Hi Firefox Team,

I wanted to ask, whether you know any solution to my streaming problem. I noticed that my download speed is incredibly fast, when I am running a download in the background of my PC. This can be a windows-update or updating a game via steam. But when I am not downloading anything, then Youtube cant even stream 360p without buffering every 10 seconds. I feel like the Firefox-Browser is not telling my PC that it needs the internet and thus does not get it, but when another program needs internet, It gets enough to work.

Firefox Upload Speed Severely Bottlenecked (1/4th of ISP Speed) on Windows - All Troubleshooting Exhausted - Other Browsers/Apps Fine

Hello,

I am having major issues with Firefox speeds, Mainly upload speeds. On Edge I am getting 400 up & down (no issues at all). However, on Firefox upload speed is 144 Mbps, same on private windows. The only issue is with Firefox. Windows is up to date and Firefox version is 139.0.4 (64-bit)

Attached comparison screenshots for reference.

Below are the steps i performed:

=========================

Firefox Troubleshoot Mode Test: Download: 411.71 Mbps (Full Speed) Upload: 173.03 Mbps (Still Bottlenecked) Extensions Disabled Manually (Normal Firefox): No significant improvement. Hardware Acceleration Toggle (Normal Firefox): No significant improvement.

=========================

New Temporary Firefox Profile Test: Download: ~333 Mbps Upload: ~190 Mbps Problem persists even with a clean profile.

=========================

Temporarily Disable Windows Firewall Test: Resulted in ~349 Mbps Down / ~148 Mbps Up. Firewall re-enabled.

=========================

Could someone let me know how to get this fixed. Creating a new profile should have fixed issued assuming one of the extensions was causing the bottleneck. But even with a new profile its not making any difference.

Once I visit any web site that uses HTTPS there is approximately a 90% chance it'll take seconds or even minutes to secure the connection. This never happens on other browsers as they load such pages instantaneously.

I already cleaned my data up and removed the extensions, both suspected and innocent bystanders, to no avail.

As stated in the title, I'm using Firefox 139.0.1 x64 on Windows 11 (24H2, build 26100.4061). This started happening after an automatic Firefox update, I never changed anything in my system configuration.

Firefox is no longer compatible with my bank's system. I can't log in with the secure access code the bank sends to verify my identity when using Firefox. The bank says it is a problem with Firefox. Other browsers work flawlessly ... are you working on a solution? I only use Firefox unless forced to use something else ...

Suddenly this morning Firefox stopped connecting to any websites. It never gives an error message, it just tries to connect forever. Chrome and Edge can both access the internet without problems. I'm running Windows 11 Pro, and here's what I've tried so far:

Malwarebytes disabled Firewall disabled Turned off all add-ons/extensions Firefox uninstalled and reinstalled Firefox, Windows, Malwarebytes, etc all updated Cache & cookies cleared Refresh Proxy use disabled IPv6 enabled DNS prefetching set to "true" Full malware scan by Malwarebytes Computer restarted (several times)

Any other ideas? Thanks!

Trouble viewing websites with Firefox

I am having difficulty trying to view a website. I receive the following message whenever I try to view this website:

"Suspected Phishing This website has been reported for potential phishing.

Phishing is when a site attempts to steal sensitive information by falsely presenting as a safe source."


There are two buttons beneath this message, the one on the left which reads "Learn More," the one on the right which reads "Ignore & Proceed." Yet when I click on either of the buttons a blank white page appears.

The web address in the URL field also changes from the website I originally selected to the following:

https://www.smartredirect.de/redir/clickGate.php?u=IgKHHLBT&m=1&p=8vZ5ugFkSx&t=vHbSdnLT&st=&s=&url=http%3A%2F%2Fwww.brutaltops.com%2F&r=https%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3DBrutalTops.com%26sca_esv%3D9a8e8f6bd3ba345e%26source%3Dhp%26ei%3DHMO2Z6SJBaqWwbkP7JzXUA%26iflsig%3DACkRmUkAAAAAZ7bRLHc87-cSI48xaawgAj9EjL-Nm71U%26ved%3D0ahUKEwikh43Vx9GLAxUqSzABHWzOFQoQ4dUDCBM%26oq%3DBrutalTops.com%26gs_lp%3DEgdnd3Mtd2l6Ig5CcnV0YWxUb3BzLmNvbUjNa1CbCliBWXABeACQAQCYAW-gAfcKqgEEMTYuMbgBDMgBAPgBAZgCCaAClwaoAgrCAgoQABgDGOoCGI8BwgIKEC4YAxjqAhiPAcICERAuGIAEGJECGNEDGMcBGIoFwgILEAAYgAQYkQIYigXCAg4QLhiABBixAxjRAxjHAcICBRAuGIAEwgIREC4YgAQYsQMY0QMYgwEYxwHCAgsQLhiABBjRAxjHAcICCBAAGIAEGLEDwgIXEC4YgAQYkQIYsQMY0QMYgwEYxwEYigXCAgUQABiABMICCxAAGIAEGLEDGIMBwgIIEC4YgAQYsQPCAg4QLhiABBixAxiDARiKBcICCxAAGIAEGJIDGIoFwgILEC4YgAQYsQMY1ALCAhEQABiABBiRAhixAxiDARiKBcICFBAuGIAEGJECGLEDGIMBGNQCGIoFwgIREC4YgAQYkQIYxwEYigUYrwHCAg8QABiABBixAxgKGEYY-QHCAgoQABiABBixAxgKwgINEAAYgAQYsQMYgwEYCsICBxAuGIAEGArCAgcQABiABBgKwgIFEAAY7wWYAxPxBQrZJeqRYy6tkgcDNi4zoAeUYg%26sclient%3Dgws-wiz



Why would I not be able to view this website (and others too) with Firefox but am able with Chrome? I want to be able use Firefox, as Chrome will not allow use of an extension that Firefox will.

Please tell me how this problem may be fixed.

I have tracked down the situation where my Internet download speeds drop from about 598 Mbps to around 267 Mbps after I open Mozilla. I am running a desktop computer with Windows 11 (updated) and Edge and Chrome. I am hardwired directly to my Xfinity modem (no WiFi connection). When I close Mozilla, my speed goes to 598 Mbps, and when I open Mozilla, my speed drops to 267 Mbps. This seems excessive and unacceptable. Are there any settings or anything to adjust, not to have Mozilla be such a drain on my system?
