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.

I have cleared History plus cookiies and site data and cached web content

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

Hello- I am having a very strange thing when using Firefox. I type and certain letters pop that I have not typed. It is different letters that are affected. it has been the E a number 2 shows instead s a m shows instead. There have been others but I did not make note, My solution is to close firefox and reopen. I have updated to newest version. Do you know why this is happening and a better solution. Also when I go to Chrome the letters do not transpose. HElp Stephana

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

I am in Europe. My Bank is in the U.S. I can no longer log on and access my account through this Mozilla Browser.

I continually receive this message:\Secure Connection Failed

"An error occurred during a connection to click-notification.capitalone.com.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

This is my ticket (116230) from my initial request.

What can I do?

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

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.

Hi Firefox Team, I am a university student, and I keep getting these messages below, especially when I am doing research for my assignments; it is painful as time is of the essence. I need your help asap. I have already cleared my cache, and cookies Thank you The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If a firewall or proxy protects your computer or network, make sure that Firefox is permitted to access the web.

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!

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.

When watching videos on YouTube or Amazon Prime, Firefox will eventually stop recognizing keyboard and mouse input in all windows and tabs. This can happen after just a few minutes of video or after hours. It affects nearly all input: typing or clicking in webpages, the toolbar, the address bar, etc., though I can click the 'x' button to close tabs. When I close the final window, a dialogue will appear stating that Firefox is non-responsive and allowing me to kill the process. This seems unusual, because the OS's system monitor indicates there is plenty of unused and available RAM and CPU resources. Firefox behaves normally after restarting.

OS: Xubuntu 22.04 Firefox version: 120.0 (though previous versions have been affected for the last few months)

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?
