Firefox Support Forum

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.

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

this site sucks by the way keeps eating what i type

Firefox version 127.0 Ubuntu 22.04.4

bookmarks toolbar under address bar broken setting set correctly for it to be there and there is a blank space for it to be there but none of my bookmarks that are in that folder show up changing the settings make the blank bar disappear and come back see screenshot.

Firefox home page is missing even though it is set to display just get blank screen on both new tabs and at start up of browser even though it is set to show Firefox start screen.

now every time i start Firefox it demands my master password for my passwords? just hitting cancel makes it go away though.

right click copy only works like 1/4 the time allot of the time the even though the text is highlighted copy is greyed out but using control+c usually works. that one has been happening a wile though.

I know it seems like a minor thing, but I run my browser in the left hand of my screen with other apps to the right, so that gaps pushes all my pinned tabs and browsing tabs over to the right losing valuable space. It's not there on my Windows machines where I run a similar layout.

Anything that I can do about it in about:config?

Hi

I just clicked on my Firefox to open it and was met with a new update tab, and all my tabs had disappeared, which I have had happen to me in the past and ended up losing everything after closing Firefox and reopening it again.

So with that in mind I went to History and everything was greyed out, and so had no option but to close my browser, thinking that maybe that it had opened that one to tell me about the update and if I reopened it all my tabs would be there. Is there anyway I can retrieve all my tabs?.

Thanks

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.

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).

Even though I have browser.privateWindowSeparation.enabled set on "false", private windows appear separate regardless and it is bothering me. I restarted my browser, logged out and then back in, toggled the setting on and off again, but the damn thing stays in this uncomfortable spot that would be awkward to explain as opposed to simply having it blend in with the other windows innocuously. How do I fix this?

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.

When I open my emails, I get an automatic default to email REPLY. I cannot open my emails for reading and attachments. Also, I no longer get the time of the email listed. How do I restore my settings?

Hi there,

I'd like to know if there is a way to remove firefox relay from the context menu, as per screenshot. I really like the relay icon on the email fields, but I don't want it to show on the context menu and I found no such option on the relay extension. Is there a solution to this?

Thank you

Websites say that my Javascript is disabled, but I already checked on the about:config website and the javascript.enabled is set to true. What do I do so these websites accept that my Javascript is enabled?

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

The vast majority of the time, when I open a new tab, I want to go to a page I already visited. Unfortunately, I consistently have to press down arrow to get to what I'm looking for.

I already disabled any kind of search suggestion (settings screenshot attached), added the separate search field, but nothing I tried removed the "Search with DuckDuckGo" being the first suggestion. I pressed the down arrow so many times in my life because of this, I'm at a loss.

Am I missing something? Is there any way to get the history suggestions to be before ANY web search.

I have been trying to read article comments on Fox News Digital (https://www.foxnews.com), but the comments are not showing up. I am using a MacBook Air with Sonoma 14.1. I am using FireFox latest edition and have updated FireFox but comments are still not showing up. Comments do display in Safari logged in to foxnews.com or not. I would put a jpg in this request for assistance, but it wouldn't show much just a white space where the comments should be.

I have a Lenovo Win 11 notebook that now requires me to sign in each time I open Outlook or YouTube when I use the Firefox Browser. Edge and Chrome do not require a sign each time I use Outlook and/or YouTube. A setting in Firefox certainly seems to be the cause. I reinstalled Firefox, still same broblem.

A week or two ago I had no issues with Outlook and YouTube. It happens now every time I Open Outlook and YouTube.

I now use EDGE and have stopped using Firefox which has been my preferred browser for years.

Best regards,

Hi,

Just the other day I started getting these popups from "anti virus service" that keeps popping up on my screen. I do not nor never did have McAfee on my system. I did a deep search, and there is no program on my computer, nor in my startups, nor in my popups allowed relating to this. It is only a problem with Firefox. Any solutions?

Thank you, John
