Firefox-Hilfeforum

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.

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.

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?

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

After my PC rebooted, firefox will not open unless I rename the EXE to something else.

Steps already taken 1) Refresh firefox 2) reinstall firefox (including after wiping all data from PC) 3) delete parent.lock 4) check Microsoft account - I am NOT content filtering. I am the sole user in my "family" and the app lists me as the organizer. I have zero way to even set UP content filtering.

I am at my wit's end. I can't set it as a default browser because the EXE doesn't match.

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

Got a problem on two separate computers: Mozilla Crash Reporter keeps popping up when Firefox is not even running. I'm guessing that my antivirus avast is interfering with the update service. I'm I right or wrong? Otherwise, does anyone know how to interpret this? This is the report:

This report also contains technical information about the state of the application when it crashed.

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

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.

I have two monitors, and I usually keep a stream/youtube video open on the second monitor while I browse the internet/play games. I used to do this all the time in OperaGX, but I recently changed to Firefox, and I've noticed that after about 10 minutes, the video or stream stops playing, and I have to manually pause and unpause the stream to get it running again. I have checked online, and I found a fix related to the about:config setting "network.http.throttle.enable" as "false" and the "network.http.throttle.version" as "1", but my firefox already had these settings like this.

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!!

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

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!

I have recentlly built a new pc. I have updated windows, graphcs drivewrs and checked that the ram is good. I have submitedn the crash log: bp-c292b4b1-dbec-41f5-a25f-5823f0231202

I have been getting this error message for over a week now, PR_END_OF_FILE_ERROR. My internet is fine and I have restarted my computer a few time since the problem started. I have added some sites to the Exceptions list but even then they don't work properly. I have tried refreshing Firefox and changed the profile and they both didn't fix the problem. I am sadly not knowledgeable enough to make sense of the Web Developer Tools. The attached image is what my YouTube page looks like after add the site to the Exceptions list.

So to cut it short, i have an issue with not just firefox but almost all other browsers too. I have tried Firefox, Chrome, Opera and Edge. Both Firefox and Chrome will instantly close when i open them. As in, the window will open and immediately close after barely half a second. This has happened with Chrome and Firefox, yet Opera and Edge dont seem to have this issue. I am a Firefox user normally so this does make it a little annoying. Any ideas on why that is?

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?
