Forum communautaire Firefox

So, similar to this post but I haven't downgraded, only upgraded.

OS: Windows 11 (26100.8893) Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:153.0) Gecko/20100101 Firefox/153.0

I can load it up in the morning, load all my standard tabs, then not too long into it a tab will 'crash' and require a reload. The reload then says its a dramatic crash and the whole browser needs to restart. Soft or Hard (i.e. "Exit") restarts always then ask to create a new profile on startup. This means I lose so much configuration (settings, etc) that is not in the Account Sync, meaning huge amounts of time have been wasted setting Firefox back up again every day.

When I go to about:profiles I can see all the old and new profiles (recently cleaned up all the old ones).

I do use my FF Account across various versions of Firefox (run a linux OS that still has a 14x version - need to upgrade OS to get more recent, but its a significant upgrade that had previously failed so not high on my 'want to resolve' list) - all the Windows OS's have the latest FF.

Some pages keep crashing and need to be restored. Even if I open new tabs, once I get to them most of the time they have crashed and need to reloaded too. Even after reloading they will continue to crash. This after Firefox's latest update.

Hello,

I have been unable to update Firefox past 132.0.2; every time I download an update and install/restart, all tabs automatically crash upon loading regardless of the website. I can load local pages like settings or about:config, but anything that actually uses the internet goes straight to crashing (including sites as simple as google.com). I have tried restarting in Troubleshooting mode to no avail. There are no crash reports when I pull up about:crashes, so unable to post IDs here.

It is not an internet access problem (I am [unfortunately] filling out this form from Edge), and with reversion to 132.0.2 everything moves along hunky-dory. I am also able to use the newest version of Firefox on all of my work devices, so it appears to be something in particular with my person PC. Problem occurred with both Windows 10 and Windows 11.

Any help would be much appreciated- I didn't mind an older version of Firefox that worked, but there have been some MFA logons that refuse to go load in v132 so it's becoming something I'm less able to ignore now. TIA

Hello, hope your day is good. Since the internet wide announced date in mid June ;; where Microsoft made bios changes which blocked 3rd party vendors programs from fully connecting ,,, my laptop has not been able to ( run) Firefox ,, with out problems . Even to point where my laptop,, locks up . This summer of 2026 has been the worst computer stability issues ever. I’ve been forced to constantly hard stop my rig , spend hours with rebooting ,, and then using Revo to delete non MS apps ,, then download apps ,, especially FireFox Is there a permanent fix to get around the deranged tyrants at MS . Thank you

The Firefox window closes after uploading a file to a hosting site In fact Firefox is not completely closed. I just need to click the Firefox icon in the taskbar to open the window again. it's not a big deal but it's still annoying.

Mozilla Firefox keeps crashing repeatedly while I am searching or typing, and the problem persists. Why is this happening, and what is the solution? I request you to investigate and fix this crashing issue as soon as possible.

Hello all, thank you in advance for your time. I've got a Lenovo running Linux (Zorin, an Ubuntu branch)

Crashes have been more and more frequent over the last couple weeks. Usually it closes only Firefox, sometimes it throws me back to the login screen, and rarely the computer crashes entirely. I've been trying to pin down the source of the crashes -- it hasn't only been Firefox, but most of the crashes are while FF is open.

THIS tab keeps crashing, as I type.

It seems to happen more often when I'm watching video.

