Firefox Support Forum

Hi all

I'm a happy user of FF but have started to see issues with JavaScript (error message: You need to enable JavaScript to run this app.). I do the about:config correction and it sometimes works, but now the error is spreading to involve other pages - a page worked yesterday doesn't work today.

Is it just me?

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?

Firefox recently stopped playing embedded youtube videos on my phpBB forum site?

i keep the latest firefox and only recently showed up embedded videos play fine on Chrome and others

here's a link to my forum which includes an embedded Youtube video demonstrating the issue, does it play on your browser? (ONLY firefox has an issue on my computer, chrome, etc. work fine)

thanks for any tests/insight into what might be causing the issue

Hello,

I reinstall my windows 11 yesterday and since I cannot log in office. I go through the identification process, then once done I am back to the sign in page.

On chatGPT, when I go to login, I got the error message "We ran into an issue while signing you in, please take a break and try again soon."

Both websites were working fine last week. Also on the same computer I can access these websites using chrome. I tried to clear the cache and the cookies, disable extensions (ublock + cuberghotVPN), lowering security options like disable DNS security and disable tracking security, I uninstalled and reinstalled firefox, but I can't fix this issue.

I am a bit out of ideas to try. Anything else I can do to get access back to these websites?

Thanks

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

After an update of ubuntu 22 on my computer, Firefox does not render properly (see the screenshot of my desktop). I have tried to reinstall it but it continues to happen. All the other programs works fine, it is only firefox.

My system is: Ubuntu 22.04.2 LTS Processor: AMD Rysen 5 3600 6 core procesor x 12 Graphics: AMD Radeon rx 5500 tx

Thanks.

I've started getting this error message on certain websites (always the same ones):

The page isn’t redirecting properly

An error occurred during a connection to www.manek.org.uk.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

The same websites still work fine on Firefox mobile, so it's nothing inherent in the sites themselves.

I have only noticed this in the last few days. I had just updated Firefox to version 109 – but it's not specific to one version of Firefox either, as I tried on one of my Macs which hadn't updated yet and is still on version 107, and the issue was replicated exactly the same.

I have tried clearing the cache, restarting Firefox, etc.

Can anyone help me resolve this? Some of these are websites I use quite a lot for my work, and it's frustrating to have to do anything just on my phone.

I am getting repeated pop-up windows that say that Firefox has crashed, but Firefox is not running on my system. It is not in the Startups and I rarely use it.

Windows 10 Firefox v110.0

Is this malicious not related to Firefox? Does Firefox have a background task that is not visible on Task Manager? Or what?

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

My problem is simple. I'm trying to use this supermarket website (continente.pt) and the website doesn't load up the images of the products. I have to reload a bunch of times until it finally does. I switched from Google chrome but apparently it was a big mistake, never thought Firefox was so crap. BTW, It's not my adblocker, turned off Enhanced tracking protection and cleared cookies. Nothing works. (on annex I show firefox and google chrome being used on the same website)

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

Hello, I am a user on Mac! I am having an issue with moving tabs fluidly. Yes, moving tabs inside the window is easy but when I move them outside the window, it makes me a little uncomfortable. In the images and video I have sent, you can see that an unnecessary thumbnail of the tab pops up even when I move the tabs inside the window. This makes it harder to know if I am even moving the tab in the first place. Then it takes like 2-5 seconds for the new window of the individual tab I moved to appear. If whatever I said is quite confusing which I apologize for, I would very much recommend taking a look at Google Chrome, the browser I don't prefer, however, try moving the tabs around and outside one window and creating more windows with individual tabs. It feels more fluid or swift and easy to handle. Compare that to Firefox and a big difference is to be seen. I am concerned about this issue really because I am replacing my previous browsers, not only Google Chrome but browsers like Edge too which are capable of not having that issue, with Firefox instead and hopefully Firefox can have this capability. I also multitask a lot so I usually encounter this problem on Firefox. I hope this is fixed and am sure it will help a lot of users! Thank you!

The tab keeps crashing:

Tried new install, troubleshoot mode and deleting cache. Issue persists. What else can I do?

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

xdg-desktop-portal xdg-desktop-portal-gtk

Clicking on the spacebar, does not produce a space between words, when typing text. I'm using a Mac Mini M1, on macOS Monterey (V 12.4), along with a Logitech MX Keys for Mac keyboard.

This happens randomly, for instance, on this very message. I previously posted a question regarding another problem that I came across with the same hardware and Firefox.

I found the solution to that problem by disabling an Extension in Firefox, however, I can't begin to think where to look for what setting, that may be causing my current problem.

Since the OS upgrade, any portal that I open (especially the ones that I have my user id and password saved) crashes. One crash report can be found at https://crash-stats.mozilla.org/report/index/7d671357-2d98-4bbc-b177-4029e0221221

I have tried disabling add-ons/ exensions, disabling auto-fill, downgrading security, reinstalling (even the ESR edition), deleting Firefox files from the library/application_support - but it doesn't simply work. Not sure if this is an OS issue.

Any ideas would really help. Getting the below info on the about:crashes each time:

When using Google Sheets in Firefox, it's impossible to access the Sheets menu shortcuts (e.g. typing Alt+D+R+S to open the advanced sorting dialog) because Firefox captures the Alt keystroke and doesn't pass it to the web app.

Of course, Chrome passes the Alt keystroke to Sheets just fine so the keyboard shortcuts work as expected. But I don't want to use Chrome or any other Chromium browsers. Has anyone found a workaround to this issue? (Hint: don't say use chrome)

Until several weeks ago, new windows created through Javascript with window.open() worked. We could pass the new size, and other features, e.g. menubar, toolbar, etc. and they would show up. As of v.76.0 this is no longer true. The parameters are ignored. If we use no parameters, the menubar, etc. do show, but we can't control any new window features. We have not changed our programs at all, and window.open() parameters still work correctly in Chrome, Brave, Edge, etc. How do we get Firefox to recognize the window.open() parameters (again)?
