منتدى دعم ”Firefox“

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

I get so choppy scrolling that my eyes hurt after few minutes. Doesn't happen on Chrome or Edge. It is most noticable on YouTube. It feels like it's running at 15fps

I've been lead to believe in previous editions of firefox you could turn off the redirect message and instead just allow firefox to redirect.

However now (as of 112.0.1) i can't find any way to do this. I repeatedly get redirect message and i would prefer the browser just do the redirect instead of having my click a link. I know exactly where the redirect is coming from and i have no problem with it and i don't need it to have a warning.

I have a new installation of Ubuntu 22.04 on my 2015 Lenovo IdeaPad 300. I have a new SSD HD 1 TB in size and it should work, however, Firefox keeps crashing. Other apps are crashing too.

For the past 8-10 days, every time I try to log-on to: https://selfservice.telkom.co.za/rococo/public/content/interstitial I click "Login" under the Mobile & Home heading and I receive the following message returned.

Bad Request The request could not be understood by server due to malformed syntax.

I have used MS EDGE browser and do not get the same problem, it log's-on OK.

As such it seems that it is a Firefox problem.

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 browser displays many websites, emails, etc. using a strange garbled font (see attached image for reference).

I already checked the preference setting for allowing websites to select their own fonts. The issue also persists in Troubleshooting mode. I have also used the "Inspect element" tool when this has occurred, also to no avail. I imagine at this point the only real solution is to delete and reinstall Firefox, but I'd love to hear if someone has another solution! Thanks!

Note that text in bold / italics often shows up just fine. I can also copy-paste any of this text and it displays correctly.

I have been having issues with the checkout page of my website. My problem was most likely coming from our payment provider causing issues with updates. I switched payment plugins until it gets fixed. (In case you would like to know the extent of my troubleshooting. I ended up installing a brand new wordpress install on a subdomain and the error still occurred.)

This is most likely not related to my initial payment provider issue. When I view issues in the console I keep getting error messages. These issues affect my ability to use the checkout page on my Firefox. We are currently processing payments successfully. These errors do not show up on Chrome.

This is the website page I need help with. https://heartlandforest.org/checkout/

I can't tell if this is happening to everyone or just me. I don't know which resources were blocked or where to fix this. My website and my server do not have a CSP. I have been looking for an answer for over a week before attempting to try asking here. Every issue I have noticed in the past week on my site has been one big red herring after another.

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?

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?

When I browse carsales.com.au and redbook.com.au I get the error message:

We want to make sure it is actually you we are dealing with and not a robot.

Please click below to access the site.

Why is this verification required? Something about your browser’s behavior has caught our attention.

There are various possible explanations for this:

   You are browsing and clicking at a speed much faster than expected of a human being.
   Something is preventing JavaScript from working on your computer.
   There is a robot on the same network (IP 180.150.36.41) as you.

Having problems accessing the site? Contact support.

I have accessed these websites many times previously without problem. Other websites appear ok.

I'm on Windows 10 pc.

Many 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?

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

Firefox bowser stopped working suddenly. Tried uninstall and install multiple times with multiple options.

Still not working even after cleaned all Firefox related files using uninstall tools and installed again.

Why does the Mozilla Firefox snap for Ubuntu keep changing the value of browser.opaqueResponseBlocking away from the default and selected FALSE setting to TRUE? This makes Firefox nearly unusable since the streaming video keeps being cut off when Mozilla Firefox snap for Ubuntu keeps changing the value of browser.opaqueResponseBlocking randomly during use. Specifically this is the 116.0.2 (64-bit) Mozilla Firefox snap for Ubuntu canonical-002 - 1.0 that is installed with Ubuntu 23.04. Please advise.

How do I remove the scam pop-up that won't let me access firefox on my iphone? The pop-up says "your apple iphone is severely damaged." I can't open a new tab or delete the current tab.