Here are all the crash IDs within the last 24 hours: bp-dfb0bd40-4ce6-41bd-b9cb-ad0510260913 13/09/2026, 11:15 View bp-50a8400a-3439-4af4-b5c7-6e60f0260913 13/09/2026, 11:15 View bp-0893e979-6a06-40cc-ad0b-757210260913 13/09/2026, 11:15 View bp-8a1bbc36-9c1d-412c-a2cf-c4c040260913 13/09/2026, 11:15 View bp-4c97e699-dee7-470f-9f82-855760260913 13/09/2026, 11:15 View bp-4526b2af-908a-45be-89ae-293ef0260913 13/09/2026, 11:08 View bp-60af27d7-aeef-4761-b86e-7595a0260913 13/09/2026, 11:08 View bp-25b42dd1-3f54-4be4-bde7-801f60260913 13/09/2026, 11:08 View bp-e92ad4f9-b7d3-453e-8c5a-066910260913 13/09/2026, 11:08 View bp-d19f0c4c-9eb7-45d1-a7e7-978d90260913 13/09/2026, 11:08 View bp-b212719f-1daa-459c-8491-2c6cb0260913 13/09/2026, 11:08 View bp-9effc3ad-0b73-43d2-839c-805a00260913 13/09/2026, 11:08 View bp-7e5b6de1-7a84-48ad-86c0-e07510260913 13/09/2026, 11:08 View bp-271c4c4f-9f81-480a-9815-5f5bf0260913 13/09/2026, 11:08 View bp-956cef3e-25a1-4a8c-b7e1-668be0260913 13/09/2026, 11:08 View bp-92a596e6-edc8-4920-9365-6e3e00260913 13/09/2026, 11:08 View bp-6e309137-bf0a-4ee1-8ddf-492b20260913 13/09/2026, 11:08 View bp-d3eadcae-1967-4c31-856f-284f80260913 13/09/2026, 11:08 View bp-e319008d-d7e3-4354-95db-846e10260913 13/09/2026, 11:08 View bp-ce80cf98-4aad-46ee-a2a2-40ccf0260913 13/09/2026, 11:08 View bp-41734b4e-09d0-4dfe-ab7a-c74400260913 13/09/2026, 11:08 View bp-37752c09-a2ae-4f35-8ee6-62ee60260913 13/09/2026, 11:08 View bp-01aed5a5-d3da-4551-9646-eb73d0260913 13/09/2026, 11:08 View bp-0d52d173-f46d-4d5c-b723-441930260913 13/09/2026, 11:08 View bp-5a9507dd-21f3-4be3-8d68-ad70f0260913 13/09/2026, 11:08 View bp-0a5b5b7c-6400-41f7-ba67-c881b0260913 13/09/2026, 11:08 View bp-2ff2f687-e231-4ac5-925a-fde060260913 13/09/2026, 11:08 View bp-1c9a1836-3ebe-40bd-ac76-182850260913 13/09/2026, 11:08 View bp-f4bbc332-be5c-48f7-8e6e-c008a0260913 13/09/2026, 11:08 View bp-807e438c-9bb1-4056-b67b-48e870260913 13/09/2026, 11:08 View bp-b422a84c-4096-4ab8-926c-d63030260913 13/09/2026, 11:08 View bp-9740f00f-a1ac-4fce-96b3-704940260913 13/09/2026, 11:08 View bp-0a571a75-602f-4802-98df-22ee30260913 13/09/2026, 11:08 View bp-5f7a41ac-f92a-42b3-96bc-6dda70260913 13/09/2026, 11:08 View bp-d81a88f6-3da4-4e15-8669-352390260913 13/09/2026, 11:08 View bp-324a6102-496b-4724-9deb-3532f0260913 13/09/2026, 11:08 View bp-40969791-0669-4158-abd6-b57230260913 13/09/2026, 11:08 View bp-7b5c8e37-6cfe-4027-9bd1-fc0d80260913 13/09/2026, 11:08 View bp-62dbac62-1feb-47a6-be53-bd8b10260913 13/09/2026, 11:08 View bp-9197029c-0719-4294-bc37-e7f320260913 13/09/2026, 11:08 View bp-941d7f54-5b2e-4783-83f2-66c330260913 13/09/2026, 11:08 View bp-00202476-8680-4295-8a76-a97db0260913 13/09/2026, 11:08 View bp-027dfa8e-f3e1-44e9-a405-1ae350260913 13/09/2026, 11:08 View bp-369f58c9-4456-4578-977e-49cfe0260913 13/09/2026, 11:08 View bp-78c25147-3a9c-4ad8-9210-eb0ca0260913 13/09/2026, 11:07 View bp-f1f4b2b3-0885-4259-8dd3-bfa700260913 13/09/2026, 11:07 View bp-72d20621-92ea-417a-b063-deba40260913 13/09/2026, 11:07 View bp-721a4c72-ab3c-4ea0-8428-72b6d0260913 13/09/2026, 11:07 View bp-ffb02689-cb96-48e2-ab89-1c7f10260913 13/09/2026, 11:07 View bp-407b7ac2-8d4c-404d-974a-96d790260912 13/09/2026, 0:37 View bp-9decd8ef-b380-4bfe-8264-6841b0260911 11/09/2026, 22:40 View bp-c9a8eae8-8723-48ba-aab0-48db10260908 08/09/2026, 22:57 View bp-e0ac525c-a6c7-4af5-abe8-0ab5e0260913 13/09/2026, 11:16 View bp-91be494d-2e41-42b7-9330-e49630260913

Recently I cannot use Paypal to process any online payment on Firefox without the browser crashing.

OS: Windows 11 25H2 Reproduction steps: a vendor would have a Paypal button. I would click on it and Firefox would open a pop-up window briefly before crashing.

The pop-up window is normal behaviour for how Paypal processing has worked on Firefox in the past. I have tried turning off potential content blockers: 3rd-party userscripts loading through ViolentMonkey, content blockers via AdNaseaum, and Enhanced Tracking Protection to no effect.

I tried updating Firefox or testing for the crash in Troubleshoot Mode, but it keeps crashing every minutes or so. Here is the report ID bp-67065b07-74d6-417e-b7de-caf500260906

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

Firefox has recently started turning itself off. There is a failure message and it self-reports the issue. However it will do this without any website loaded, it just fails to continue running without a website being loaded. This happens everyday. The application will not continue to run just by being an open application with an empty about:newtab This is very frustrating.

I see this in abrt:

Is this normal behavior for Firerfox 155.0 on Fedora 44 KDE-Plasma 6.7?
