Firefox Support Forum

Hello, the Firefox app often stops responding when I have multiple tabs open or when a more demanding process is running in a tab. Also, Firefox stops responding when I copy a screenshot. I have tried the browser without any extensions and the problem persists. I use EndeavourOS based on Arch linux, I use the current version of the system and Firefox.

Greetings and Regards In Windows 7 64-bit, when pasting in any of the empty spaces and entries, Firefox closes suddenly. Report ID 93d3828f-e08f-4b02-8f99-40070d9ac990 bp-b9584f4d-6683-452b-9fd5-5b46c0230527

for the past several months, FF has just been hanging when I attempt to open a website. sometimes it sits there for hours and never connects yet if I open Chrome, I have instant access. I have troubleshot, deleted and reinstalled FF, used safe mode to diagnose the problem. I have done everything I can think of, I even clear all history daily...and NOTHING helps. Sometimes I have no problems for weeks, then all of a sudden, I can't access the internet but ONLY with FF. I'm ready to just delete everything and never use FF again, but I like it and have been using it for 6 years. Chrome works 100% of the time....FF is hit or miss lately and I'm about done with it.

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Firefox in general uses a lot of CPU but when I watch youtube video in private window, the CPU usage goes to 100%. Why does it use so much CPU? I am using the latest version.

Hi Folk,

Firefox runs perfectly smooth in 3840x2160, so this is not a perf issue. However when switching from onboard laptop screen (2k) to my external WQHD screen, Firefox does not refresh, not reacting to input or mouse until I switch back and forth from another window. So it only refresh/repaint when main window looses and gets focus.

I have to restart firefox to make it works again.

Configuration: Linux debian stable (11) (same on PopOS) CPU: intel 8550 / GPU: Intel HD 620 RAM: 16Gb External monitor connected through usb-c 3.1

It does the same with Thunderbird. My Qt apps and terminals (alacritty) are not impacted.

The tabs are crashing. I can't use Firefox. I'm witting this on my phone. I don't know what to do. I tried to remove all the files of Firefox, but I can't, I need permission. Try to reinstall Firefox, I get the same thing. Nothing works.

Hello At the moment I is not able to log into an official Spanish WEB-site using Firefox version: 113.0.2 (64-bit) /Windows 11. I have sent the following question to the certificate issuer (accv.es):

I have a certificate issued by you which is verified OK. It works fine with:

https://sede.agenciatributaria.gob.es

https://www.suma.es

but with dgt: https://sede.dgt.gob.es/es/ I get this message when trying to log in to 'mi DGT': XML Parsing Error: no root element found Location: https://sede.dgt.gob.es/es/mi_dgt/index.shtml Line Number 1, Column 1: Can you help find the solution to the problem.? I can not find a DGT-contact to ask for help Best regards Morten Brinch

Accv.es have so far not given me any clues to what I can do.

Anyone having suggestions how to fix the problem ?

best regards Morten Brinch

Dear Firefox Support Team,

I am writing to report a problem that I have encountered while using Firefox browser. Specifically, I have noticed that the CSS property grid-template-columns: repeat(auto-fit, minmax(120px, 60px)) does not seem to work as expected in Firefox. The grid items overflow the container and do not adjust to the available space.

I have also tested the same code in Google Chrome and it works properly without any issues. This indicates that the problem is specific to Firefox and related to the lack of support for the auto-fit & minmax value in the repeatfunction. Therefore, I kindly request that you investigate this issue and provide a solution or workaround that would allow me to use the auto-fit value in Firefox.

Thank you for your attention to this matter.

Sincerely, Yoosef Alipour

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

Not sure if its right topical, but when doing stuff online that include javascript, occasionaly when it will give the error 'Error: TypeError: WebGL2RenderingContext.texImage2D: Argument 9 can't be an ArrayBuffer or an ArrayBufferView larger than 2 GB (see JavaScript console for details)', is there a way to give it more or is it script specific? Cant find any help on the forums out there so hoping this will help

Thanks

Suddenly i keep getting this error code. After trying things like refreshing Firefox, using No Proxy option and still getting this error. I dont know what to do, except for changing the browser.

Hello,

Since some days I can't upload or download anything using Firefox. Right-click on an image and click "download" - nothing happens. Right-click on a web page and click "Save Page as" - nothing happens. Try to upload a file to DropBox or Google Drive - no popup appears, no error message, no response whatsoever. Opening the downloads list in the browser and trying to open the folders where I had previously downloaded things (when downloading was still working) also has no effect - the folder does not open on the desktop.

So apparently the problem is some kind of broken interaction between Firefox and Ubuntu (Nautilus?)

Downloading and uploading works normally with wget and Chromium.

Steps already tried: - Resetting all browser data - Refreshing the browser - Activating troubleshooting mode

Firefox: 113.0.1 Snap canonical-002 1.0 Ubuntu 22.04.2 LTS

I just followed prompts to load new Firefox. I can use open tabs but cannot go anyplace new without the tab crashing. I am writing this from Microsoft Edge! I have Windows 10 and see nothing about an S version so assume I don't have it on. I have had little problem with Firefox for years until now. Am not a techie and am in my 70's. Help!

I have started having with receiving the message "We can’t connect to the server at". This is really bad as I do a search and then can not reach the sight.

Thanks Dicky Sheehan

Firefox is completely non-functioning. My home page won't load, animations don't work, downloads don't work, menu buttons don't work, and most pages display blank. I tried booting in safe mode to refresh, and restarted my computer, both to no avail.
