work for a while after that, but now this.

I know a little about computers as a user but I'm not very savvy about repair or about all the different commands and controls. Trying to browse through all your articles to find how to fix the problem is exhausting, time consuming and leaves me really confused because I don't really know how to do the things each article suggests. I don't have the time to read article after article and still not be able to fix the problem.

Do I actually need to delete Firefox and then reinstall it? I'd lose all my tabs (website history is still showing under "History), stored passwords and stored credit card information and all other stored information. I'd have to start over completely.

I love Firefox and don't want to switch to Google or some other browser but I might have to if this continues.

According to your instruction to the user below--please be sure to view her note--here are some of my recent crash reports. Thank you for any help you can give me. Please also tell me how to reply to you if what you suggest does not work.

FYI, I have Windows 10.

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?"

the crash reports have been submitted 748057a7-6757-6eb2-955e-9602f9e91008

is there anything else I can do to get this looked into/resolved?
