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.

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts.

But Youtube plays fine in Chrome and Edge.

I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago.

Is there any way to reset something?

Fixed, see /questions/1450036 Solved 6/15/2024 problem of frozen screen

Apologies if I'm repeating a previous request - couldn't tell if it was submitted.

I'm running Windows 10. While changing the startup screen somehow an image I thought was deleted appeared and now is frozen, apparently on top of a Firefox window. I've rebooted, restarted and followed the Windows help suggestions with no success. Right now I don't know whether this is a Firefox or Windows problem. I updated Firefox today to the newest version before this happened.


Any help will be appreciated. I can open new Firefox windows.

P.B.

Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like to used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Back in October 2022, changes were made to how private windows appear, separating their icon in the OS taskbar, giving it a new icon, and putting a badge on the top right of the window.

At the time, support threads (such as this one https://support.mozilla.org/en-US/questions/1393494#answer-1542568 ) suggested changing three options to revert these changes: -browser.privateWindowSeparation.enabled -browser.privatebrowsing.enable-new-indicator -browser.privatebrowsing.enable-new-logo I really dislike how these changes look, and so immediately followed this advice. In my advanced options, every one of these is still set to "false" to this day. However, after a recent Firefox update (my current version is listed as 127.0), these no longer seem to have any effect making the new look the only option.

I would strongly prefer to at least re-combine the taskbar icons for standard and private browsing into a single icon. Is there any way to do this in the current update, or is this change permanent going forward? If it is permanent, would reverting to version 126.01 risk losing my current Firefox profile?

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

Firefox 127 - close tab button missing for background tabs when more than 10 tabs opened

In previous versions I was able to open around 15-20 tabs before X button disappeared from them and I was no longer able to close them without activating them first.

Now this happens much earlier - only 10 tabs is enough on my 1080p 100% scaling desktop and 9 tabs on my 1080p 125% notebook.

X button is present if you have 10 tabs or less, but disappears with 11 tabs, when there is still plenty of space on tabs to click on X!

I compared it to brave and in brave you can still have 22 tabs opened before X button disappears!

Anyone has any method to force presence of x button? This is really annoying as I often have much tabs open and close only 2-3 of them. Now I have to open each one again to be able to close it.

The icon for private browsing has recently re-appeared on my taskbar despite having browser.privateWindowSeparation.enabled set to false in about:config.

I've had this setting configured ever since the update which completely changed the appearance/behavior or private browsing and it has worked correctly up until today (14/06/24).

Is there a new setting that I have to adjust in order to "merge" the windows together as I'm not a fan of having the private browsing icon on my taskbar.

Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

Hey guys,

I followed the instructions but it did not work for me. Yes, I did save the changes I made, and I completely closed & reopened Firefox, but the changes I made have not been applied for some reason. Please see the attached image.

I would have ask the question in the aforementioned thread but it's been archived so I had to open a new one. Does anyone know why Firefox does not seem to recognize my custom values (.75, .85)? Thanks!

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

  1. Launch Linux FF
  2. Visit this page "Potential issue with plugin PITM" (Preview here
  3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
  4. After my approval for the account please visit again "Potential issue with plugin PITM"
  5. Click "1.png" Below heading "Attachments", that should work without problems.
  6. Close image view
  7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
  8. Now Click that image
  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?
