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 there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

Best regards, Walter

Hello - I keep searching for various fixes to this, but nothing seems to work. I have the latest version of firefox. Macbook user. Catalina 10.15 I find that with almost any website that I'm trying to log into, or enter a credit card and other information, the browser does not show these items, pull downs, forms to fill in etc. I'll go thru a whole process of something, and will be directed to click a box or some such that just isnt there. So I move over to Safari, and the entire page loads. I've adjusted the privacy, cleared cache etc. It's like I'm on an ancient browser.

Any help welcome.

Prior to a few days ago I could type "Ama" into the address bar and then press Tab to start search Amazon. However, it now goes to a recent history item instead (see image). How do I fix this?

Ark extracted Version 119 files into /home/Downloads/Firefox/Firefox. I tried ./update from the BASH command line, but didn't know which argument(s) to add to that command. I'm hoping to update Firefox 78.14 ESR to a recent version, whether ESR or not. Thanks for your help.

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

Hi, some years ago sending tabs to a device worked fine, but for some time now it stopped working. Is it just me or is it a general bug? All my devices are listed in my account. It also shows that they are updated frequently. I tried sending from Windows-Firefox to Android-Firefox and back. Nothing worked. What can I do? Best regards, Eric

I recently upgraded from Window 7 to windows 10. Ever since, the spacing between the bookmarks has significantly increased. I read several post about this and they all seem to be looking for something in Firefox. I think it has to do with something in windows 10, not Firefox. Any ideas? I've already done the Density/Compact thing. Slight improvement, but not anything like it was under Window 7.

pdf files fail to download in Firefox, but not other browsers. In particular these sites:

https://heinonline-org.ezproxy.socialaw.com/ https://1.next.westlaw.com/ https://www.medicare.gov/my/eMSN https://fc7.fastcase.com https://www.mlb.com/

However, I can download from non-password protected sites like:

https://www.irs.gov/ https://www.ssa.gov/ https://www.sec.state.ma.us/

Downloads work in other browsers. I've checked various items in the settings and none of them help.

I like Firefox, but if it won't, I will go elsewhere.

Firefox has been crashing constantly for a few days now. Every time I start the program, it starts using more and more GB of RAM until it crashes at over 100 GB. I have already deleted and reinstalled the program and cannot explain why it is using so much memory. Can anyone help me?

Yesterday I was playing videos on rumble fine. Sat my laptop down, picked it back up after waking up and suddenly no sound on any rumble.com video. Youtube plays video and audio fine. So does X and truth social. In fact, any website plays audio EXCEPT rumble.com. Its not Windows related. Its firefox related. I installed Chrome and rumble.com plays with sound fine. I uninstalled firefox and reinstalled and that didnt fix it. I have rumble installed via WebCatalog an it plays videos and audio fine. I then installed Firefox nightly and never signed in or anything and still rumble isnt playing sound. Its rumble+firefox=no sound. And it appears to be happening to others too on other help forums. DOES ANYONE KNOW HOW TO FIX THIS?

Whenever I go to a Google page (tested on Google.com Docs, Sheets, Forms) the page crashes. The issue started sometime around this afternoon.

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

Whenever firefox has multiple tabs open and on any single tab youtube is running i find youtube to crash lag and even crack itself by audio playing with struck video. FYI the same issue is not experienced in other browsers like brave for instance . I hope you provide attention to this problem and solve this issue as soon as possible and as I mostly use firefox to browse and use its dev tools.

Hello

Just to report Firefox 121.0.1 (64-bit) unable to upload any video formats on youtube and always having invalid video format error. I'm unable to upload even that videos what was already successfully uploaded some times ago. I using Microsoft Edge now to upload on youtube and it is fine with all my videos. Hope you can fix soon.

I can't get Amazon back as a search option Bing is one of the search options selected in search settings, doesn't appear.

If I install an older version will it be ok. Why do they keep installing new updates which cause issues with the one I am using. I installed Opera and will give it a try. Firefox keeps changing things that work.'bold text'

Firefox runs fine most of the time. If I right-click to download an image, or click a link to download a PDF or other file, or Save HTML, I see the "Save file" dialog, click Save and then Firefox freezes up for a while, maybe a minute or two. Pages won't scroll. I can't switch tabs. I can bring up a different firefox window and it redraws its contents, but I can't scroll or do anything else.

This didn't happen a month ago, then one day after a system upgrade, it happens every time. I'm using FF 123.0.1 on Arch Linux. 64GB RAM, so it's not a memory shortage. I have upgraded one or two times more since the upgrade when this appeared. Chromium is not affected, Thunderbird is fine, and all other software continues to be fine as before, including when saving files. Only FF has this problem.

What is the problem and solution? Are there ways to gather more info to diagnose the problem, if needed?

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.
