Firefox Support Forum

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

All of a sudden, i noticed a copy of 'Other Bookmarks' on my Bookmarks ToolBar.

It is an exact copy of my Other Bookmarks, located where it normally is. There is no way to delete it, not with right click or from the menu tree. i cannot drag it either. When i reset FireFox, it is gone, but then shows up unexpectedly.

When i hover over Bookmakrs Toolbar, it is not visible (all others are), and when i 'Show AllBookmarks', it is visible, but at the bottom of the list.

Any help would be appreciated.

Hello,

I'm beginner in development. Today I'm working on some CSS files.

But when I reload, the content don't load the new features. I've try to clear cache, remove stockage on the console , and also try command + f5 (on iMac).

The only one solution I've founded is to clear cache , leave firefox , shutdown computer and restart.

Very contraignant. I've test on Chrome and it work well. So I don't know what I need to do to...

I'm using MAMP to lauch app on local

Starting today, Google Calendar will not load. There is none of my data in it. I cannot navigate. This is only in Firefox. A blue color streams across the top of the screen as if it is trying to load.

It's been a while since I noticed Firefox video is laggy on every website. I thought it was about some driver problem but everything else seemed to work well. I downloaded Chrome and it didn't have any problem running any video.

I tried clearing Firefox's cache and I tried to "refresh Firefox" on about::config, but it didn't work. I don't have any missing system updates, I'm running Firefox 84.0.2-1.fc33 on Fedora Workstation 33.

I don't like using Chrome so your help will be really appreciated.

Thanks in advance!

Using live server on visual studio code (127:0:0.1:80). The minute i click it, pop up with mozilla crash report shows up. Not sure as to why it is happening. Live server settings has been done accordingly. it would be of great help if this is sorted.

Firefox slows down or even freezes for a longer time when I am typing in text in forms (like new GMAIL messages, search boxes, etc). Especially when I make mistakes and delete some.

I have Refreshed Firefox and removed the Adblocker add-on, which I thought might cause the problem, but the problem persists.

Any idea how to tackle this?

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!!!!
