Having Firefox open reduces all download speeds, upload unaffected

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

  • Rebooted
  • ipconfig /release /renew /flushdns
  • Removed and reinstalled the network adapter
  • Enabled, disabled windows auto tuning and tested (slower disabled)
  • Updated Windows
  • Refreshed Firefox
  • Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

My issues:

1) Every time I close Firefox I get the Mozilla Crash Reporter telling me that Firefox has crashed. Sometimes I even get the Mozilla Crash Reporter when I start Firefox. But Firefox is still there.

2) When I turnoff my Comodo Firewall, Firefox has no Internet connection.

I have done clean uninstalls/reinstalls over and over. I go thru and adjust settings. My other browsers work fine, including WaterFox, WaterFox Classic, and Vivaldi.

I tried turning off my security software to test. Specifically exiting Comodo Firewall seems to have caused Firefox to not have an Internet connection. All other browsers have Internet access except Firefox. And the Crash Reporter cannot "report" when the Firefox Internet connection does not work, though I did have it report many times when the connection DID work.

One other clue: In Task Manager I see that even though I have closed Firefox, there over 20 instances of it still running. When I try to open it again, I get the "Firefox already running" error message. When I try to kill these instances/processes many will not close.

This problem has been persistent for more than half a year since I built my new PC. I am on Windows 10 LTSC. Besides Comodo Firewall, Emsisoft Anti-Malware is my main anti-malware.

Please help! Thank you!

This is the third time I've lost all my passwords (and logins) since the beginning of the year. I had over 200 when I lost it the first time. I've entered over 75 since then and today I just lost those. Fortunately, I had a backup of my profile. The old "key4.db" and "logins.json" files I had didn't work, although they have a significant size. In fact, looking at the "logins.json" using VS Code I see the logins are there but they don't display in the "Settings > Privacy & Security". How can I get access to them when this happens again. I was able to restore the profile from several days ago so I'm not completely in trouble.  :-)

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

Hi,

Almost daily, I have to delete cert9.db and restart Firefox, otherwise I can't access some websites, or even web interfaces of local devices on our LAN.

security.enterprise_roots.enabled is greyed out, so I can't change that but it is set to "true", which I believe means that it should be using Windows Cert store and not cert9.db. Yet still, deleting cert9.db is the solution to my issues.

Can anyone advise on what I can do for a more permanent fix?

Thanks,

M

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

  • Restarting Firefox fixes it for a short while
  • I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
  • Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

Just got a new laptop with Windows 11, installed Firefox, and am running FF 98.0.1. When scrolling on some pages, the buttons look like they're constantly flashing. But if I scroll slowly, I can see that the button color is itself scrolling within the button boundary. Or at least, that's what it looks like. Attached a sequence of images to show what I mean. Can anyone help? It's so irritating that I might be forced to use a different browser, which I don't want to do! This didn't happen on my old laptop running Window 10.

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

Hi everyone,

Up until the latest FF release, opening an .ics (calendar file) link defaulted to the OS's preferred application; in my case Outlook. Now, every time I click on an .ics link FF asks where I want to save the file. I schedule ZOOM meetings all day and heavily rely on this feature.

I tried looking in FF's Files and Applications section in settings and .ics is not even listed as a file extension. I don't know how to add it.

Any assistance is greatly appreciated.

Just now, after a massive and catastrophic SUPER-MELTDOWN-crash that arbitrarily decided to absolutely murder my day, ALL my tabs and windows and ALL history of "Recently Closed" tabs and windows is gone!

THIS IS COMPLETELY UNACCEPTABLE!

What is the reason for the existence of a SYNC feature if it isn't to MAKE SURE that a record of open tabs and windows is SECURELY maintained no matter how many times the application crashes, so that AT ALL TIMES, this information is kept INTACT, regardless of the state of the end users device? That is BY FAR the most important part of the sync feature! Are you telling me that there is no backup process of that information?

This is the kind of thing I never expected from you guys at Mozilla. I've been using Firefox for MANY years because I trust what you do. Today that trust has been SEVERELY and BRUTALLY wounded, most likely beyond repair...

I need you to fix this...

I need you to recover that information for me and I need you to make sure that what just happened could never, ever happen again unless God himself caused every digital storage unit on earth to disintegrate.
