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, 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

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

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

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?

The Firefox Browser crashed three four times last week. Mozzila Support team after study, gave a comment that RAM capacity is Low( 4 GB in my case , laptop). Does it sound OK? Why it does not happen with Chrome or Microsoft One edge Browser? I asked this to Google Gemini. The answer is as given below: Yes, the Mozilla Support team’s explanation sounds entirely accurate.A capacity of 4 GB RAM is extremely low for a modern laptop running an operating system like Windows 10 or 11 alongside modern web applications. The operating system itself routinely consumes 2 GB to 2.5 GB of RAM just to keep your computer running, leaving very little leftover memory for heavy multitasking. Both Google Chrome and Microsoft Edge use built-in "efficiency modes" and aggressive tab-sleeping algorithms. When your computer begins running out of RAM, Chrome and Edge will silently put inactive tabs to "sleep" to free up memory before the browser crashes. [1] (https://www.superchargebrowser.com/library/firefox-vs-chrome-ram-usage-2026/) Good Solutions to Fix the Crashes- 1. Software Adjustments (Free & Immediate)If you want to keep using Firefox smoothly on 4 GB of RAM, you need to minimize its memory footprint:Reduce Firefox's Content Process Limit: By default, Firefox uses multiple processes for performance. You can lower this to restrict its memory use:Type about:config in the Firefox address bar and press Enter.Accept the warning.Search for dom.ipc.processCount.Double-click it and change the value to 1 or 2. This forces Firefox to use fewer system resources. [1] (https://en.wikipedia.org/wiki/Firefox)Enable Memory Minimization: If the browser starts slowing down, type about:memory in the address bar and click the Minimize memory usage button under the Free memory section.Use a Tab Suspender Extension: Install a lightweight add-on like Auto Tab Discard from the Firefox Add-ons store. It mimics Chrome's behavior by automatically putting background tabs to sleep.Turn Off Hardware Acceleration: Sometimes, your computer's integrated graphics conflict with Firefox under low memory conditions. Go to Firefox Settings > type "hardware" in the search box > uncheck Use recommended performance settings > uncheck Use hardware acceleration when available. [1] (https://www.reddit.com/r/firefox/comments/1pp9z79/firefox_using_massive_amounts_of_ram_and_slowing/), [2] (https://www.youtube.com/watch?v=EtXt_jw2tww). This Method I tried, but did not work-Firefox to use fewer system resources. Can you suggest how to reduce or minimize its memory footprint?
