Firefox Support Forum

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.

Using Nord Pass extension on Mozilla fine until today, when clicking on the green icon for stored username and password, this appears - "sudden error message : can't handle ITEM/URL_SEARCH type message"

For 8 months i am still getting tab crashed messages whenever i try to pause then replay videos. I have sent crash reports and shown them on the help page and get no real answers.

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Here is screen shot:

My iMac is OSX. I use Firefox browser most of the time. I had used Safari years ago. Chrome had rarely been used. Firefox problems recently began. Please help.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Hi, My Firefox of recent is extremely slow or sometimes fails to load a page. I thought it could be some extensions I added about protection from tracking etc...I tried disabling them, but not sure if I succeeded. But the problem still isn't fixed. I don't think I will figure the issue out. Thanks

Hey!

When you're going to fix the Ctrl + C issue?!

I'm sick and tired of restarting your f*g browser each time I need to paste something in a form on a page. It's frozen each time I press Ctrl+C somewhere outside your browser and return to it. I am forced to close it and restart it! It's been a year since this bug or even more.

Thank you

As of 21/11/2023, I can no longer use several chat services that had previously worked on Firefox, for example Santander bank and EDF. Plus, the POWR widget has stopped working on one of my favourite websites.... it used to pull in the charity's Facebook content but now all I see is the text and no imagery. All of these functionalities work fine in Google Chrome and Edge so what's wrong please? Thanks in advance UF https://www.aldingbournetrust.org/make.html

When I try to login to the Tesco website I get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

But I'm still unable yo login to this site.

I have Firefox as my browser on my laptop. Today I have been getting numerous pop-up messages from McAfee (which I do not have- I use a different web defense app) saying I need to renew my subscription or virus detected. Nothing I do gets rid of these pop-ups, which keep coming back (see example below) . How can I stop this from occurring? HELP!!

Hi, for months now, Mozilla, keeps crashing, or asking me to install new updates very frequently. Today it told me I have an old version (I do not) and that I need to create a new profile. I love your privacy policy but am about to give up your product. I have an IT dep and they were not able to help either. Best of luck fixing these bugs

I've used FF for years and always had - "Open links in tabs instead of new windows" and "When you open a link, image or media in a new tab, switch to it immediately."

Until very recently this worked well.... now there are two identical tabs opening the link and the switch to immediately does not work.

Dear Firefox Community,

my ff browser won't open the following websites:

https://www.haaretz.com/ (here it says: Error 54113) and https://archive.ph/ (this won't open at all without any notification)

Could you please let me know how get them to open?

Thank you!
