When I open Firefox I get a message telling me "Failed to read configuration file. Please contact system administrator". When I click OK Firefox opens normally and seems to be fine. Not sure what is going on here. Any ideas why this is happening and how to get rid of it?

Windows 10 64-bit Firefox 115.3.1 64-bit

Any assistance will be greatly appreciated. Thanks

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

Hello, After the last update (September 2023), I've been having issues with in-game ads being blocked, even with exceptions added and Advanced Tracking options turned off.

I got them to work for a couple of days, but now they're being blocked again. I've cleared cache & cookies, restarted Firefox, reset permissions, all have not helped.

Please advise!

I'm using Windows 10 on an HP PC screenshot of website permissions included

If I have a firefox window open (one or more), exit it, and start again, I can restore the previous session. However, if in between I open private browsing, it for some reason overwrides the session restore history with nothing. Can I somehow a) restore the session afterwards? b) prevent this from happening in the future?

i do not want the new update of firefox, and theres no way to shut off the updates. i can only switch to ask me when to install and manually install, not that i do NOT want to EVER install the latest firefox, because it truly SUCKS. it screwed up all the fonts everywhere on the web, somethings are huge and others are too small to read. i woke up a couple of days ago to an unreadable internet. i had to reinstall the last update before this one, start from scratch with all my passwords and a lot of hours of messing with my computer just to have it bearable and able to read my emails. now it keeps prompting me to install the latest. like every few hours i get an annoying pop up to install the latest. then to get it to go away i had to click on something, that downloaded it even though i dont want it. i seriously may have to switch browsers and abanadon you all completely because thats how bad your latest update is, and thats how much it sucks to not be able to stop it form harassing me every few hours to instal it....with no way to turn it off completely that i do not ever want the latest crap update.

On my work laptop, I disabled "Recommended by Pocket" to avoid distractions.

On my personal laptop, that setting is already enabled. But I never see any stories recommended by pocket when I open a new tab. What can I do about this?

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

translate beta: Please help to deinstall this annoying feature. Setting <browser.translations.automaticallyPopup = false.> doesnt do anything. uninstall mozilla and re- install again? thanks'

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

Hello,

On my firefox browser the Duo Security website keeps looping and not letting me login. I have tried private window and also have tried to install firefox again. The Duo security website is able to load on other browsers like Chrome and Edge without any issues. I also deleted the appdata and app profile and it is still not functioning. Any other recommendations that I can try?

Website is: https://api-263d2dfd.duosecurity.com/frame/frameless/v3/auth?sid=frameless-0e4e2d68-a138-4a07-8ad9-d7aae0f9fe5d&tx=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJkdW9fdW5hbWUiOiJzcGlrZXAiLCJzY29wZSI6Im9wZW5pZCIsInJlc3BvbnNlX3R5cGUiOiJjb2RlIiwicmVkaXJlY3RfdXJpIjoiaHR0cHM6XC9cL3NoaWJib2xldGguYXJpem9uYS5lZHVcL2lkcFwvcHJvZmlsZVwvQXV0aG5cL0R1b1wvMkZBXC9kdW8tY2FsbGJhY2siLCJzdGF0ZSI6IjVlMDNmOGM5OTcxM2MxZDdhYzRkNjlkMzZlYTAxYTU4LjY1MzM3MzMyIiwiZXhwIjoxNjk1OTU5NzU0LCJjbGllbnRfaWQiOiJESURLMkhSNEdGMTVJWUhMNEQ3VCJ9.wnLBrsdlaHjvudLT9w6rcD43QyQurgYR0UGIHYg2BXqP8TqNiFP5PN1C3l8jtYgA37LHrGbP6YvOYlY1MMOpYw

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

I do not have this problem with any other browswer, am using Win 11. have tried run troubleshooting and have reinstalled firefox. am about to give up on firefox after many years as there appears to be no help for this problem

So on certain websites when I zoom in these weird white lines and boxes appear on the screen. they only appear when zoomed in and when I put my cursor in certain places. Usually when I move my cursor they disappear but I was able to catch these. Im on firefoxes most recent update on a lenovo laptop with windows 11. As far as I know this only happens in firefox, another thing is I recently updated my drivers due to screen flicker.

All that was required was synced from my old laptop to my new laptop. But I just cannot find an option to sync my Notes from my old Laptop. I have looked through the Help section but could not find any help. Also can Notes be synced to my Firefox browser on my Apple/Android phone. Thanks in anticipation
