Firefox-Hilfeforum

I just formatted and installed Windows 10 (Pro N, 64-bit, 1909 update) and then installed firefox.

To my surprise, no videos can be played on any website (except youtube).

The video either doesn't load or shows the "Error loading player: No playable sources found" error.

I had no extensions installed, tried refreshing, tried disabling hardware acceleration; nothing solved it.

All content plays fine on chrome.

When I try to print from one website only (www.si.com), I get a phantom page at the top overlaying part of the web page I want to print. It is there on every printed page of that website only. It does not happen on chrome, nor on any other website with Firefox. See attached example. I am running Windows 7 64 bit professional and FIrefox 84.0.2

Hello As others have said recently, Firefox has become unusually greedy in RAM!

I love Firefox and it's been my favorite browser for years and years. But there it became unmanageable for me!

I'm absolutely not going to spend money to add more RAM to my PC tower, which is only three years old, and otherwise performs perfectly well for my use with all my other apps. There is 8 GB of RAM in my PC, a fast model of RAM, very fast, and expensive. You have to stop, guys, and face the truth! There is a real problem and there is no point in denying it, and saying that it takes more than 8 GB on a PC at the end of 2020.

The CONCRETE result is that we are all going to change the browser we use, it's super sad, and it is happening NOW. I don't want to change, but I have no choice. It's kind of heartbreaking for me, believe me.

Hi, I have a weird issue if I scroll with my mouse down a webpage I'll get these jagged horizontal lines in the middle of the screen but go away when I stop. Also, when I watch a video where a lot of moving is happening like if it's a hockey game the middle of the screen just that jagged line across in just the middle. What causes this and how do I get rid of it I don't notice on Internet Explorer browser and I've tried disabling hardware and stuff but doesn't work.

On screen keyboard not working when using Firefox. It will work with MS Edge, but not Firefox. It flashes then disappears quickly when in Firefox. It worked previously, but a few months ago it quit working.

Hello! On a certain adult website, all the videos play verrrry slooooly. YouTube videos play fine. And this certain site works fine when I try it with Chrome. I recently added a bunch of adblockers like Ghostery and Adblocker plus and Badger and Decentraleyes and HTPPS Everywhere. Is the problem with one of these? What can I do to get the videos to play at full speed?

Thanks in advance!

I tried downloading wondershare dvd maker and avg popped up saying it wasnt trusted. I tried leaving the alert but it wouldnt let me so i tried pressing alt f4. Alt f4 didnt work, so i chose deletion option. But it deleted my firefox browser. Naturally i had no idea what was happening when i tried clicking the firefox shortcut and it said the file didnt exist or had been moved or deleted. I checked my uninstall option on my computer and firefox wasnt even listed. I downloaded imyfoneanyrecover app after a quick google search but for some reason when i opened the app it couldnt go in window mode and half the page is off the screen and i dont know how to switch the app to window mode. I even tried downloading firefox again and it wouldnt install. I am really confused right now and i am afraid all my history, bookmarks, etc. Are gone forever. Is it avg or was the wondershare dvd maker a malware that did this? Please someone help me!

After installing the DRM content through the browser I still cannot play any videos on Netflix or Udemy.

I have run this website (https://www.jeffersonscher.com/sumo/html5-video.html) from previous answers to check and the results are attached to the question.

I have also checked media.eme.enabled and it is set to true.

I am very much puzzled by this.

I have what I think is a specific video problem. Videos from the Washington Post get the message “This video is currently not available”. Other videos, e.g. from the New York Times do work. Washington Post videos work with Chrome and Opera.

The problem is on a new Dell Inspiron 5502 running Windows 10 and Ubuntu with dual boot. The problem only occurs under Ubuntu 20.04.1 LTS. It does not occur under Windows Firefox.

The current Firefox is 84.0.2. The problem did occur under 84.0 but I didn’t have time to pursue it.

