Firefox Support Forum

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

Hello,

I'm seeking help because sound is not working on Firefox. All other software are able to produce sound on every speaker and headphones I have. The speaker logo does not appear in tabs were videos or music is playing and firefox doesn't show up in EarTrumpet. It does show in the volume mixer but no bar appears to show it is displaying sound while media is playing.

I'm running : Firefox version 119.0 64 bits Windows 10 64 bits version 22h2, OS build 19045.3570

I've tried :

1. Restarting Firefox
2. Muting/Unmuting Firefox in the volume mixer, in firefox tabs too
3. Downgrading to version 118.02 32 bits
4. Uninstalling all my audio drivers followed by a restart (they got re installed but no change for Firefox)
5. Restarting Firefox with all addons disabled

I'm running out of solutions.

Kind regards

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?

Hi,

I experienced at least two times recently that the browser on windows 10 looses all the opened tabs and pinned tabs too. Last time it did also that when I closed the program and it opened itself again immediately without tabs and closed itself down again. Next time I opened the program there was no opened tabs at all again. I have the latest version for windows 10.

What do you suggest me to do?

Thanks for help! Br, Balint

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.

I'm having an issue with Fidelity Investments website logging me off after 5-10 minutes of inactivity. Before Fidelity's website redesign, I could go at least 30 minutes or more without having to login again. It seems now I have to login constantly.

I have contacted Fidelity, but the said it was a Firefox issue, however, I cannot find any information about this issue (or I don't know where to look).

How do I extend the time before needing to login again? Thoughts on if is this even a Firefox issue or is it Fidelity's website?

Thank you!

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

Dear Sir/Madam,

I need help with Mozilla Firefox 119.0.1 (64-bit) version which is almost not working internally without Internet link. When I try to open local internal site Mozilla Firefox waits to open https://www.bootstrapcdn.com/ Internet location which is unavailable because we are using the browser in isolated network and it is waiting for this site for more than 15 minutes before it opens the local site.

This is not the way we are expecting the browser to work so the question is can we disable this requests in Mozilla Firefox that we were not aware of and that are not asked from out side?

Thank you!

Why is this so difficult? I keep getting the attachment. How do I stop it? I NEVER WANT FIREFOX TO TELL ME THERE IS AN UPDATE. I will check and update when I'm ready. How do I stop this?

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'm watching a YouTube video and taking notes simultaneously. It used to work fine, but today, possibly after update 119.0(64-bit), it's not functioning properly. I couldn't resume my video with <space> after switching back from my note using <ALT>+<TAB>.

Any solution for this? Or should I consider downgrading my FF?

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.

I moved to Firefox because I have autism and someone told me it would help block the popups and moving content that makes using the web exhausting and difficult. And it does!

The trouble is, it replaces them with something worse – a grey screen that rolls continuously from left to right. It's impossible to focus on text with such intrusive visual distraction, so I have to shut the page down. It seems to occur on so many websites that at the moment it's not worth trying to use the browser.

Half the problem is that I don't know the right term to describe it, which makes troubleshooting a bit complicated. Hopefully someone will recognise it from the description, though – if so, is there any way of stop it moving, please?

Thank you!

Hi Guys,

I use Firefox personally and for business. I use a lot of very useful extensions and like many users I customize my experience. I have found that the number of extensions I use every day is larger then can be shown on the extension toolbar. I am aware that clicking on the "jigsaw" icon will open up all the extensions, however this is not practical and wastes a lot of time. I would like to substantially reduce the size of the search box and increase the available size for my extensions to be in one click territory on the toolbar, how do I best achieve that please?

Cheers

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!

Hello! Since updating to the last version (119.0.1), Firefox started keeping my open tabs between sessions. This is a behavior I don't want, and the only solution that I found told me to enable "clear history on close", however that is also not ideal, because I don't want to clear my history. The "Open previous windows and tabs" setting is off and my homepage is set to Firefox Default. I don't know where else to look for such a setting, except in the about:config, but even there I'm not sure which one is causing the issue. Any assistance would be appreciated.
