Firefox Support Forum

Hi All,

Deploying few  features for a system using firefox browser. 

In once scenario, on a user action , showing an alert box and redirecting page to new URL. On this , new page is loaded and after loading the page, the alert box disappeared This is working in my last system configuration, which is MozillaFirefox-78.9.0-112.54.1.x86_64

I am upgrading the system now I am using MozillaFirefox-115.3.1-150200.152.111.1.x86_64 In this configuration, the previous alert box is not removed when page is reloaded Any configuration/setting has to be done in firebox browser to automatically close the alert box?

Every day. Videos won't play. sometimes one restart of firefox will fix it. sometimes multiple restarts are required before it'll work. The loading bar at the bottom of the video (on the seek bar) indicates the video is loading but it won't play. There have been times where I have disabled every single add-on and it would not work. Add-ons do not seem to be the cause. I have tried it in a private browser window with no joy. I have refreshed firefox, I have uninstalled and reinstalled it. I have tried disabling my antivirus. I have tested videos on websites in other browsers with no issue. The issue seems to be with the video player itself. overlays seem unaffected, I can use the seek bar and it shows the captions. I have tested different websites including Youtube, Vimeo and Steam. I tried many tens of times to get it working today to no avail. finally when I closed nearly all my tabs, the video worked (but I had also opened TOR and run avideo in that), I am not sure if this is the cause. If the cause is having multiple tabs open, this is an issue for me. I have a learning disability and likely ADHD and I have a set of tabs as my homepages so I don't forget things. If It's not the mutliple tabs, then what else can I do?

Windows, Ver. 120.0.1, 64-bit. Hardware acceleration enabled.

Many tasks on all websites result in GPU usage spikes. Very basic functions such as page scrolling or entering text often take a half second to register, making the browser feel unresponsive. I do not have a bunch of tabs open either and am not using any other applications that would be power-intensive.

Using an RTX 3050 Ti Mobile. Newest NVIDIA drivers, 546.29.

GPU usage spikes to over 10% when just scrolling the screen. Help!

"I've been experiencing an issue with Mozilla Firefox where it doesn't display the Silver Taxi Sydney Silver Taxi Sydney website correctly. Other websites seem to load fine, so I'm wondering if anyone else in the community has encountered similar problems with specific websites on Firefox. Are there any known compatibility issues or common solutions that could help resolve this problem? Your insights would be greatly appreciated!"

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

Hello, i switched from chrome and loving the firefox and have plan for sticking to it, its great but, There is a issue iam facing which is slow video loading example in Youtube, in firefox the video have to download certain amount so that it can show the video,which causes stutter and slow loading, in chrome its instantly loads we who using with limited internet speed facing this issue, hope you will fix this, thanks in advance You guys are great, sending love

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

Our IT specialist at UW-Madison is stumped and suggested I reach out to Firefox. He was helping me troubleshoot why Firefox keeps saying it's sending a code to verify my account, but I never receive the code. He has added the "accounts" email to my contacts and I don't know what else to do or try. Any ideas from the community? I need my bookmarks after upgrading to Windows 11 and can't imagine trying to recreate them all.

Firefox V102.0.1 up to date. Right click to open link in new tab - new tab is displayed, link is shown in new address bar, nothing is displayed in the window. Thoughts?

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Firefox 120.0 on openSUSE Tumbleweed.

Google Maps (https://www.google.com/maps) results in CPU being pegged at 100%. No other tabs open. All I have to do is load the URL and do nothing else. This behavior is repeatable. CPU stays at 100% until tab is closed or browser is shut down. Sometimes the browser will hang and its PID has to be killed.

Offending process:

The problem comes up for two days after Windows crashes with a blue screen. After POR Windows recovers itself and now works, but FireFox and Thunderbird chrashes immediately after start. Do you have an idea, what can I do? FireFox crash ID: bp-c4fe47cd-45dc-4024-8cc1-4a2220231204

Thx, Flo

Dear firefox team, recently I use firefox on my windows 10 pro and when I use to open YouTube. Com it opens but when I play a video it starts buffing after one time of refreshing it plays and it is same at all time so please fix it

I remember having: Panaroma, 2 tab organization and several YouTube addons to enhance my experience like Adblock, unhook, dislike return. And with several tabs as checkpoints for my search but I couldn't separate them and also it lagged a lot when having unloaded tabs. LibreWolf provides a better service maybe you could understand the frustration that Firefox had on me. There's no section for videos.

Downloading each page of a subscribed newspaper takes about 30 seconds. How do I eliminate the slow response? By the way, I deleted Firefox and reinstalled it. That fixed the problem only temporarily.

Thank you, Mike

Within the last week or so, a certain website (libsyn.com) that serves Podcast audio has been doing something strange to their content that causes Firefox difficulty when playing back in-browser. If I try to jog/skip through the audio, certain portions will cause the time to continue advancing, but Firefox will not play any audio back. Here's a sample. Note that if you allow the full URL to be loaded, then load the stream into VLC, VLC is able to play the audio just fine without any issues.

Hello,

I've read and tried the fixes to open the newly updated (deleted and installed 3 times) Mozilla Firefox and nothing is working. I've pressed down alt to open in safe mode and I am unable to get it to open. I've looked for the Facebook plugin to disable it (saw a comment on that) and the plugin folder is empty. Is there a help desk with an actual person that can figure this out?? It is quite alarming to see so many other people with this problem and no real help from Mozilla employees themselves. HELP!!

This problem just started recently, where I can't unmount an external USB drive without getting this error message:

The disk "Projects" couldn't be ejected because "Firefox" is using it.

I hate to keep quitting FF just to unmount a USB drive - that means logging in again to various web accounts.

My only extensions running right now are Enhancer for YouTube, Grammarly, and Facebook Container.

What's preventing me from unmounting a USB drive?

Thanks!

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

I installed Firefox on a new laptop and synced it. The bookmarks all were transfered. But when I log into some websites they do not recognize the password, even when the passwords are correct and still work on my previous computer/Firefox brow’ for ‘Firefox.