The add-ons manager under extensions has no entries. Under plugins there is only “OpenH264 Video Codec provided by Cisco Systems”.

Under preferences, performance, hardware acceleration is not selected and the content process limit is left at 8.

Running in safe mode does not help.

I had a different video problem on a pair of the hardware visible at https://support.mozilla.org/questions/1320396?utm_campaign=questions-reply&utm_source=notification&utm_medium=email#answer-1381141 This is a different machine and a different problem.

Ever since i re-installed my windows, Firefox just won't play live streams. Neither Youtube or Twitch works. I have tried everything i have seen on internet, nothing works. I do get to see them on Chrome or Brave, but i don't like those browsers, i wan't my firefox back!!!!

I can sign into medicare.uhc.com/aarp but once I am in the site anything I try to do I am signed out. I don't have this issue with Microsoft Edge so the problem seems to be Firefox. I have tried to change privacy settings but nothing seems to work

Hello, I have problem with YouTube. When I am clicking "Share" button I got screen with infinite loading. The same issue happens when I want to open menu by clicking on my avatar. On dev console I am getting a POST error: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401

I tried to: - clean Google/youtube cookies and stored cache; - clean then all cookies; - relaunch Firefox with all addons disabled; - enter via private mode with/without addons; - flush dns on dev console; - disable completely antivirus; - change DNS.

What is interesting, that problem happens only when I am logged in to my Google (YouTube) account and only on Firefox. Even on private mode it works until I do not log in to my account.

I would be very grateful for help.

Hello, its nice to have possibility to ask this questions.

I very hope that just crash and not any hackers... And here is some pity because many of logins and passwords i mere don't remember.. What can i do in this case? Will be grateful for any help.

Hello,

I've got a laptop Dell XPS 9380 that comes with an Intel UHD Graphics 620 as Video Chipset. I run in under Fedora 33 with the distro provided package (as of now version 84). The playback on some videos is choppy, I have one picture on 10 I'd say.

How can I fix that, can you point me some solution ?

thanks

I was advised to refresh Firefox as it's slow to start, but I'm concerned that all my downloads will be deleted. Is this true, as many of my downloads are very important to me.

When attempting to access https://signup.gmx.com I get the following error;

The requested URL was rejected. Please consult with your administrator. Your support ID is: < 3522328377538005653>

I contacted GMX and they have been unable to tell me why I can't access their signup page. I had my brother do a test from his home. He's on a different ISP. He is using a VPN, but this worked off VPN too. He is using the same ESR version of Firefox that I am, and he's on the same Windows 10 version I am. Also, he's using the same router I am with the same firmware. He can access the page without issue.

What I've tried;

• ipconfig /flishdns
• Checked my IP address is not blacklisted.
• reboot router
• power cycle NTD
• Run Firefox in safe mode
• Clear all cookies and cache data
• Create a new Firefox profile
• Disable Windows private and public firewall
• Rename hosts file
• Disable all firewalls in the router
• Tried different DNS Servers
• Tried different NICs (My PC has 3)
• Rebooted switches
• Checked PC for viruses/malware
• Tried different PCs in the same household
• Tried a different ISP
• Followed suggestion on https://appuals.com/how-to-fix-the-requested-url-was-rejected-please-consult-with-your-administrator-error-on-windows/ with the exception of "Add to trusted sites" I don't run any Microsoft browsers
• Read through this: https://support.mozilla.org/en-US/questions/1197304

I do not get this error for any other site. I've been trying to access this page on and off for about 6 months. It doesn't appear to be a temporary error.

Any ideas what might be causing this? thanks

just like the title says. Fedora 33, kernel 5.9.16-200.fc33.x86_64, firefox 84.0.2 (just updated today). crash report is bp-7e418e46-b201-45c7-a7c9-313840210111

doesn't matter what tab i've got open, what tabs are loaded, or even if i'm using the browser, if it's running, it'll crash around every half hour or so
