Firefox Support Forum

I was using my computer and Firefox all day to watch videos, browse twitter and Tumblr and whatnot until around 15:30 my time, when suddenly Twitter stopped loading my timeline. I thought it was an issue with Twitter or my computer. I restarted my PC twice so far and rebooted my modem (completely unplugged, left it alone for a min and plugged it in again).

I still cant load my twitter timeline, not even in private with all extensions turned off. It does load Tumblr, but like 80% of the pictures/gifs, even profile pictures do not load. When I search for something on Duck Duck Go it sometimes works but most times it just stays blank. Youtube videos either do not load at all, or stop loading/load endlessly at some point. I am still able to navigate the Youtube website tho.

I really do not want to use Chrome, but the latest update is just unusable. Am I the only one?

(I forgot the word for modem, dont judge me.)

After the newest update Firefox fails to upload some pages. I reset the internet and wifi but that didn't fix the problem so I try Edge and it worked fine....

For example Facebook load fine but if I try changing the cover photo the menus (pull down panel) never appears. Earthlink home page never uploads. etc.

While I switched to MS Edge all the pages mentioned above worked fine.... so it is not the Wifi or the internet connection

I've opened a video in Full-Screen on my 2nd Display. I know it's in Full-Screen. I am watching this in Full-Screen on my 2nd Display. I do stuff on my 1st Display and i am watching a video on my 2nd Display in Full-Screen at the same time. When i switch back to 2nd Display (click with my mouse on the video which is running in Full Screen), a warning message will pop up that i am watching a video in Full-Screen. YOU DON'T SAY!

I made changes in my config full-screen-api.warning.timeout = 0 full-screen-api.warning.delay = 0 full-screen-api.transition.timeout = 0 full-screen-api.transition-duration.leave = 0 full-screen-api.transition-duration.enter = 0

It's working until i leave my mouse pointer on my 1st display and click on the Full-Screen video on my 2nd display with the Full-Screen video which is running in Full-Screen on my 2nd display in Full-Screen because wanted in Full-Screen on my 2nd display.

If you answer is cause of security reasons, i saw this JOKE Phishing attack example on https://feross.org/html5-fullscreen-api-attack/ So explain me why "full-screen-api.mouse-event-allow-left-button-only" is set to True?

I know many People are mentally challenged but do not punish us. So tell me how can i remove this Full screen Message warning entirely.

Thank you.

Having a problem with an mp3 content on all sites. In console I can see error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: Error no decoder found for audio/mpeg

The same error shows when starting firefox from terminal: [Child 1234, MediaDecoderStateMachine #1] WARNING: Decoder=11dddc400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error no decoder found for audio/mpeg: file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166

It seems like not a system problem, because I can open and listen an mp3 files in quicktime. And chrome browser also not having any problems playing an mp3 content.

Firefox installed with dmg downloaded from site, but also tried install with brew - same result. The problem occurs in incognito mode too.

Hello I think I found a bug in firefox settings. Recently I upgraded my antivirus to bitdefender total security with firewall module. I set it to ask me about permission to connect with internet for every process on windows. I was very surprised to see that default-browser-agent.exe tried to connect to internet. I checked my privacy and telemetry settings again, but they are all disabled. I checked internet and found this mozilla article: https://firefox-source-docs.mozilla.org/toolkit/components/telemetry/data/default-browser-ping.html You can read there that "opting out of telemetry does disable it; the pref value is copied to the registry so that the default browser agent can read it without needing to work with profiles". I opted out from all possible telemetry, both visible in settings and hidden in about:config(based on lists of telemtry-related options from web).

Is there any way to actually disable this ping? It tries to connect with internet every 24h. I guess I can simply remove it from windows task scheduler but I want mozilla to respect my privacy settings and disable it solely using browser built-in settings!

Old article on web stated that this can be easily disabled by disabling setting responsible for sending technical data ( https://www.bleepingcomputer.com/news/software/firefox-now-tells-mozilla-what-your-default-browser-is-every-day/ ) but I have it disabled and it is clearly ignored!!!

P.S. Sorry for screenshots in Polish but I guess you can understand them even without language context.

I've been having issues with Firefox since the latest update. Currently using Windows 11 on Lenovo compact PC.

I cannot load any Google related website and some other specific websites, including Instagram, Airtasker and Youtube. All documents on Google drive are inaccessible, Gmail cannot be opened and Instagram is only showing feed from yesterday. Google Maps appears to be working fine but I'm not sure if this is just luck. It seems all saved content (via cookies?) are normal, but I cannot get any real time update.

I've tried removing cookies for Google related website but it does not work. Have also reboot and restarted several times. I would want to avoid reinstalling Firefox as it's time consuming and I might lost all my saved logins.

I can no longer 'Select all' of a simple html table displayed in the browser. The header lines won't select no matter what I try. The browser only allows the body lines to be selected, and subsequently copyied.

On Thursday the pages I have used every day for years worked fine. Today pages like Ancestry.com, familysearch.org, facebook, twitter. None are loading. Was there an update that happened since Thursday? How can I go back to the previous version that worked perfectly? I did check and my system says I'm using the most current version Win10 computer (2 years old if it matters).

So, today i installed the latest update to firefox (at least that's when i was notified). I installed it. Then for some reason i got notified it's not the latest version and installed another through about -> help. I usually keep it up to date so not sure why 2 installs in same day. In any case, i am now on 116.0.1 64 bit. And that completely broke my browsing and firefox.

Some of the issues im experiencing. 1. Google search is not "working". I type something into the search bar, and when i press "enter" on the keyboard, it just moves to next line and i can type again. This however was not happening before. It works normally on chrome/edge and only started happening on this release. 2. Almost anything "interactive" is broken, or not functioning. For example, my chess.com settings cant be loaded no more. Loads it fine in other browsers. 3. Youtube is not functioning properly. Sometimes it loads, sometime it doesn't 4. Some pages aren't rendering properly.

It's as if javascript or some other thing is not loading anymore. I tried moving back to older versions, however, that did not fix anything. Everything was fine untill i upgraded today.

Audio on my PC works except on the firefox browser. The browser is not muted, I've checked the volume mixer, i've reinstalled firefox, but nothing seems to work. This just started occurring a couple days ago. When I restart the pc, i will get audio from firefox for a couple seconds then audio stops.

I downloaded a app on my Macos Big Sur workstation (https://kevin-de-koninck.github.io/Clean-Me/) and I ran it (I did not have the option "User Preferences" Selected) Somehow, after rebooting my computer shortly after, it had logged me out of my Firefox account. That shouldn't be a big deal right? Somehow at the same time my Lastpass password program does not have that account saved in it. It has a secondary account ( that used to be the primary, but I guess I switched it at some point) that I can login to, however whenever I login to it, it says

I woke up this morning and realized my youtube wasn't working right. It was loading endlessly and wouldn't play right away when I clicked a video. I thought at first it was a computer issue so I restarted it; but that didn't change anything. Then I thought it was an internet thing, so I switched to my mobile hotspot; but still nothing changed.

I've restarted my computer 3 times, restarted firefox 9 times and done just about everything I could find online. I turned off the recommended hardware settings, went into troubleshoot mode (although I'm not tech savvy so I didn't really understand what to look for), made sure firefox was up to date, cleared my cache and cookies, made sure all my add-ons were up to date; and still nothing.

And it's the same for Twitch. It just loads endlessly and doesn't play anything. It doesn't give me an error or a bug notification; just shows the gracy spinning circle and nothing else.

The only way anything loads is if I turn the quality down to the lowest one possible and have it paused for a minute to let it load on its own.

It works fine in Microsoft Edge; but just not in firefox.

I've notice since last night that in certain instances left clicking on something results in no response. There are a couple of cases where this is happening. In Google image results if I click on an image, that image should open up in a popup in the upper right corner. However, now when I click on the image, nothing happens. The other instance is when I do a Google search on a certain subject, at the top of the results is "people also ask." Next to the results in a drop down arrow to expand the results. However, clicking on the arrow also results in no response. I am having no problems at all using Microsoft Edge. I did restart FF in troubleshoot mode and the issues went away. So, apparently there is something wrong with FF in normal mode. Using FF version 11.6.01 64-bit with Window 10. Also, I have not installed any add-ons in a long time. On other thing. It seems some pages are not rendering properly. For example I tried using DuckDuckgo to see if the above problem was specific to Google search. However, when I typed the DDG address into the address bar, the page comes up blank. Thanks in advance for any help.

Hello everyone. The calendar add on at the side of my Gmail account does not open after the latest Firefox update (116.0.1), but it does work in troubleshoot mode. Could you please advise? Thank you.

Just FYI, these two add-ons now cause problems when loading some web pages. Just started this AM (8/5/2023):

Thanks, KW

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

not talking about settings smooth scroll. I have it disabled. but with the new update when clicking in the scrollbar, it has smooth animation and scrolls 10 times slower. fix it.

I am frequently needing to clear the Cached web content, when doing development work on a website. I always need to remember to remove the check mark from the Cookies box. However, I sometimes forget and loose dozens of log-in cookies and need to reset them, which is a big pain.

I was unable to find anything in the Firefox Advance Configuration settings. In Chromium and Chrome browsers, only the Cached images and files box is set with a check mark. If I cannot change the default for Cookies, this is reason enough for me to switch browsers, despite using Firefox for many years.
